eLife assessment

The authors describe a sophisticated method to follow enhancer activity in both live embryos and fixed embryos in Tribolium and present important data about the function of a number of enhancers in early development. They show that some of the enhancers are "dynamic" and others are "static" and use this to provide support for the "enhancer-switching" model of gene regulation suggested by some of these authors in the past. However, the evidence they provide is incomplete and although it is consistent with the model, it does not directly support it.

eLife assessment

This study presents findings that are important for understanding plant-soil feedbacks in agriculture. The authors use a large-scale agricultural field experiment to demonstrate the role of root-emitted secondary metabolites in enhancing the yield of the next crop. By using a benzoxazinoid-deficient maize genotype, the authors provide compelling evidence that biomass production and grain yield of several wheat varieties can be increased when grown in soil conditioned by maize plants able to release benzoxazinoids.

eLife assessment

This valuable work investigates the fundamental concept of how the energy of agonist binding is converted into the energy of the conformational change that opens the pore of a ligand-gated ion channel. The conclusions are based on analysis of solid data in terms of a mechanistic model, but adequate statistical analysis is lacking and the uniqueness of the proposed model is not discussed. The findings will be interesting to biophysicists working on ligand-gated ion channels and, more generally, to enzymologists focused on allosteric enzyme regulation.

eLife assessment

This valuable study provides insights into the IDA peptide with dual functions in development and immunity. The approach used is solid and helps to define the role of IDA in a two-step process, cell separation followed by activation of innate defenses. The main limitation of the study is the lack of direct evidence linking signaling by IDA and its HAE receptors to immunity. As such the work remains descriptive but it will nevertheless be of interest to a wide range of plant cell biologists.

This important study combines experiments and fluid mechanics modeling to determine the mechanism of the ultrafast ejection of the polar tube of the Microsporidia parasite and of transport through this tube. The methods and the analysis, based on the variation of the viscosity of the external medium, are solid, allowing for the first time to discriminate among proposed ejection mechanisms. More details about the model, regarding both the actual topology of the system and the pressure, would be, however, helpful for the reader. The approach implemented here, where simple physical principles are used for distinguishing between mechanisms when the precise geometry is inaccessible through imaging, is potentially applicable to other systems in microbiology.

eLife assessment

This important study used a battery of cutting-edge technologies including whole exosome sequencing, knockout/knockdown animal models and comparative proteomics to define the physiological roles of ZMYND21 in the regulation of sperm flagellar development and male fertility.

This small-sized clinical trial comparing nebulized dornase-alfa to best available care in patients hospitalized with COVID-19 pneumonia is valuable, but in its present form the paper is incomplete: the number of randomized participants is small, investigators describe also a contemporary cohort of controls and the study concludes about decrease of inflammation (reflected by CRP levels) after 7 days of treatment but no other statistically significant clinical benefit.

eLife assessment

This manuscript represents a valuable study showing that microplastics indeed accumulate in both bovine and human ovarian follicular fluid. It also presented data that direct exposure of bovine eggs to polystyrene, a microplastic commonly found in follicular fluid, negatively affects oocyte maturation, probably through the downregulation of key proteins involved in oxidative stress, DNA damage, apoptosis, and oocyte maturation. Despite the solid supporting evidence, inclusion of the demographics and reasons for assisted reproduction of the human subjects used, as well as the details on quality control for proteomic analyses would further strengthen the study. The work will be of interest to reproductive toxicologists, regulatory scientists and reproductive health care professionals.

eLife assessment

eLife assessment

This important study combines genetically barcoded rabies viruses with spatial transcriptomics in vivo in the mouse brain to decode connectivity of neural circuits. The data generated by the combination of these approaches in this new way is mostly convincing as the authors provide validation and proof-of-concept that the approach can be successful. While this new combination of established techniques has promise for elucidating brain connectivity, there are still some nuances and caveats to the interpretations of the results that are lacking especially with regards to noting unexpected barcodes either due to unexpected/novel connections or unexpected rabies spread.

eLife assessment

This valuable work proposes a new model of basal ganglia function termed the "Triple Control Model" consisting of one direct pathway and two indirect pathways. The study provides evidence that the firing dynamics of substantia nigra reflect action selection but not interval time or reward and makes a case for the need for the Triple Control Model to explain the results of their manipulations of D1 and D2 receptor-expressing cells in the striatum. Although this work may be of interest to neuroscientists who study basal ganglia, without additional analyses of the relationship of neural activity to movements, and direct experimental evidence of two indirect pathways, the evidence for this model is somewhat incomplete.

eLife assessment

The formation of the place cell map in the hippocampus is foundational to many models and is thought to form a substrate onto which memories can be structured. This paper presents an important new observation to our understanding of place cell formation - namely that task learning changes or interferes with the process of place cell map stabilization. Reviewers found that there was incomplete evidence for this result, however, in this version of the manuscript because of a confound between the duration of experience in an environment and task-specific learning.

This study presents a useful set of experiments to test how a salivary protein might facilitate planthopper-transmitted rice stripe virus infection by interfering with callose deposition. If the conclusions can be confirmed, the study will enhance our understanding of the mechanisms mediating tripartite virus-insect vector-plant interactions and would be of general interest in plant science research. Whereas most experimental data is compelling, the conclusions rely on inadequate evidence for the salivary protein carbonic anhydrase being present two weeks post injection in the plant, which seems unlikely.

eLife assessment

The full role of small RNAs, often key global regulators of gene expression in connection with environmental adaptation, in flagella regulation has not been determined. This study presents important findings regarding the function of small RNAs in bacterial motility and regulation of flagella biosynthesis regulation and number.

Mizukami et al. propose a scenario for the evolutionary origin of the coronary artery in amniotes by comparing the morphologies of the vasculatures across several species and developmental timepoints. They show that the coronary arteries of non-amniotes most closely resemble embryonic amniote aortic subepicardial vessels (ASVs), which are replaced by the true coronary arteries during amniote development. While the identification of common vascular structures in diverse taxa is a valuable contribution, additional developmental evidence is needed to confirm that such vessels are truly homologous.

eLife assessment

This valuable study assesses how change in reward contingency in the environment affects the dynamics of a realistic large-scale neural circuit model, human choice behavior, and fMRI responses measured in the same individuals. It is not entirely clear which predictions of the neural circuit model go beyond previous work, the current results seem incomplete and could likely be substantially strengthened. This study could be of interest to scientists studying the neural and computational bases of adaptive behaviour.

eLife assessment

Traditional approaches for the analysis of brain rhythms typically rely on measuring spectro-temporal properties of individual oscillations or the interactions between two different oscillations. This manuscript presents a novel multivariate approach that uses a state space model to simultaneously analyze the dynamics and interactions of multiple hippocampal oscillations. Such an approach represents a step forward in the field that highlights the need of taking into account the complexity of network interactions rather than trying to understand each component of the system in isolation.

This work will be of broad interest to ion channel biophysicists, physiologists, and medical chemists interested in drug development for LQT syndrome. The study presents some limitations that may need to be addressed or further discussed, in order to strengthen the conclusions reached in the study.

eLife assessment

This study is an important contribution to our understanding of somatic mutation mechanisms in plants, uncovering a surprising constancy in the yearly accumulation of somatic mutations regardless of the species' growth rates. The authors provide compelling evidence, leveraging rigorous sequencing analysis and innovative bioinformatic techniques, to demonstrate that many plant somatic mutations are accumulated in a replication-independent manner. This research is poised to captivate not only scholars focused on plant evolution and development, but also scientists broadly interested in mutation mechanisms in multicellular organisms.

This work is important as it introduces the new concept of trained immunity and its clinical implication.

eLife assessment

This paper covers a large range of effects of delivering SAR-CoV2 spike protein to the airway of mice with some in vitro analysis of effect on human cells. The observations will be valuable to the field in raising the possibility that the SAR-CoV2 spike protein has pro-inflammatory effects following uptake by macrophages and may lead to neutrophil recruitment and netosis, a pro-inflammatory mode of cell death. Two of the three reviewers felt the evidence was incomplete, based on what were felt to be some weak controls, but another expert felt the evidence was solid.

eLife assessment

This important study increases our understanding of the role of heterochromatin domain dynamics during early embryonic development by annotating the change in chromatin-associated proteins as a function of cell state. The authors provide solid evidence to demonstrate that DNA Topoisomerase II Binding protein (TOPBP1) is an ESC-specific chromatin-bound factor that potentially regulates chromocenter reorganization during the 2CLC-ESC transition through interaction with the SWI/SNF complex component SMARCAD1. However, a lack of mechanistic studies to interrogate how TOPBP1 and SMARCAD1 contribute to the reorganization of H3K9me3-heterochromatin or chromocenter concomitant with alterations in stem cell state leaves the current work incomplete.

eLife assessment

This study reports a new approach to determine the architecture of peptidoglycan (PG), the primary component of the bacterial cell wall, validating the pipeline through an architectural analysis of several members of the human gut microbiota. The technique is potentially valuable for this sub-field as it would enable researchers interested in peptidoglycan in a range of organisms to easily assess muropeptide composition in an easy, automated manner. However, there is some uncertainty about whether the pipeline was fully automated. Additionally, the use of the technique to support that PG cross-bridge length is a determinant of cell wall stiffness resulted in incomplete evidence that would need substantiating, more direct support.

eLife assessment

Extracellular vesicles (EVs) are emerging as important mediators of cell-to-cell signaling. Lee et al show convincingly that Stranded at second (Sas), a Drosophila cell surface protein, is trafficked by and localized to Drosophila EVs. However, the data supporting interaction with dArc and whether Sas facilitates the intercellular transfer of dArc protein or mRNA is incomplete. Moreover, almost all experiments rely on gain-of-function and over-expression of Sas, thus the relevance to normal physiological signaling is unclear.

eLife assessment

This is an elegant study combining virally-delivered lineage-tracing with single cell RNA-sequencing of the developing chicken enteric nervous system, showing potentially differential contribution of cell identities from the sacral and vagal neural crest. Addressing this important issue is pivotal to understanding basic enteric nervous system development as well as to devise therapeutic approaches to enteric neuropathies. The study is therefore generally interesting and in particular to researchers in the fields of enteric neuroscience and peripheral nervous system development. Lack of a basic classification scheme of neuronal cell types in the chicken, limited computational and functional analysis on a relatively immature stage and makes the conclusions of this work preliminary in its current state.

eLife assessment

The creation of a single-cell atlas of normal and degenerative human anterior cruciate ligament (ACL) tissues using a single-cell RNA sequencing method is an important approach to understanding the pathological mechanisms of ACL degeneration. The data of this study showed the existence of fibroblasts, endothelial cells, pericytes, and immune cells in healthy ACL, and their ratios altered in the degenerative ACL, mainly exhibited as an increase in fibroblasts and immune cells. The data analysis suggests that alterations of spatial transcriptome and changes in gene expression and signaling pathways may contribute to ACL degeneration.

eLife assessment

This important study pinpoints nitrite oxide synthase 2 activity and decreased microtubule acetylation as distinct regulators of altered autophagic flux that may contribute to pathogenesis in a mouse model of Duchenne muscular dystrophy. While most of the evidence to support these claims is convincing, the claim that autophagy is improved with increased microtubule acetylation is incompletely supported. This work may be of broad interest to muscle biologists and has translational potential for the treatment of Duchenne muscular dystrophy.

eLife assessment

The study is important as the authors successfully developed a human telencephalon-eye organoid model that exhibited remarkable pathfinding and growth of retinal ganglion cell (RGC) axons. The identification of cell-surface markers for RGCs could have significant implications for understanding the molecular mechanisms involved in RGC axon development and regeneration. While the authors' data on the developmental patterning organoid model are compelling, the reviewers had significant concerns, implying that the study could still be substantially improved.

This is an important study that describes the coordinated regulation of cellular size and protein translation in response to chronic stress as an adaptive mechanism regulated by the heat shock response. The evidence supporting this conclusion is solid, utilizing diverse methods to monitor and manipulate cell size and evaluate stress resistance; however, it is currently unclear in the manuscript to what extent the effects observed are confounded by cell overcrowding. Additionally, the study could be strengthened by the inclusion of more experiments focused on defining the mechanistic basis of this coordination. This work will be of broad interest to researchers interested in diverse fields including cellular proteostasis, stress-responsive signaling, and aging and senescence.

eLife assessment

This study provides an important connection between cellular metabolism and proteostasis through MAGIC, a previously proposed protein quality control pathway for clearing cytosolic misfolded and aggregated proteins by import into mitochondria. Using a split-GFP reporter system, the authors reveal the role of Snf1, a yeast AMPK, in preventing the import of misfolded proteins to mitochondria for MAGIC, controlled by transcription factor Hap4 as a function of cellular metabolic status. The experimental evidence provided by the authors is still inadequate for explaining the regulatory mechanism of MAGIC by Snf1 or HAP4 and incomplete for explaining the cellular mechanism of substrate selection for MAGIC.

eLife assessment

This manuscript provides a useful reconstruction of the structure of the sirtuin-class histone deacetylase Sirt6 bound to a nucleosome based on cryo-EM observations, and additional characterization of the flexibility of Sirt6 based on molecular dynamics simulations. The analysis of the cryo-EM data is incomplete for some of the conclusions, and certain elements of the presentation were inadequate to allow sufficient evaluation. Biochemical validation of the conclusions is not provided, but some of this evidence has been published recently by two other groups in their analyses of the same complex. While much in this manuscript is confirmatory, the work also includes new insights into the potential dynamics of Sirt6 bound to a nucleosome.

eLife assessment

This valuable study contributes to understanding how retinal activity shapes the response properties of excitatory and inhibitory neurons in a major visual target, the superior colliculus.

This study by Koh et al reports an important role of key fatty-acid synthesis enzyme, acetyl-coA-carboxylase 1 (ACC1) in development and homeostasis of invariant natural killer T iNKT cells, as well as its significance in asthma etiology. The findings reveal that ACC1 induces de novo fatty acid synthesis via fatty acid- binding proteins (FABPs) and peroxisome proliferator-activated receptor (PPAR)γ axis in iNKT cells, which is critical for iNKT cells survival and their pathogenic roles in allergic asthma. The data reported in the manuscript are convincing, and the work adds to our understanding of the metabolic regulation of iNKT cells.

This important study uses an innovative GWAS approach and targeted testing to highlight S. aureus genes that modify susceptibility to serum, serum-derived antimicrobial products, and commonly used antibiotics. These findings are significant in that they highlight evidence of evolution of virulence determinants in the setting of exposure to host stressors expected to be present during bacteremia and antibiotic therapy. Compelling results build on a foundation of work attributing loss-of-function mutations in tcaA to glycopeptide non-susceptibility.

This important study expands on current knowledge of allosteric diversity in the human kinome by C-terminal splicing variants using as a paradigm DCLK1. The authors provide solid evolutionary and some mechanistic evidence how C-terminal isoform specific variants generated by alternative splicing can regulate catalytic activity by means of coupling specific phosphorylation sites to dynamical and conformational changes controlling active site and substrate pocket occupancy, as well as protein-protein interactions. The data will be of interest to researchers in the kinase and signal transduction field.

This useful manuscript presents a new approach to transform multi-omics datasets into images and to exploit Deep Learning methods for image analysis of the transformed datasets. As an example, the method is applied to multi-omics datasets on different cancers, but the evidence for the method working as advertised is currently incomplete.

eLife assessment

This study offers important insights into the transcriptional regulatory networks driving female gametocyte maturation in rodent malaria parasites. The carefully designed and executed experiments convincingly show how two female-specific transcription factors, AP2-FG and PFG (aka Fd2), co-operate to up-regulate the expression of genes required for development after fertilization occurs in the mosquito midgut. This study will be of interest to scientists working on sexual differentiation and gene regulation in Plasmodium and other apicomplexan parasites.

This fundamental study provides evidence that de novo beige adipogenesis from Pdgfra+ adipocyte progenitor cells is blocked during early aging in subcutaneous fat. The depth of the data at early ages is compelling, with rigorous cell tracing methodology employed. The study will aid in identifying new approaches to switch dormant adipocytes into an active thermogenic phenotype, and should be of interest to cell biologists at large.

eLife assessment

The study by O'Reilly and Delis provides a valuable data-driven framework for extracting task-related muscle synergies in a step towards the understanding and practical use of synergies in real scenarios (e.g., evaluation of patients in a clinical environment). The approach is incomplete since the authors did not compare their method with classical physiologically grounded approaches for assessing muscle synergies. In this sense, the comparisons with classical approaches would clarify if physiological assemblies were preserved and were not altered to incorporate task space variables. Despite limitations, the proposed framework would interest motor control and neural engineering researchers.

eLife assessment

The authors report that an interaction between the sodium-activated potassium channel Slack and Nav1.6 sensitizes Slack to inhibition by quinidine. This is an important finding because it contributes to our understanding of how the antiseizure drug quinidine affects epilepsy syndromes arising from mutations in the Slack-encoding gene KCNT1. The results are largely compelling, although additional data would strengthen the claims of a direct channel-channel interaction in vivo.

eLife assessment

This study presents a valuable finding on developing a generative model of brain electrophysiological signals to explain temporal decoding matrices that have been widely used in cognitive neuroscience. The evidence supporting the claims of the authors is convincing, although adding more neurobiological interpretation of signal properties and the underlying brain mechanism would have strengthened the study. The work will be of interest to cognitive neuroscientists using electrophysiological recordings.

eLife assessment

This valuable study combines chronic widefield calcium imaging of dorsal cortex activity at the mesoscale level with electrical recording of single neurons in specific cortical and subcortical locations.

This work will be of broad interest to system neuroscientists studying neural circuits.

eLife assessment

This study addresses an important question using approaches that link molecular, circuit, and behavioral changes. The findings that Netrin-1 and UNC5c can guide dopaminergic innervation from the nucleus accumbens to the cortex during adolescence are solid. The data showing that the onset of Unc5 expression is sexually dimorphic in mice, and that in Siberian hamsters, environmental effects on development are also sexually dimorphic are solid. While this work is novel and on an interesting, understudied topic, the reviewers also identified significant gaps in experimental data and agree that support for the main claims is incomplete.

This important paper advances our ability to understand feeding behavior in fruit flies and begins to address the challenging question of motivation. With innovative methods based on the detailed monitoring of interactions between foods of different qualities at different hunger states, they present compelling evidence for non-homeostatic feeding not driven by metabolic need.

eLife assessment

This is an important paper that combines methods ranging from agronomy and plant breeding to Arabidopsis functional genetics, to construct a plausible argument that polymorphism in a single gene affects crop yield by affecting root cell elongation and drought stress resilience in a poorly studied crop. The overall argument is plausible but rests on a diverse set of claims that are supported by solid, but also partly incomplete evidence.

eLife assessment

This study presents Bactabolize, a useful tool for the rapid genome-scale reconstruction of bacteria, applied here to strains of Klebsiella pneumoniae. Using a solid and validated methodology, the tool takes reference reconstructions as the input and can generate new reconstructions for target strains from these. However, the evidence to substantiate all of the justifications and practical applications of the models produced is still incomplete, and the work would benefit from more rigorous approaches regarding the accuracy of the predicted models.

eLife assessment

This paper describes useful tools for the light-induced degradation of proteins in bacteria, which will be appreciated by the community. The methods and data analyses are solid but the strength of evidence for the tool working as advertised is still incomplete. The study will be of interest to colleagues in the fields of microbiology and synthetic biology.

eLife assessment

This is a valuable investigation of the chromatin dynamics throughout the cell cycle by using fluorescence signals and patterns of GFP-PCNA and CY3-dUTP, which labels newly synthesized DNA. The authors report reduced chromatin mobility in S relative to G1 phase. The technology and methods used are solid, but the significance of the work is reduced by the model system employed, the HeLa cell line, which has a greatly abnormal genome.

eLife assessment

This manuscript provides useful information on the evolution of gene expression levels and plasticity in tissues impacted by hypoxia during colonization of a high-altitude environment. The strength of evidence is still inadequate because of limitations in the methods and analyses. The work will be of interest to biologists working at the interface of ecology and evolution.

This important study describes the protective role of group 2 innate lymphoid cells (ILC2s) in tissue physiology and contributes to immunity, inflammatory pathology, and metabolism in maintaining homeostasis during pregnancy. The authors provide convincing evidence that ILC2s have new roles distinct from parasite protection and allergy inducers. Uterine ILC2s are key immune cells during normal and complicated pregnancies.

eLife assessment

This study presents valuable new insights into the role of the extracellular matrix component (ECM) Perlecan in axon integrity, with downstream consequences for the maintenance of synaptic structures. The evidence for Perlecan's role in this process is solid, although negative results for Perlecan's mechanism of action should be strengthened with the addition of appropriate controls centered on the relevant pathways and mechanisms involved as well as more careful analyses and interpretations. The authors provide convincing data identifying and describing the cellular sequence from ECM perturbations to axonal and synaptic degeneration, but additional data pinpointing the requirements of Perlecan for axonal maintenance would further improve the impact of this study.

eLife assessment

The present study offers valuable insights into the remodeling of Merkel cells and their innervating sensory axons in the skin. This remodelling seems to be mostly played out independently between the two synaptic partners revealing significant Merkel cell turnover and axonal plasticity. The authors employed live imaging and quantification tools using genetic models in which parts of the mechanosensory organs of the skin are labelled with distinct fluorescent proteins. While most of the data, and their interpretations are solid, the analyses of Merkel cell number homeostasis remain incomplete.

eLife assessment

This study offers an inventory of proteins and their phosphorylated sites that are up- and down-regulated in the adipose tissue and skeletal muscle of women with PCOS. The data were collected and analyzed using rigorous and validated methodology, making it a useful resource for identifying targets and strategies for future PCOS treatments. However, even though some of the predicted targets are compelling, further functional validation is required to ensure the accuracy of these identified targets. If confirmed, the findings of this study would be of significant interest to a wide range of readers.

This important paper highlights the clonal organization of the dorsal telencephalon, a major region of the vertebrate brain, and analyzes the distinctive gene expression and chromatin accessibility present in each clonal using the adult teleost fish medaka. High-quality data were collected using convincing and solid methods and these were used to identify synaptic genes with a distinct chromatin landscape and expression in one of the regions of the dorsal pallium, with the goal of ascribing an evolutionary origin to these neurons.

eLife assessment

This paper is of potential interest to both the hippocampal and computational neuroscience fields because it provides a framework for understanding how adult-born granule cells in the hippocampus contribute to network processing. It contains novel interesting ideas, such as the analysis of input-output transformation by SRM models and the establishment of "greedy networks". However, not all major conclusions are sufficiently supported by the data. The paper demonstrates that mixed networks show better encoding performance than pure networks, but the differences are small and only visible with specific performance metrics. Intuitive explanations are not provided.

eLife assessment

In this study, the authors use high-speed and high-resolution imaging to investigate the role of the yeast syntaxin homolog Tlg2p in endocytic vesicle sorting. They obtain compelling data to show that the Tlg2p-residing compartment within the trans-Golgi network functions as an early/sorting compartment, where endocytic cargos are sorted to either the recycling pathway or the endo-lysosomal pathway. The authors also describe additional molecular details of this sorting process, and overall provide important insights into the mechanism of endocytic vesicle sorting in budding yeast.

eLife assessment

This valuable study shows that new, virulent genotypes of Xanthomonas oryze pv. oryzae, that are similar to strains present in east Asia, cause outbreaks of bacterial blight of rice in Tanzania. The authors' use of CRISPR-based gene editing on multiple pathogen targets in an elite African rice variety to create lines resistant to both endemic and emerging pathogen strains in Africa makes for a compelling contribution to meet this alarming development. The work describing the new strains of the pathogen is solid but could be stronger if there were genome sequence data for all strains examined and a clearer presentation of recent disease outbreaks and their severity.
