Over the last 25 years, shotgun metagenomic sequencing1 and associated computational methods have developed as robust, efficient ways to study the taxonomic composition

MetaPhlAn 4 relies on ~5.1M unique clade-specific marker genes identified from ~1M microbial genomes (~236,600 references and 771,500 metagenomic assembled genomes) spanning 26,970 species-level genome bins

Degenerate consensual pairs of rpoB primers called Univ_rpoB_F_deg (forward primer) and Univ_rpoB_R_deg (reverse primer) were manually designed from clustalW alignments

we constructed a reference database including ~ 45000 sequences; this database is available from the FROGS website (http://frogs.toulouse.inra.fr/).

In many cases, such variations reflect differences in the essentiality of genes. Genes with higher connectivity are often more essential for the reproductive success of a cell or organism

poses challenges for many classical methods, such as parametric statistical tests (for example, Student’s t-test and ANOVA) and measures of correlation, including Spearman’s rank correlation, often leading to completely unacceptable false discovery rates above 90%

We recommend that these methods replace OTU-based approaches for all applications, except when it is necessary to combine sequence data that were generated using different technologies (that is, Illumina sequencing and 454 pyrosequencing) or with different primer sets, when mapping to a common reference database of full-length sequences is often still needed

The number of k-mers in each hash bin is tabulated

If rearrangement events and horizontal transfers are rare for the 16S rRNA gene, as is widely believed to be the case, then its true gene tree is likely to be a good approximation to the true phylogenetic tree based on vertically inherited traits, assuming that the latter tree can be meaningfully defined

If an environmental sequence is annotated as belonging to a taxon which is defined by traits, then this is a prediction which can always be checked in principle

highly multiplexed ribosomal (r)RNA-FISH

The diversity of bacteria can also be accessed by using COI, rpoB, cpn60 (encodes for chaperonin protein), tuf (elongation factor), RIF (Replication initiation factor), and gnd (Gluconate-6-phosphate dehydrogenase) gene as barcode

The origin of the rain is not clear. Rain often is attributed to delayed PCR onset [3] or partial PCR inhibition in individual droplets [4]. However, it could also be a consequence of damaged positive droplets with corresponding reduced fluorescence, or damaged negative droplets with increased background fluorescence, or a mixture of both [5].

we found that the clouds can become more compact and produce substantially less rain upon: (i) reducing the ramp rate to 1 °C/sec in every PCR step (Fig. 10a), (ii) increasing the annealing/extension time to 2 minutes (up from 1 minute; Fig. 10b), and (iii) increasing the number of cycles to 50 (Fig. 10c)28

Trans-splicing ribozymes can, in principle, target every uridine residue of a substrate RNA, but the target sites need to be accessible.

In this assay, the mRNA is incubated with trans-splicing ribozymes that carry a randomized internal guide sequence (IGS). This enables the ribozyme population to splice on every accessible site on the mRNA. The sites at which trans-splicing occurred were identified by RT-PCR, cloning, and sequencing

we performed RT-qPCR on the high-performing RENDR design, split site 15. We observed a 93-fold increase in the abundance of spliced mRNA in cells expressing both RENDR and RNA input compared to control cells lacking the RNA input

At all stop signs, cyclists must stop and yield the right-of-way to other vehicles and pedestrians already at the intersection. RUPD will ticket cyclists for right-of-way violations at intersections.

human cells could serve as an orthogonal system for studying PopZ condensation outside of the context of its Caulobacter binding clients

to improve the accuracy of taxonomic assignment at the species level for full-length 16S rRNA sequences, we manually curated the three databases and removed the sequences that did not have a species name

for example, Vandeputte et al. (2017) measured total-community abundance using flow cytometry

However, the abundance of one species may not influence the abundance of another; the area may contain both tigers and ladybugs, and the migration of several ladybugs into the area would not be expected to affect the number of tigers. The assumption of true independence can not hold in high-throughput sequencing (HTS) experiments because the sequencing instruments can deliver reads only up to the capacity of the instrument.

DNA fragmentation by restriction digestion prior to dropletgeneration enables optimal accuracy by separating tandemgene copies, reducing sample viscosity, and improving templateaccessibility for input samples >66 ng per well

Diluent Buffers (A, B or C) are recommended for making dilutions of restriction endonucleases. When necessary, we recommend diluting enzymes just prior to use and suggest that the final concentration of diluted enzymes be at least 1,000 units/ml

Digestion is recommended whenever DNA input is greater than 75 ng

An RMD assay comprises a single set of primers plus two competitive probes (each probe with a different fluorophore), one detecting the wild-type allele, and one detecting the variant allele.

Drop Off (DOF) Determines absolute quantification of targets for assays designed to detect non-wild type sequences, such as indels and genome edits. The experiment type isdesigned to support an assay strategy where one probe counts all alleles andone “drop-off” probe sits on top of a predicted cut site.

Tm enhancers for probes are recommended for single nucleotide polymorphism (SNP) and rare mutation detection assays in order to keep the background fluorescence to a minimum. Shorter probes discriminate better between single base differences in the target amplicon(s)
