eLife assessment
The authors study how cells with lower levels of the conserved steroid hormone signaling component Taiman (tai) are out-competed by neighboring wild-type cells with higher fitness in Drosophila imaginal discs. The findings are useful since they uncover an unexpected link between tai and Wingless signaling in cell competition. The evidence however is incomplete, since the tai loss-of-clone phenotype is based on one allele and the mechanism involved in cell competition through Dlp and Wg lacks adequate supporting data.
