Genomic footprint of evolution of eusociality in bees: floral food use and CYPome “blooms”

Comparative analyses of genomes of ten bee species representing different degrees of social complexity have demonstrated that independent transitions to eusociality are often accompanied by or lead to expansions or contractions of gene families (albeit different families across independent lineages). Because collective gathering, processing, and storage of plant products is a hallmark of bee social complexity, we examined the genomic inventory...
