Unravelling the evolution of complex reproductive traits with phenotypic engineering.

abstract：:The attine ants are a monophyletic lineage that switched to fungus farming ca. 55-60 MYA. They have become a model for the study of complex symbioses after additional fungal and bacterial symbionts were discovered, but their abdominal endosymbiotic bacteria remain largely unknown. Here, we present a comparative microb...
