A dietary phytochemical alters caste-associated gene expression in honey bees

Please place treatment free research here. There's a lot of research spread around the Internet that is related to treatment free beekeeping. This forum is an effort to try and consolidate some of this, especially new research as it becomes available.

A dietary phytochemical alters caste-associated gene expression in honey bees

Postby ExpatBeekeeper » Sun Aug 30, 2015 10:12 pm

In the eusocial honey bee Apis mellifera, with reproductive queens and sterile workers, a female larva’s developmental fate depends on its diet; nurse bees feed queen-destined larvae exclusively royal jelly, a glandular secretion, but worker-destined larvae receive royal jelly for 3 days and subsequently jelly to which honey and beebread are added. RNA-Seq analysis demonstrated that p-coumaric acid, which is ubiquitous in honey and beebread, differentially regulates genes involved in caste determination. Rearing larvae in vitro on a royal jelly diet to which p-coumaric acid has been added produces adults with reduced ovary development. Thus, consuming royal jelly exclusively not only enriches the diet of queen-destined larvae but also may protect them from inhibitory effects of phytochemicals present in the honey and beebread fed to worker-destined larvae
