The rise and fall of major royal jelly...
The genome of the western honeybee (Apis mellifera) harbors nine transcribed major royal jelly protein genes (mrjp1‐9) which originate from a single‐copy precursor via gene duplication. The first MRJP was identified in royal jelly, a secretion of the bees’ hypopharyngeal glands that is used by young worker bees, called nurses, to feed developing larvae. Thus,…
