The Effect of Diet on the Composition and Stability of Proteins Secreted by Honey Bees in Honey

Honey proteins are essential bee nutrients and antimicrobials that protect honey from microbial spoilage. The majority of the honey proteome includes bee-secreted peptides and proteins, produced in specialised glands; however, bees need to forage actively for nitrogen sources and other basic elements of protein synthesis. Nectar and pollen of dierent origins can vary significantly in…

The rise and fall of major royal jelly proteins during a honeybee (Apis mellifera) workers’ life

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,…
