Re: Queen development

And that isn't even the whole picture. Here, referring to work published in SCIENCE VOL 319 28 MARCH 2008:

> Although royal jelly is enriched in various B vitamins, the mechanism apparently involves decreased DNA methylation rather than an increase based on RNAi experiments. When a DNA methyltransferase (DNMT3A) was knocked down in honeybee larvae, 72% of the females developed into queens without being fed royal jelly (Kucharski et al., 2008). This finding suggests that royal jelly decreases DNA methylation in order to endow queens with their ability to reproduce via fully developed ovaries and other profound physical and behavioral changes including increased body size and longevity.
