| Outline of Final Research Achievements |
Royalactin induced queen differentiation in honeybee. The mechanism through which RJ regulates developmental time in honeybees and fruit flies has remains elusive. Here, we investigated how RJ or royalactin decreased developmental time in honeybees and flies. We found that HR38 regulated developmental time in honeybees and flies without affecting body size. Microarray analysis revealed that HR38 induced gene expression of factors involved in formation of the epidermis, imaginal disc formation and larval heart development.
