  • QMP-regulated cDNAs were compared to the lists of cDNAs significantly up-regulated in nurse bees or up-regulated in foragers. A significantly larger proportion of QMP ↑ (up-regulated) cDNAs were on the nurse list than were QMP ↓ cDNAs. Likewise, a significantly larger proportion of QMP ↓ cDNAs were on the forager list than were QMP ↑ cDNAs (P < 0.001, χ2 tests). Genes chronically regulated by QMP showed the same trends.
