Fig. 2. Foraging experience and juvenile hormone-target gene expression in the brain. Gene expression ratios for forager/nurse from ref. 1 are plotted on the x-axes; gene expression ratios for forager / hive-restricted bees (presumptive foragers without light, flight or foraging experience; see Methods) from Experiment 3 are plotted on the y-axes. (A) Nurse-forager marker genes that were regulated by methoprene (p < 0.05; red triangle, up-regulated; blue square, down-regulated). (B) Nurse-forager marker genes not regulated by methoprene (p > 0.2).
