Genes influence behavioral variation through allelic differences and age‑dependent changes in expression, as shown by distinct foraging variants in Drosophila. In honey bees, the transition to foraging is linked to increased foraging‑gene expression and PKG activity, and cGMP‑induced PKG activation triggers foraging behavior, demonstrating that the same gene can affect behavior in multiple ways.
Genes can affect natural behavioral variation in different ways. Allelic variation causes alternative behavioral phenotypes, whereas changes in gene expression can influence the initiation of behavior at different ages. We show that the age-related transition by honey bees from hive work to foraging is associated with an increase in the expression of the foraging (for) gene, which encodes a guanosine 3',5'-monophosphate (cGMP)-dependent protein kinase (PKG). cGMP treatment elevated PKG activity and caused foraging behavior. Previous research showed that allelic differences in PKG expression result in two Drosophila foraging variants. The same gene can thus exert different types of influence on a behavior.
