A Laterally Transferred Viral Gene Modifies Aphid Wing Plasticity

Organisms often respond to changing environments by altering development of particular traits. These plastic traits exhibit genetic variation; i.e., genotypes respond differently to the same environmental cues. Theoretical studies have demonstrated the importance of this variation, which is targeted by natural selection, in adapting plastic responses to maximize fitness [1Leimar O. McNamara J.M. The evolution of transgenerational integration of...
