Natural selection on crosstalk between gene regulatory networks facilitates bacterial adaptation to novel environments.

Abstract excerpt

At the level of the gene, mutation is the raw material for natural selection. However, at the level of the gene regulatory network (GRN), variation is revealed to selection via promiscuous regulator activity ('crosstalk'), which creates opportunities for genetic innovation that can facilitate adaptation. Many genetic and environmental features can contribute to increasing potential for crosstalk by facilitating...
