Abstract
The evolution of separate sexes may involve changed expression of many genes, as each sex adapts to its new state. Evidence is accumulating for sex differences in expression even in organisms that have recently evolved separate sexes from hermaphrodite or monoecious (cosexual) ancestors, such as some dioecious flowering plants. We describe evidence that a dioecious plant species with recently evolved dioecy, Silene latifolia, has undergone adaptive changes that improve functioning in females, in addition to changes that are probably pleiotropic effects of male sterility. The results suggest pervasive adaptations as soon as males and females evolve from their cosexual ancestor.Entities:
