Summary of the estimated expression intensities in contigs with detectable sex biases in expression in S. latifolia males and females due to changes that are mainly in females or males). The changes in each sex, relative to the expression in the hermaphrodite, are indicated using the same notation as in Figure 1, and
panels A to D correspond with the panels with the same letters in Figure 2, which shows results for changes specific to females or males; as in that figure, differences significant with P < 0.05, after adjusting for multiple testing (
Benjamini and Hochberg 1995) using multiple Wilcoxon tests are indicated by different letters in the figure.
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.
