and Joseph Williams propose a novel evolutionary and developmental perspective on the structural diversity of female gametophytes in angiosperms.

In the first article of the section Mating Patterns and Gender Strategies, Boris Igic, Russell Lande, and Joshua Kohn examine the breakdown of self-incompatibilitythe principal and most effective mechanism preventing self-fertilizationand its evolutionary consequences. In the second article, Stephen Wright, Rob Ness, John Paul Foxe, and Spencer Barrett pick up on the theme and review the genomic consequences of selfing and outcrossing and preview future developments in the field, as the wealth of new data becomes available. Daniel Schoen and Jeremiah Busch use a novel metapopulation perspective in their discussion of the importance of group-level selection of mating systems. The final two articles in the sectionthe first by John Pannell, Marcel Dorken, Benoit Pujol, and Regina Berjano; the second by Andrea Case, Sean Graham, Terence Macfarlane, and Spencer Barrettconsider transitions in gender strategies in specific groups with exceptional sexual system diversity.

In the final section, Asexual Reproduction and Polypoidy, Jonathan Silverton begins by evaluating the costs and benefits of asexual and sexual reproduction in plant species that have both reproductive modes. His article is followed by Jeannette Whitton, Christopher Sears, Eric Baack, and Sarah Otto's comprehensive review of the evolution of apomixis, or asexual reproduction without fertilization. Next, Stacey Lee Thompson, Gina Choe, Kermit Ritland, and Jeanette Whitton employ new approaches to investigate the presence and extent of asexuality and recombination within populations of the Easter Daisy (Townsendia hookeri). In the final article, Brian Husband, Barbara Ozimec, Sara Martin, and Lisa Pollock synthesize two themes from earlier articlespolyploidy and mating systems. In the course of their study, they find that the costs of se
