Floral traits underlying mating system differentiation in the wind-pollinated sister species <i>Oryza rufipogon</i> and <i>Oryza nivara</i>.

ABSTRACT: The shift from outcrossing to predominantly selfing is one of the most common transitions in plant evolution. This evolutionary shift has received considerable attention from biologists; however, this work has almost exclusively been focused on animal-pollinated systems. Despite the seminal ecological and economic importance of wind-pollinated species, the mechanisms controlling the degree of outcrossing in wind-pollinated taxa remain poorly understood. As a first step toward addressing this issue, we have conducted a comparative study of floral biology between two recently diverged sister species, Oryza rufipogon and Oryza nivara (Poaceae), that are wind-pollinated and possess distinct mating systems with O. rufipogon being outcrossing and O. nivara highly self
