Cover image: Close-up of Oryza rufipogon, Asian wild rice, collected from Thailand. Depicted is an individual rice flower, with a yellow anther (upper right) and dark purple pistil (lower left), attached to another flower. The bright red structures are awns, hairlike structures at the tips of the developing seed that aid in dispersal. See the article by Londo et al. on pages 9578–9583.
