Hong-Xuan Lin and colleagues report that the gene PROG1 has an important role in determining the architecture of wild rice, including tiller angle and number of tillers. PROG1 encodes a zinc-finger transcription factor, and the authors suggest that selection of an amino acid substitution in PROG1 during domestication facilitated the transition to the architecture of domesticated rice.
