PROG1(PROSTRATE GROWTH 1),a semi-dominant gene controls aspects of wild-rice plant architecture, including tiller angle and number of tillers. Function prog1 variants identified in O. sativa disrupt the prog1 function and inactivate prog1 expression, leading to erect growth, greater grain number and higher grain yield in cultivated rice. Sequence comparison shows that 182 varieties of cultivated rice, including 87 indica and 95 japonica cultivars from 17 countries, carry identical mutations in the prog1 coding region that may have become fixed during rice domestication. Location PROG1 (PROSTRATE GROWTH 1), on chromosome 7 that encodes a single Cys2-His2 zinc-finger protein. Expression PROG1 is predominantly expressed in the axillary meristems, the site of tiller bud formation. Rice transformation experiments demonstrate that artificial selection of an amino acid substitution in the PROG1 protein during domestication led to the transition from the plant architecture of wild rice to that of domesticated rice. references: 1.
