A QTL for rice grain width and weight encodes a previously unknown RING-type E3 ubiquitin ligase : A
Map-based cloning of the GW2 QTL We chose parental varieties that showed highly significant differences in grain size to more easily identify the QTL. We crossed a Japonica variety, WY3, with a very large grain (1,000-grain weight, 41.9 g 1.3 g) and a hig...
