Abstract:

Rice (Oryza sativa), cultivatedin one-third of the world, is one of the most important crops with a long culture history. Cultivated rice is domesticated from wild rice (O. rufipogon). Rice yield is an important domesticated phenotype. Rice yield is controlled by three morphologic features, including tiller characteristics, panicle structure and seed size. These phenotypes were selected from the wild type during domestication and increased yield. In this review, we summarize the molecular mechanism of yield domestication and discuss problems and prospects of rice culture to provide new insights for rice domestication and molecular breeding.
