摘要:

水稻具有悠久的栽培历史, 是重要的粮食作物, 养育了1/3的世界人口。现代栽培稻(Oryza sativa)由野生稻(O. rufipogon)驯化而来, 产量是驯化筛选的关键性状之一。株型、穗型和种子大小是决定水稻产量的重要性状, 这些性状在水稻栽培过程中均受到了定向筛选。该文以水稻产量性状为核心, 综述了株型、穗型和种子大小等性状的驯化分子机理研究进展, 讨论了水稻产量驯化研究中存在的问题, 展望了驯化性状和相关基因的研究前景, 以期为水稻产量相关性状的驯化机理研究和水稻育种工作提供有价值的线索。

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.
