水稻的产量由单株穗数、每穗粒数和粒重共同构成,彼此之间相互影响、相互制约。株型是产量的重要决定因子,以“理想株型”为育种目标的遗传改良极大的提高了水稻的产量,但是关于水稻株型建成的分子调控机制目前还不是很清楚。12月2日,《美国国家科学院院刊》(PNAS)在线刊发了华中农业大学
The yield of rice is composed of the number of panicle per plant, the number of grains per panicle and grain weight, which influence each other and restrict each other. Plant type is an important determinant of yield. Genetic improvement with “ideal plant type” as the breeding target greatly improves the yield of rice, but the mechanism of molecular regulation on the establishment of rice plant type is not yet clear.
