水稻分子发育研究的若干进展

Progress of Molecular Development Research in Rice

水稻是基因组最小的禾谷类作物 ,也是植物发育生物学和分子生物学研究较理想的模式植物。水稻分子发育的研究正成为植物发育生物学研究热点课题 ,从水稻花和花器官的发育、胚胎发生和营养器官——茎发育等三个方面简要介绍了近期研究的有关进展。

Rice (Oryza sativa L.), which has a small genome in cereal plants, has several advantages as a model species for studying molecular biology and developmental biology. Although molecular studies on rice development have just begun, a growing number of investigation materials of molecular development in rice are now being increased. In the review, first, molecular developmental mechanisms of flower and floral organs are summarized. Then, molecular mechanisms of embryogenesis are discussed. At last, recent progress toward molecular process of formation and development of vegetative organ are described.
