水稻花发育的分子生物学研究进展

水稻是世界上最重要的粮食作为之一，也是单子叶植物发育生物学研究较理想的模式植物。水稻花器官还是粮食赖以形成的基础。对水稻花发育的研究已开始成为植物分子遗传学的一个新的焦点。近年来有关水稻花发育基因调控的研究已取得了长足的进展，本文从水稻花的诱导、花分生组织的形成和花器官的发育三个方面综述近年来国内外的研究进展。 Abstract:Rice (Oryza sativa L.) is not only one of the most important food crops in the world,but also a model plant for study of molecular developmental biology in monocots.In addition,the rice floral organs provide the basis for grain formation.Study of rice floral development has become a new focus of plant molecular genetics.Recently,notable progress has been made in study of gene regulation in rice floral development.In the review,genetic and molecular mechanisms of floral induction,floral meristem formation,and floral organ development in rice are summarized.

Progress of Molecular Floral Development Research in Rice

Rice (Oryza sativa L.) is not only one of the most important food crops in the world,but also a model plant for study of molecular developmental biology in monocots.In addition,the rice floral organs provide the basis for grain formation.Study of rice floral development has become a new focus of plant molecular genetics.Recently,notable progress has been made in study of gene regulation in rice floral development.In the review,genetic and molecular mechanisms of floral induction,floral meristem formation,and floral organ development in rice are summarized.
