摘要
水稻是世界上最重要的粮食作物之一,也是单子叶植物分子生物学研究的模式植物。稻穗(即花序)的生殖发育直接影响到稻谷的产量和稻米的品质,因此研究水稻花器官的形成无论在发育生物学还是在遗传育种上都具有重要的理论意义和实际应用价值。本文介绍了当前花器官研究状况,从簇生穗的性状,形成机制及遗传学分析等方面的出发,阐述了簇生穗基因的研究进展,并展望基因在未来水稻遗传育种中的应用。
Rice ( Oryz a sativa L .) is one of the most important crops in the world ,and also a model plant for molecular biology research in monocotyledon . Rice reproductive development directly affects yields and quality of rice . Therefore ,researches on rice floral organ development showed great theoretical significance and practical application for both molecular developmental biology and rice genetics and breeding . In this review ,the research progress of floral organ development was introduced . Meanwhile ,the research status of Cl gene and the prospective of application of the gene were elucidated on the basis of traits of rice clustered spikelets ,formation mechanism and genetic analysis .
