| 摘 要： | 穗型作为水稻(Oryza sativa)重要的农艺性状,近年来一直是研究热点。该文简要介绍了水稻穗部发育的一般过程,总结了近年来发现的调控水稻穗型相关基因,并根据水稻幼穗发育过程将其分为4类:分别调控枝梗分生组织的形成、枝梗分生组织的大小、小穗分生组织的转变时间以及枝梗的伸长;并概括分析了上述基因在调控水稻幼穗发育过程中所呈现出的路径关系。最后对水稻穗型遗传调控研究的未来发展方向进行了展望。

| Abstract: | Panicle architecture, as a key agronomic trait of rice (Oryza sativa), has been a research hot topic in recent years. In this review, we introduce the general development progress of a rice panicle. Genes related to rice panicles are summarized and are classified into 4 categories according to their function in panicle development: regulating initiation of meristem, meristem size, transition from branch meristem to spikelet meristem and elongation of branches. Furthermore, we summarize emerging networks of genes and pathways. Finally, we discuss the problems and prospects of future research into the genetic regulation of rice panicle. |
