摘要
芒是许多禾本科作物穗部的重要结构,不仅可以作为区分不同品种以及基因定位的重要形态标记,而且在禾谷类作物的种子传播、籽粒灌浆、蒸腾作用及产量形成等方面起重要作用。该文综述了小麦(Triticum aestivum)、大麦(Hordeum vulgare)和水稻(Oryza sativa)芒的结构、功能与遗传调控机制研究进展,以期为芒性状遗传机理的进一步研究及其在育种中的应用提供参考。
The awn is an important structure on the panicles of many cereal crops,which can not only be used as an important morphological character to distinguish different varieties and as a morphological marker for genetic mapping,but also play an important role in seed transmission,grain filling,transpiration and yield.Here we summarize the recent advancement of studies on the structure,function and genetic mechanism of the awn in wheat,barley and rice,which may provide a reference for the further studies on the genetic mechanism of the awn development,and for the application in breeding.
