Abstract：
As one of the most important food crops in the world, rice yield is directly related to national food security. Lodging is one of the most important factors restricting rice production, and the cultivation of rice varieties with lodging resistance is of great significance in rice breeding. The lodging resistance of rice is directly related to the mechanical strength of the stalks. In this paper, we reviewed the cell wall structure, its components, and its genetic regulatory mechanism, which improved the regulatory network of rice stalk mechanical strength. Meanwhile, we analyzed the new progress in genetic breeding and put forward some scientific problems that need to be solved in this field in order to provide theoretical support for the improvement and application of rice breeding.
摘要：
作为世界上最重要的粮食作物之一，水稻产量直接关系到国家粮食安全。倒伏是制约水稻生产的重要因素之一,抗倒伏水稻品种的培育在水稻育种中具有重要意义。水稻的抗倒伏性直接关系到秸秆的机械强度。在本文中,我们回顾了细胞壁结构，其组成部分,及其遗传调控机制，提高了水稻秸秆机械强度的调控网络。同时,我们分析了遗传育种的新进展，并提出了该领域需要解决的一些科学问题，以期为水稻育种的改进和应用提供理论支持。
