摘要: 根系作为水稻(Oryza sativa)植株的重要组成部分, 在水稻生长发育过程中发挥多种作用, 包括植物的固定、水分和营养物质的获取以及氨基酸和激素的生物合成等, 其形态结构和生理功能与水稻产量和稻米品质以及抗性等密切相关。目前, 通过遗传及生化等诸多手段, 已挖掘到较多水稻根系QTLs与控制基因。该文综述了水稻根系QTL和基因的研究进展, 并对未来根系研究进行展望, 以期为进一步克隆水稻根系基因和完善水稻理想株型模型提供参考。

Abstract: As an important part of rice (Oryza sativa), the root system plays multiple roles in rice growth, including plant fixation, water and nutrients acquisition, amino acid and hormone biosynthesis. Root morphological structure and physiological function are closely related to rice yield and quality, and resistance. So far, many QTLs and genes regulating rice root system have been identified through genetic and biochemical approaches. In this paper, we summarized current progress on the study of rice root system-related QTLs and genes and the future research direction, so as to provide a reference for further screening and cloning root related genes and improving the model of ideal plant architecture of rice.
