摘要
随着全球气候变暖和人口不断增长,农业用水增加和可利用淡水资源减少使得水稻生产正面临资源与环境的严峻挑战.在众多环境胁迫中,干旱胁迫是影响农业生产的主要因素之一,严重危害水稻的产量和品质.随着分子生物技术的飞速发展,与干旱胁迫相关的水稻数量性状位点、功能基因被不断挖掘.本文综述了水稻抗旱相关QTL的鉴定、克隆以及抗旱分子机理研究等方面的进展,以期为水稻抗旱研究和分子育种提供参考.
Abstract
With the global warming and population growth,the increase of agricultural water and the decrease of available fresh water resources,rice production is facing severe challenges of resources and environment.Among many environmental stresses,drought stress is one of the main factor affecting agricultural production,which seriously harms the yield and quality of rice.With the rapid development of molecular biotechnology,the genes,quantitative trait loci and functional genes related to drought stress are constantly being explored.In this paper,the progress of identification,cloning,molecular mechanisms of drought resistance related QTLs in rice were summarized,and aim to provide valuable information for the further study and molecular breeding of drought resistance in rice.
