Recent Developments of Salt and Alkali Tolerance in Soybean
Soil salinization was one of the main factors affecting crop yield,and the improvement and utilization of saline-alkali land was a worldwide problem.In China,saline alkali land was widely distributed and accounts for a relatively high proportion.Soybean was an important economic and oil crop.Developing and utilizing salt alkali tolerant soybean germplasm resources was of great significance for improving soybean salt alkali tolerance,developing soybean industry,and ensuring national food security.This article summarized the harm of salt alkali stress to soybeans,the physiological regulation mechanism of soybean salt alkali tolerance,the exploration and functional research of soybean salt alkali tolerant genes,and the use of biotechnology to improve soybean salt alkali tolerance.It also looked forward to the research direction of salt alkali tolerant soybeans,aiming to provide theoretical and technical support for the cultivation of salt alkali tolerant soybean varieties.
