摘　　要：盐害会对植物生长造成严重的危害、对农作物的产品品质和产量造成很大的损失。通过调控耐盐相关基因的表达,能提高转基因植物的耐盐能力。近年来,人们克隆了许多与耐盐相关的基因,主要包括渗透调节物合成基因、耐盐相关蛋白类基因、保护酶相关基因、转录因子的调控基因。主要综述了近年来植物耐盐相关基因的克隆及其在棉花基因工程中的研究应用等方面的一些进展,并对棉花耐盐基因工程的研究应用提出了对策和展望。Salinity stress affects plants growth and crop product quality and causes the loss of crop yield. Plant salt tolerance could be significantly improved through the regulation of salt-tolerant gene expression. In recent years, a number of genes related to salt tolerance, such as osmotic stress-responsive gene, proteins gene, toxicity degrading enzyme gene, transcription factors and non-protein-coding RNA have been cloned. We summarized the research progress of plant salt tolerance in recent years, which included gene cloning,functional verification and its applications of cotton. Accordingly, we also made some suggestion on application of salt tolerant of cotton genetic engineering.
