摘　　要：大豆(Glycine max(L.)Merill)是植物蛋白质和油脂的重要来源。盐胁迫是造成大豆产量损失的主要非生物胁迫因素。耐盐基因的挖掘对培育大豆耐盐品种至关重要。本文一方面总结了通过正向遗传学获得的大豆耐盐相关数量性状位点或基因,如萌发期耐盐性主效基因GmCDF1(Glyma.08g102000)、2个出苗期QTL(分别位于6号和14号染色体);苗期耐盐性主效基因GmSALT3(Glyma03g32900)以及位于G连锁群的QTL。随着对大豆耐盐性研究的不断深入,目前认为大豆萌发期、出苗期、苗期的耐盐性无直接相关性。另一方面总结了通过反向遗传学途径获得的参与离子运输、转录调控等耐盐性基因,以及通过生物工程技术转入外源基因提高大豆耐盐性的研究进展,期望为解析大豆耐盐分子机制和耐盐育种提供参考。Soybean [Glycine max(L.) Merill] is important source of plant protein and oil. Salt stress causes yield loss which is a major abiotic stress to soybean. Identification of salt tolerant genes is important for breeding salt tolerant soybean varieties. This paper summarized salt-tolerance related quantitative trait loci and genes obtained through forward genetics, including GmCDF1(Glyma. 08G102000, a major gene identified at germination stage), 2 QTLs identified at emergence stage(located on chromosome 6 and chromosome 14 respectively), major gene GmSALT3(Glyma03g32900) and the QTL in G-linked group at seedling stage. Thus it was believed that no direct correlation between salt tolerances to soybean at different growth stages. The paper also summarized research progress of improving salt tolerance of soybean by reverse genetics, such as ion transport, transcriptional regulation and the development of improving salt-tolerance by transferring exogenous genes. It is expected to provide references for analyzing molecular mechanism of salt tolerance and for soybean breeding.
