Application of soybean proteins and encoding gene thereof, primer, expression vector and preparation method

The invention discloses application of soybean proteins and an encoding gene thereof, a primer, an expression vector and a preparation method. The soybean proteins or the encoding gene thereof are used for improving the salt resistance of plants or escherichia coli. The encoding gene of the soybean proteins is Glymallg07260.1. The soybean proteins can enhance the salt resistance of the escherichia coli; as multiple resistant genes have similar resistant functions to the escherichia coli and a plant system, the soybean proteins and the encoding gene thereof have a potential application prospect in the plant resistance field. 本发明公开种大豆蛋白及其编码基因的应用及引物、表达载体和制备方法，将所述大豆蛋白或其编码基因用于提高植物或大肠杆菌的耐盐性。其中，所述大豆蛋白的基因编码为Glyma11g07260.1。该大豆蛋白可增强大肠杆菌的耐盐性，由于很多抗逆基因在大肠杆菌和植物体系具有相似的抗逆功能，因此，该大豆蛋白及其编码基因在植物抗逆领域具有潜在的应用前景。
