Arabidopsis thaliana salt-tolerance gene SRAT2 and uses thereof

Abstract

The invention provides a salt tolerant gene SRAT2 in arabidopsis thaliana, which has the base sequence stated in the sequence table SEQ ID No.1. A model plant arabidopsis thaliana is transformed by the salt tolerant gene SRAT2 in arabidopsis thaliana, so the salt tolerance in the arabidopsis thaliana seedling can be improved. If vegetables and flowers such as rice and strawberries are transformed by the salt tolerant gene SRAT2 in arabidopsis thaliana, the salt tolerance in the plants can be improved. On one hand, the yield of rice, outdoor vegetables and flowers in saline-alkali land can be improved and the application of the saline-alkali land in coastal areas of China can be improved; on the other hand, an obstacle of continuous cropping caused by soil salinization under the equipment condition can be overcome, so the yield and quality of plants such as vegetables and flowers are improved and the income of farmers is increased.

Description

technical field [0001] The invention relates to the field of functional genomics, in particular to an Arabidopsis salt-tolerant gene SRAT2 and its application. Background technique [0002] The threat of soil salinization to agriculture is a global problem. There are a total of 1 billion hectares of saline-alkali land in the world, accounting for about 7.6% of the world's land area. my country's saline-alkali land is nearly 100 million hectares, and nearly 3.335 million hectares of agricultural land has been reduced or abandoned due to salinization. In recent years, my country's facility agriculture has developed rapidly, especially the production area of ​​vegetable and flower greenhouses has continued to expand. According to statistics, in 2005, the facility cultivation area of ​​vegetables, flowers, melons and fruits in China reached 2.1 million hectares. The development of facility agriculture has played an important role in the adjustment of agricultural production str...

Problems solved by technology

In recent years, genetic engineering methods have been used at home and abroad to introduce genes involved in the synthesis of osmotic adjustment substances and ion regionalization effects into rice, corn, strawberry, tobacco and other crops, and high salt-tolerant crop lines have been obtained, but there is no commercial application yet.
