Arabidopis thaliana salt tolerance gene SRAT1 and uses thereof

Abstract

The invention provides and discloses an Arabidopsis thaliana salt-tolerant gene SRAT1, which has the base sequence described in SEQ ID NO.1 in the sequence listing. Transforming the Arabidopsis thaliana salt-tolerant gene SRAT1 into the model plant Arabidopsis can improve the salt tolerance of Arabidopsis seedlings. If the Arabidopsis salt-tolerant gene SRAT1 is transformed into plants such as rice or strawberry and other vegetables and flowers, it is possible to improve the salt tolerance of plants. Utilization of saline-alkali land; on the other hand, it can overcome continuous cropping obstacles caused by soil back-salt under facility conditions, improve the yield and quality of vegetables, flowers and other plants, and increase farmers' income.

Description

technical field [0001] The invention relates to the field of functional genomics, in particular to an Arabidopsis salt-tolerant gene SRAT1 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.
