Rice Cyp2 gene for increasing plant salt tolerance

Abstract

The present invention discloses one rice Cyp2 gene for raising plant salt tolerance and possessing the base sequence as shown in SEQ ID No. 1 in the sequence list. One protein related to the salt tolerance of rice is first separated and identified fast by means of the protein group technology based on 2-D electrophoresis and mass spectrography; and the Cyp2 gene is then proved to have the function of raising plant salt tolerance by means of genome and biochemical measures. Transferring the salt tolerance Cyp2 gene to rice, strawberry, flower and other plants can raise their salt tolerance to raise yield and quality.

Description

technical field [0001] The invention relates to functional genomics, in particular to a rice Cyp2 gene for improving plant salt tolerance. 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 agricultural farmland due to salinization has reduced production and abandoned farmland to nearly 500 million mu. In recent years, with the rapid development of my country's facility agriculture, especially the expansion of the production area of ​​vegetable and flower greenhouses, the excessive use of chemical fertilizers in these protected areas has continuously evaporated the water on the soil surface, causing the deep water to move upward through capillary action, resulting in Soil salinity accumulates to the surface layer, aggravating the second...

Problems solved by technology

However, the above-mentioned proteins were only isolated and identified on the level and type of protein expression profiles, and did not provide functional evidence for changing plant salt tolerance
