Rice protein OsOEE3-1, encoding gene and application thereof

Abstract

The invention provides and discloses a rice salt-resistant protein OsOEE3-1 with amino acid sequence described in a sequence table SEQ ID NO.1. The protein obtains over-expression in rice seedlings and can improve the high-salt-resistance ability and high-temperature-resistance ability of the rice seedlings. If a gene encoding the protein is used for converting Arabidopsis thaliana, pepper, eggplant, strawberry, Salvia splendens, gerbera hybrida and other vegetables and flowers, the high-salt-resistance and the high-temperature resistance performances of the plants are possibly improved, thereby being conductive to increasing the yield of rice or outdoor vegetables and flowers on saline-alkali soil, improving the utilization of the saline-alkali soil in coastal areas of China, overcoming the continuous cropping obstacle caused by soil salinization and high temperature under the facility conditions, improving the yield and the quality of vegetables, flowers and other plants, promoting the agricultural efficiency improvement and increasing the income of farmers.

Description

technical field [0001] The invention relates to the field of functional genomics, in particular to a rice protein OsOEE3-1 and its coding gene and 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...
