Rice OsC2DP gene and role thereof in rice salt stress

Abstract

The invention belongs to the technical field of plant genetic engineering, and particularly relates to a rice OsC2DP gene and a role thereof in rice salt stress. The sequence of the gene is shown in SEQ ID NO. 1. The rice OsC2DP gene is mainly expressed in roots and is inhibited by Na<+>; and the analysis results of subcellular localization show that the rice OsC2DP gene is mainly localized in cytoplasm. The role of the OsC2DP gene in rice salt stress is mainly described. The OsC2DP can be used as a salt-tolerant gene and plays an important role in the tolerance of rice to salt stress.

Description

technical field [0001] The invention belongs to the technical field of plant genetic engineering, and specifically relates to a rice OsC2DP gene and its function in rice salt stress. Background technique [0002] In recent years, abiotic stress has become an increasingly serious environmental problem. The growth of crops is often subjected to various abiotic stresses in the environment, such as drought, cold, heavy metal pollution, salt stress, etc., which may inhibit their growth and affect crops. Production losses are severe. Salt stress is one of the most destructive stresses to rice. Salt stress can lead to the decrease of photosynthetic rate, stomatal conductance, transpiration rate and so on. At present, about 20% of the world's cultivated land and nearly half of the irrigated land are affected by soil salinity. The area of ​​saline-alkali land in the world is 960 million square meters, and it is growing at a rate of 100,000-150,000 square meters per year. Agricultu...

Problems solved by technology

Therefore, studying different strategies to make rice plants more salt-tolerant and increase their productivity in saline-alkaline soils is an important challenge for researchers to deal with the reduction in grain production caused by soil salinization.
