Abstract

The invention discloses identification and an application of a cotton drought-resistance related gene GhDRP1. The invention provides the novel gene GhDRP1 from a cotton PP2C protein phosphatase family, and the expression of the gene is induced in the case of cotton drought stress. A gene sequence of the GhDRP1 consists of 3 introns and 4 exons. A gene coding region of the GhDRP1 is 1254bp long, and a protein containing 417 amino acids is encoded. The GhDRP1 protein is located in a cell nucleus. In the case of the cotton drought stress, the gene expression is obviously increased, showing that the gene is a drought inducing gene. Experiments show that the drought resistance of cotton can be weakened through the over-expression of the GhDRP1, and the drought resistance of the cotton can be enhanced by inhibiting the expression of the GhDRP1. In conclusion, the invention provides the functional gene which has an important application value in improving the drought resistance of the cotton.

Description

[0001] Technical field:

[0002] The invention relates to the cloning and functional identification of a cotton drought resistance related gene GhDRP1.

[0003] Background technique:

[0004] Plant growth and development are closely related to the natural environment. Drought, floods, heat, frost, salinity, pests, weeds, etc. will have adverse effects on plant growth and development, often seriously affecting the yield and quality of crops (such as rice, wheat, cotton, etc.), and some data show that 50% of the The reduction in crop yield is all caused by abiotic stress. Water plays a huge role in the life activities of plants, and any solute must be dissolved in water before it can be absorbed and utilized. It is estimated that more than half of the crop production reduction caused by adverse environmental factors in the world is caused by drought and water shortage.

[0005] Cotton is the most important fiber crop in the world. It belongs to the Malvaceae genus Gossypium and...
