Abstract

The invention provides a protein related to the cold tolerance of plants and an encoding protein and application thereof. The protein is protein of the following (a) or (b): (a) the protein consisting of an amino acid sequence shown in sequence 1 in a sequence table; and (b) the protein which is obtained through the substitution and / or deficiency and / or adding of one or a plurality of amino acid residues of the amino acid sequence of the sequence 1 in the sequence table, can improve the cold tolerance of the plants, and is derived from the (a). The method for cultivating cold-tolerant plants has important theoretical and practical significances on the research of molecular mechanism of the cold tolerance of the plants, the breeding of cold-tolerant species and the molecular breeding of the cold tolerance of the plants, and provides an economical, quick and effective approach for improving the cold tolerance of the plants. The invention has broad application and market prospect in the agricultural field.

Description

technical field

[0001] The invention relates to a protein related to plant cold tolerance, its coding gene and application. Background technique

[0002] Rice is an important food crop, and chilling injury at the germination stage is one of the important factors affecting rice production in the early rice planting areas in the middle and lower reaches of the Yangtze River, the northeast and northwest rice areas, and the one-crop rice area in the Yunnan-Guizhou Plateau. If the rice seedlings suffer from chilling damage during the germination stage, the growth of rice seedlings will be slowed down and the tillers will be reduced. In severe cases, there will even be a large area of ​​stiff seedlings and dead seedlings, which will eventually lead to a significant reduction in rice yield. Rice varieties. Common wild rice is the ancestor of cultivated rice in Asia. During the evolution of wild rice into cultivated rice, through natural selection and artificial selection, the gene...
