Embodiment 1

[0033] Example 1. Acquisition and functional verification of rice stress-resistance-related proteins and their coding genes

[0034] 1. Acquisition of stress-related proteins and their coding genes in rice

[0035] Through yeast two-hybrid technology, rice stress-related protein TCTP was screened. Yeast two-hybrid system (CLONGTECH company) is a molecular biology method for studying protein-protein interactions. It is based on the fact that transcription factors can be divided into independent regions, namely DNA-binding domains and transcription activation domains, to achieve artificial simulation of transcription natural process. The bait protein used is DREB transcription factor, namely drought response element binding protein, which can specifically bind to the DRE / CRT cis-element in the promoter, activate the expression of many stress-induced genes, and enhance the tolerance of plants to adversity. Screening of proteins interacting with DREB transcription factors by yea...

Abstract

The invention discloses a plant anti-versus relative albumen and the coding gene and the application. The albumen contains one of the following amino acid residue sequences: SEQ ID No:1 in the sequence table; the albumen that take replacement and / or lacking and / or adding one or plural amino acid residue of SEQ ID No:1 in sequence table. The invention could enhance the anti-versus of paddy.

Description

technical field [0001] The invention relates to a plant stress resistance-related protein, its coding gene and application. Background technique [0002] The global arid and semi-arid areas account for about 36% of the total land area and 43% of the cultivated land area. my country's arid and semi-arid regions are mainly distributed in North China, Northwest China, Inner Mongolia and the Qinghai-Tibet Plateau, accounting for about half of the country's land area. With the increase of population, social and economic development and changes in natural climate conditions, the shortage of water resources has become increasingly serious, seriously affecting agricultural production. Drought stress often affects plant growth and development, resulting in severe crop yield reduction. The loss of crops caused by drought ranks first among all abiotic stresses, second only to the losses caused by biotic stresses, diseases and insect pests. In order to solve these problems, research ...
