Abstract

The invention discloses a cold-resistant gene engineering application method of rice OsICE2 gene. The method includes: (1) gene cloning, (2) vector construction, (3) transgenosis, (4) analysis of the cold-resistant phenotype of OsICE2 by a transgenic technology, and (5) comparative analysis of a transgenic plant and a control plant in the cold-resistant physiological aspect. By the steps, the method determines the influence of OsICE2 gene on protein expression quantity under low temperature stress, and finds that a transgenic rice strain can slow down the reduction of protein expression quantity of RuBi sCO subunit binding-protein alpha subunit, RuBi sCO activase small isoform precursor, Chlorophyll a-b binding protein and isocitrate dehydrogenase under low temperature stress, and improves the expression increase range of 70 kDa heat shock-related protein.

Description

technical field [0001] The invention belongs to the technical field of genetic engineering, in particular to a cold-resistant genetic engineering application method of rice OsICE2 gene. Background technique [0002] Chilling injury is an environmental stress factor that has an important impact on crop growth and development. Rice is the main food crop in my country, and it often encounters the problem of chilling injury at the seedling stage, which has a negative impact on rice production. Therefore, it is of great theoretical significance and application value to study the molecular mechanism of cold resistance of crops, especially rice, and to cultivate resistant germplasm. [0003] According to the different degrees of low temperature, the low temperature injury of plants is divided into chilling injury and freezing injury. Chilling injury refers to the obstacle of plant physiological mechanism caused by low temperature above 0 ℃, and freezing injury refers to the obstac...
