A method of mining drought resistance gene modules in plants

Abstract

A method for mining drought-resistant gene modules in plants. The method is based on the gene interaction network, and uses the Markov clustering algorithm to conduct modular analysis on the gene interaction network, and uses gene chip and genome-wide association data to determine the drought-resistance effect of gene modules. to evaluate. According to the drought resistance contribution of each gene module, the key drought resistance gene modules were screened. Compared with existing methods, this method focuses on the discovery of new drought-resistant gene groups, which greatly improves the efficiency and accuracy of plant drought-resistant gene discovery.

Description

technical field

[0001] The invention relates to biotechnology, in particular to a method for discovering plant drought-resistant gene modules. Background technique

[0002] Plants will encounter a variety of natural environments during their growth, and some natural disasters, such as drought, waterlogging, and pests and diseases, often cause a large reduction in crop production. The damage caused by these environmental stresses to agricultural production is worldwide, especially the damage caused by drought is very serious, which can reduce crop yield by 50%-80%. Therefore, improving crop tolerance to drought and water shortage is one of the important goals of agricultural science and technology research. An important means at present is to use drought-resistance-related genes to genetically engineer crops to obtain new varieties of drought-resistant crops.

[0003] The mechanism of plants adapting to drought environment is very complex, which is the result of the compreh...
