Plant salt-tolerant gene module mining method

Abstract

The invention discloses a plant salt-tolerant gene module mining method. The method comprises the following steps that: based on a gene interaction network, a Markov clustering algorithm is adopted to carry out modular analysis on the gene interaction network, and gene chip and whole genome associated data are utilized to evaluate the salt tolerances of gene modules; and a key salt-tolerant gene module is screened out according to the salt-tolerant contribution of each gene module. Compared with an existing method, the method focuses on discovery of a brand new salt-tolerant gene group, and greatly improve the efficiency and accuracy of plant salt-tolerant gene mining.

Description

technical field

[0001] The invention relates to the technical field of salt-tolerant genes, in particular to a method for discovering plant salt-tolerant gene modules. Background technique

[0002] The salinization of cultivated land is one of the main problems faced by my country's agricultural production at present, which seriously affects my country's agricultural production and food security. Cultivating new varieties of crops that are resistant to salinity is one of the effective means to face salinization. For saline-alkali land improvement is of great significance. The mechanism of plants adapting to saline-alkali environment is very complex, which is the result of the comprehensive regulation of complex networks formed by the interaction of many genes / pathways. After plants are subjected to salt stress, through signal perception and a series of complex signal transduction and activation of specific transcriptional regulatory factors, and then regulate the expression ...
