Method for constructing photosynthetic pathway gene regulation network

Abstract

The invention provides a method for constructing a photosynthetic pathway gene regulation network. The method comprises the following steps of 1) obtaining SNP data of photosynthetic pathway genes of species; 2) measuring phenotypic traits of the species to obtain phenotypic data; 3) performing inter-genetic locus epistasis mode detection by utilizing the SNP data obtained in the step 1) and the phenotypic data obtained in the step 2), and determining an interaction relationship between every two genes; 4) verifying the correlation among the genes obtained in the step 3); and 5) constructing the gene regulation network by taking the correlative genes obtained in the step 3) as candidate genes, wherein the step 1) and the step 2) are free from time sequence limitation. According to the construction method provided by the invention, genetic locus mutation and biotic population phenotypes are comprehensively considered; the gene regulation network is constructed more accurately by calculating inter-locus epistasis; and the method has important theoretical significances and practical values for research and improvement of a photosynthesis mechanism.

Description

technical field [0001] The invention relates to the technical field of gene regulation network, in particular to a method for constructing a photosynthetic pathway gene regulation network. Background technique [0002] Photosynthesis is one of the most important chemical reactions in the world. More than 90% of the biomass energy and wood tissue on the earth come from photosynthesis, but the efficiency of photosynthesis is low, and only 2% to 4% of solar energy can be used. Therefore, we are committed to It is particularly important for the improvement of photosynthesis. However, photosynthesis involves a series of complex biological processes, and its regulatory relationship is complicated. Only by improving the photosynthetic rate through traditional methods, its effect is limited. Photosynthesis is a complex process that is regulated by multiple levels and multiple genes, and it cannot be regulated by the study of single genes alone. Gene regulatory network embodies the...
