System Perspective Analysis for Molecular and Genetic Source of Salt Tolerance in Cotton

Abstract

Sources of tolerance salinity stress in plants are the results of sets of the simple effect and interaction among genes. A systematic perspective at the polygenic trait process of resistance to environmental stresses, including salinity stress, and the interactions among genes and their inheritance, may provide new insights into the process of integrating beneficial genes into genotypes. In this study, we aimed interaction of candidate genes include NHX1, TPS1, ERF2, SOD, CIPK, PP2C. Salinity was selected and their correlation was calculated using their pathway. The results showed that the effect of antioxidant gene alignment including SOD, the most direct effect and the genes most effective in regulating sodium / potassium channels and antiporters were the second most effective factor. The relationship between these two groups of genes and their protein activity was positive and highly significant (Pvalue <0.001). This result showed that, strengthening of antioxidant systems in cotton either directly or indirectly through environmental induction or through trans activators can be effective in salt stress tolerance of genotypes. If we ignore the effects of environmental induction regulated by agro-ecophysiological conditions, most transcriptional factors study focused on ERF1. It was through binding to CIS elements that were effective in resisting to salt stress.
