Clustering model analysis of DEGs. a: The 16 clustering modules, in which S0, S6 and S24 indicate the DEGs of alkaline-sensitive genotype AM-314/MS-155 under alkaline salt stress for 0, 6 and 24 h, while T0, T6 and T24 denote the DEGs of alkaline-tolerant genotype Alamo under alkaline-salt stress for 0, 6 and 24 h. b: Clustering of the mainstream genes. c: The changing trend of the mainstream genes of two genotypes with stress time
