Expression and co-expression network analysis of CsbZIP genes under abiotic stress. a Heat map of all CsbZIP genes under different abiotic stresses based on transcriptome datasets. The expression values (FPKM) were normalized. b Venn diagram showing the overlap of differentially expressed CsbZIP genes under abiotic stress. The letters on the line and below the line indicate the differentially expressed CsbZIP gene numbers in the shoots and roots, respectively. c Co-expression network of the CsbZIP genes with DEGs under abiotic stress. The grey lines between two nodes indicate co-expression relationships. The purple solid circles represent overlapping genes. d Venn diagram showing the overlap of differentially expressed CsbZIP genes under abiotic stress and ABA stress. H: heat stress; C: cold stress; LS: light salt stress; MS: moderate salt stress; SS: severe salt stress; LDS: light drought stress; SDS: severe drought stress; RE: recovery
