(a) Gene co-expression network. The co-expression network was generated by assigning edges using Pearson’s correlation coefficient for the common DEGs from both leaves and SAMs under long-day conditions. Nodes represent gene names and an edge between two nodes (genes) represents co-expression of the genes. The colours of the nodes represent different functional profiles. Light grey nodes represent photoperiod association, while blue nodes represent biotic stress association. Similarly, dark brown nodes represent abiotic stress association. (b) Relative expression ratios between HZ4 and its NIL for some co-expressed genes in the network in leaves (L) and SAMs (S) after drought (D) and high temperature (HT) treatment under long-day conditions. The relative expression ratio = (relative expression of NIL − relative expression of HZ4)/relative expression of HZ4
