The expression pattern of BBX genes based on log2-transformed FPKM values in three treatments. a Heatmap based on gene expression in different tissues at different stages in S. spontaneum and S. officinarum.b Heatmap based on gene expression across leaf gradients in S. spontaneum and S. officinarum. c&d) Heatmap based on gene expression during the diurnal cycles in S. spontaneum and S. officinarum. The heat map was plotted with the TBtools software (v1.098). Expression values were normalized to genes based on the average linkage algorithm. The scale bar represents the log2 normalized expression. Red indicates higher expression while blue indicates lower expression
