Correlation analysis and principal component analysis (PCA) of all transcripts and expressed genes in the genome. a Correlation analysis of expressed genes among three biological replicates of different samples from different treatments. The dot indicates one biological replicate, and the scale bar represents Spearman’s correlation coefficient. b PCA plot of all transcriptome results. The first and second PCs explained 45.94% and 31.51% variance, respectively. c Expressed gene numbers in the A, B, and D subgenomes of different samples from different treatments. d The flower plot displays all expressed gene numbers (in the center) among all samples and genes specifically expressed in the petals at different time points
