Global analysis of transcriptome. a, The number of expressed genes and respective expression levels in each sample based on the FPKM. b, The hierarchical cluster analysis of samples. c, The principal component analysis. The first and second principal components explained 46.2% and 15.1% of variance, respectively. PC1, the first principal component; PC2, the second principal component
