Multivariate analyses of RNA-Seq data obtained from Santa Rosa (SR) and Sweet Miriam (SM) cultivars at two developmental stages (S2 and S4-II). (A) Principal component analysis (PCA) resulting from the expression values of 17 721 genes in each one of the three biological replicates for SR and SM cultivars at S2 and S4-II stages in the RNA-Seq data set. Scores of principal component 1 (x-axis) and 2 (y-axis) explained 41.8% and 18.5% of total variance, respectively. (B) Cluster dendogram obtained from the mean gene expression level of three biological replicates in each cultivar–stage combination (SRS2, SRS4-II, SMS2, and SMS4-II), from RNA-Seq data.
