Correlation between RNA-seq samples of Zea mays B73. (A) Experimental approach. (B) Dendrogram of hierarchical clustering analysis for correlation between the samples. (C) Principal Component Analysis (PCA) Plot for pattern discovery. Normalized, trimmed data of the replicates, compared with additional samples of early meiocytes and early anthers. (D) Heatmap of gene expression levels. Log₂ values are coded on the green-to-red scale. Red = high expression level, green = low expression level.
