Overview of mRNA Expression Profiles at Different Stages of Internode Elongation in Sugarcane. a Heat map comparison of the pre-elongation stage (EI), early elongation stage (EII) and rapid elongation stage (EIII). The Z-score calculated from RPKM values for each gene were used. Gene expression is colored for low (blue) to high (red). Each line represents a single gene and each row shows a library listed on the left. b Two-component principal component analysis of the nine transcriptomes from the pre-elongation stage (EI), early elongation stage (EII) and rapid elongation stage (EIII). The percentages represent the variances captured by the principal component 1 (PC1) and principal component 2 (PC2). Red, blue and green dots indicate EI, EII and EIII, respectively
