De Novo Transcriptome Sequencing of the Orange-Fleshed Sweet Potato and Analysis of Differentially Expressed Genes Related to Carotenoid Biosynthesis

Figure 3

Comparative analysis of gene expression in Weiduoli and HVB-3. (a) A scatter plot of RPKM logarithmic values in libraries of Weiduoli and HVB-3. Each dot represents the RPKM value of a specific gene. The greater deviation from the diagonal slope shows a greater expression level of the gene in the corresponding material. (b) A scatter plot of the ratio of RPKM logarithmic numerical values of genes in Weiduoli and HVB-3. This plot graphically represents genes differentially expressed between Weiduoli and HVB-3. Blue dots represent genes that had significant difference and red dots represent genes where no significant difference was observed between Weiduoli and HVB-3.
