Fig. 6From: Transcriptome profiling of genes related to light-induced anthocyanin biosynthesis in eggplant (Solanum melongena L.) before purple color becomes evidentHeat map representation of the genes expression patterns. a The structural anthocyanin biosynthesis genes, b All the transcription factors response to light, c The photoreceptors and genes related to light signal transduction. The color scale represents the Log2 (fold-change to the 0Â h time point). Genes that are upregulated appear in yellow, and those that are downregulated appear in blue, with the relative Log2Ratio reflected by the intensity of the colorBack to article page
