Fig. 5From: Metabolite profiling and transcriptomic analyses reveal an essential role of UVR8-mediated signal transduction pathway in regulating flavonoid biosynthesis in tea plants (Camellia sinensis) in response to shadingThe shading effects on transcript abundance of potential genes and TFs involved in flavonoid biosynthesis and light signal transductions in tea buds. a The shading effects on transcript abundance of genes and potential TFs involved in the flavonoid biosynthetic pathway. b The shading effects on transcript abundance of potential genes and TFs involved in the UVR8-mediated UV-B, UV-A/blue light and red/far-red light signal transduction pathways, respectively. c Cluster analysis of expression of all potential genes and TFs in response to shading treatment. The heatmaps are constructed from the competitive expression of genes (log2 FPKMS80–90%/FPKMcontrol) from the transcriptome datasets. S 4h, S 8h, S 2d, S 8d and S 14d indicate time points at 4h, 8h, 2d, 8d and 14d throughout shading period. The triangle with colors represents potential genes involved in the flavonoid biosynthetic pathway (functional enzymes, yellow; TFs, green) and different light transduction pathways (UV-B radiation, purple; UV-A/blue light, blue; red/far-red light, red; genes and TFs involved in three light signal transduction, black). Data shown are the average mean of three biological replicates (n = 3). *Significant differences comparing the Control treatment at each time point according to one-way ANOVA and a Fisher’s LSD test at the 5% level (*p < 0.05, **p < 0.01; fold change ≥2)Back to article page
