Effect of phyB on gene expression in Solanum tuberosum spp. Andígena. A) Volcano plot of log₂ transformed expression ratios (WT/α-PHYB) plotted against the negative log₁₀-transformed p-value from a one-sample t-test. Shaded areas highlight the genes showing a statistically significant difference in gene expression of at least two fold. The numbers indicate the genes present in the shaded area. B) Percentage distribution of functional categories corresponding to genes whose expression was higher in WT compared to α-PHYB plants. C) Percentage distribution of functional categories corresponding to genes whose expression was higher in α-PHYB compared to WT plants.
