The accumulation profiles of astringent compounds and the expression patterns of three CsUGT genes in various organs. (A) The quantitative analysis of βG, EGCG, ECG, rutin, F-glycosides (Glc), and F-glycosides (Gal) in different organs. Levels of total F-glycosides (Glc) include kaempferol 3-O-glucoside, quercetin 3-O-glucoside, myricetin 3-O-glucoside, kaempferol 3-O-rhamnosyl-(1→6)-glucoside, kaempferol 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-glucoside], quercetin 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-glucoside], myricetin 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-glucoside]. Levels of total F-glycosides (Gal) include kaempferol 3-O-galactoside, quercetin 3-O-galactoside, myricetin 3-O-galactoside, kaempferol 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-galactoside], quercetin 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-galactoside], and myricetin 3-O-[glucosyl-(1→3)-O-rhamnosyl-(1→6)-O-galactoside]. (B) The expression profiles of the CsUGT84A22, CsUGT78A14, and CsUGT78A15 genes in different organs. All data points are the means of three biological replicates and each error bar indicates the SD. Labelled columns not connected by the same letter are significantly different at P <0.05, based on Tukey’s honestly significant difference test.
