Fig. 2From: Using the combined analysis of transcripts and metabolites to propose key genes for differential terpene accumulation across two regionsChange of total concentrations of free and glycosidically-bound volatiles. Columns indicate mean concentration (n = 3), and bars indicate standard error of the mean. Pound sign and asterisk represent significant difference of free and glycosidically-bound data between CL and GT region, respectively (p < 0.05). CL and GT is the abbreviation of Changli and GaotaiBack to article page
