Fig. 1From: Using the combined analysis of transcripts and metabolites to propose key genes for differential terpene accumulation across two regionsSampling stages (a), titratable acidity (b), Brix (c), in the grapes at four developmental stages in two regions. Asterisk represents significant difference in Brix and titratable acid concentrations between CL and GT region at the EL38 stage (p < 0.05)Back to article page
