Using the combined analysis of transcripts and metabolites to propose key genes for differential terpene accumulation across two regions

ABSTRACT: To obtain an interpretation from the view of transcriptome on distinct metabolite accumulation between ecologically different regions in China, next-generation sequencing technology was performed on E-L 31, 35?36 and 38 stages of Muscat Blanc a Petits Grains grape berries from Changli (CL, eastern) and Gaotai (GT, western). Transcriptome analysis revealed that some key genes involved in terpene synthesis were markedly up-regulated in the CL region. Particularly in the MEP pathway, the expression of VvHDR (1-hydroxy-2-methyl-2-butenyl 4-diphosphate reductase) paralleled with the accumulation of terpenes, which can promote the flow of isopentenyl diphosphate (IPP) into the terpene synthetic pathway. The glycosidically bound monoterpenes accumulated differentially along with maturation in bot
