摘要: Dragon's blood is a traditional medicine widely used in the world, and the main components of which are fiavonoids. However, little is known about its formation mechanism. Previous studies indicate that plant glutathione S-transferase (GST) genes are involved in transportation of fiavonoids from cytosolic synthesis to vacuolar accumulation. In this study, 20 Dracaena cambodiana GST genes (DcGSTs) were identified based on transcriptome database. Phylogenetic analysis revealed that 20 DcGSTs belonged to seven different classes. Tissue-specific expression analysis suggested that DcGSTs displayed differential expressions either in their transcript abundance or expression patterns under normal growth conditions. The transcript profiles of three DcGSTs in response to the inducer of dragon's blood were strongly correlated with fiavonoids biosynthetic genes, consistent with dragon's blood accumulation. Our survey provides useful information for future studies on GST genes involved in dragon's blood formation in D. cambodiana. (C) 2016 Elsevier Masson SAS. All rights reserved.
