Figure 5From: Transcriptome analysis reveals in vitro cultured Withania somnifera leaf and root tissues as a promising source for targeted withanolide biosynthesis Expression analysis of selected genes related to withanolide biosynthesis. Adventitious roots and leaves of 30, 45, and 60 days old were collected and their total RNAs were used for qRT-PCR analysis of genes for HMGR, FPPS, SE, CAS, and GT. Relative expression levels were calculated by the 2-ΔΔCt method with GAPDH as an internal control.Back to article page
