Fig. 3From: Molecular identification and expression of sesquiterpene pathway genes responsible for patchoulol biosynthesis and regulation in Pogostemon cablinGC ± MS analysis of patchoulol in P. cablin. a Mass spectra at the retention time of patchoulol. Arrowheads indicate the retention time of patchoulol. b The accumulation of patchoulol in P. cablin. Student’s t-test was performed to identify significant differences. One asterisk (*) indicates a significant difference (0.01 < P < 0.05)Back to article page
