PKS Activities and Biosynthesis of Cannabinoids and Flavonoids in Cannabis sativa L. Plants

Abstract

Polyketide synthase (PKS) enzymatic activities were analyzed in crude protein extracts from cannabis plant tissues. Chalcone synthase (CHS, EC 2.3.1.74), stilbene synthase (STS, EC 2.3.1.95), phlorisovalerophenone synthase (VPS, EC 2.3.1.156), isobutyrophenone synthase (BUS) and olivetol synthase activities were detected during the development and growth of glandular trichomes on bracts. Cannabinoid biosynthesis and accumulation take place in these glandular trichomes. In the biosynthesis of the first precursor of cannabinoids, olivetolic acid, a PKS could be involved; however, no activity for an olivetolic acid-forming PKS was detected. Content analyses of cannabinoids and flavonoids, two secondary metabolites present in this plant, from plant tissues revealed differences in their distribution, suggesting a diverse regulatory control for these biosynthetic fluxes in the plant.

Why did you cut and paste this stuff?

its a science sub forum...this is the place to post this stuff..I take it you have no idea what it means

hey storm shadow, actually its a place to discuss this stuff, so if you have a good handle on what you are posting then some kind of explanation or opinions from yourself would probably help get things going. we have a few experts here and many more who are keen to learn (myself being the latter).
