selection of self-pollinated plants for artemisin biosynthesis. Selfpollinated F2 plants selected are grown under optimized growth conditions. The leaves on the main stems exhibit obvious morphological changes, from indented single leaves to odd, pinnately compound leaves. Leaves and flowers form glandular and T-shaped trichomes on their surfaces. The glandular trichome densities increases from the bottom to the top leaves. Leaves, flowers, and young seedlings of F2 plants produce artemisinin. In leaves, the levels of artemisinin increase from the bottom to the top of the plants, showing a positive correlation to the density increase of glandular trichomes. Progeny of selfpollinated plants expresses the amorpha-4, 11-diene synthase and cytochrome P450 monooxygenase 71 AV1genes, which are involved in artemisinin biosynthesis in leaves and flowers |
