Biosynthesis of Sesquiterpene Lactones in Pyrethrum (Tanacetum cinerariifolium)
Figure 5
Pyrethrum sesquiterpene lactones content in different tissues.
Peak areas of a C7–C8 type sesquiterpene lactone (Grey bars: compound p7 of Figure 4), and of a STL of undetermined structure Black bars: compound p5 of Figure 4) in pyrethrum leaves, stems, ray florets and disk florets relative to the peak areas in disk florets (100%) (A); and in pyrethrum flowers in different developmental stages relative to the peak areas in stage 5 flowers (B). Images of the corresponding pyrethrum flower heads (C) Error bars represent SEM (N = 3).
