I will study pyrrolizidine alkaloid diversity in Jacobaea vulgris, Jacobaea aquatica, their F1 generation and F2 generation plants. In previous work, we have described the pyrrolizidine alkaloid variation in shoots and roots of segregating hybrids between J. vulgris and J. aqutica, the effect of hybridization on secondary metabolites and herbivore resistance. Meanwhile, the interaction between plants and herbivores has partly become elucidated but many questions remain with respect to the role of specialist and generalist herbivores. In addition, all the experiments were done in growth chamber conditions; it is not known how genotype-environment interactions influence PA composition in nature, and whether oviposition and feeding preferences in nature and lab are similar. Therefore, for further study, I will investigate: (1) the seasonal variation pattern of pyrrolizidine alkaloid in J. vugris, J. aqutica and their F1 and F2 plants in the field; (2) the diurnal variation pattern of pyrrolizidine alkaloid in J. vugris, J. aqutica in the natural conditions; (3) whether the pyrrolizidine alkaloids in host plant influence the oviposition preference of cinnabar moths (Tyria jacobaeae); (4) the interaction between pyrrolizidine alkaloids in F2 hybrids and herbivores, such as snail (Helix aspersa), flea beetle (Longitarsus jacobaeae) and beet armyworm (Spodoptera exigua); (5) the pyrrolizidine alkaloids diversity is not only influenced by environment, but also by genetic factors. So what genetic control exists in the Jacobaea plants? I will do quantitative trait compound analysis, if we have mapped our cross.
