Abstract
Pyrrolizidine alkaloids (PAs) represent a class of typical SMs, which are
constitutively formed in plants containing them and mediating plant-herbivore
interactions. More than 400 PAs have been identified from approximately 6000
angiosperm species. Great diversity of PAs was found in many plants, especially
in Jacobaea and Senecio plants. Leaf-tissue PA variation was found between
plant species, individual plants of the same species, and even among different
organs within one plant. This variation was determined by genetics, but also
influenced by environmental factors. A few studies have been conducted to
investigate the leaf-surface PA variations. According to the previous work on
J. vulgaris plants and the Jacobaea hybrid plants, leaf-surface and leaf-tissue
