The reason for these diversities in plant metabolism is not clear; however, it seems likely that the formation of highly individualized and specialized path978-1-4684-0774-7978-1-4684-0772-3

Therefore, owing to this metabolic versatility, one might expect that alkaloids can be formed in all cells of a plant. This may be the case in some plants, such as .
