Sample text

These "chemotypes" usually involve switches within the same pathway of secondary metabolism. For example, polygodial 1 is the main sesquiterpene dialdehyde in some individuals and populations of P. colorata, but other individuals contain almost equal amounts of 1 and 2 (14). Both of these compounds have similar insecticidal activities (13) so this variation may not have adaptive significance for protection against herbivores. However, it is also possible to have presence/absence of a class of bioactive compounds.
