Aphelandra squarrosa and Lamium galeobdolon (IMAGE)
Caption
Benzoxazinoids are produced in very different plants, such as the zebra plant Aphelandra squarrosa (left), the golden dead-nettle Lamium galeobdolon (right) and maize. Comparative studies of the plant metabolites and the genes expressed have now demonstrated how flexible plant metabolism is. The formation of benzoxazinoids in the three species is based on different enzyme classes and has thus evolved independently of one another.
