Biochemistry of how plants resist insect attack determined [Registered]

Many plants, release volatiles in response to insect attack. The chemical compounds can be a defense or can be an aromatic call for help to attract enemies of the attacking insect. Researchers from Virginia Tech, Michigan State University, and Georg-August-University Göttingen have discovered how plants produce the defensive compounds. The research is reported in the online early edition (15-19 November 2010) of the Proceedings of the National Academy of Sciences. The article, “Herbivore-induced and floral homoterpene volatiles are biosynthesized by a single P450 enzyme (CYP82G1) in Arabidopsis,” is by Sungbeom Lee, postdoctoral associate in biological sciences in the College of…
