Sandstrom P, Ginzel MD, Bearfield JC, Welch WH, Blomquist GJ, Tittiger C: Myrcene hydroxylases do not determine enantiomeric composition of pheromonal ipsdienol in Ips spp. J Chem Ecol. 2008 Dec;34(12):1584-92. Epub 2008 Nov 26.
Myrcene (7-methyl-3-methylene-1,6-octadiene) hydroxylation is likely one of the final reactions involved in the production of the Ips spp. (Coleoptera: Scolytidae) aggregation pheromone components, ipsdienol (2-methyl-6-methylene-2,7-octadien-4-ol) and ipsenol (2-methyl-6-methylene-7-octen-4-ol).
To gain insight into the evolution of pheromone production, we isolated a full-length cDNA from the pinyon ips, Ips confusus (LeConte), that encodes a pheromone-biosynthetic cytochrome P450, I. confusus CYP9T1 (IcCYP9T1). |
