Cloning and characterization of cDNAs encoding ent-copalyl diphosphate synthases in wheat: insight into the evolution of rice phytoalexin biosynthetic genes

Biosci Biotechnol Biochem. 2009 Mar 23;73(3):772-5. doi: 10.1271/bbb.80781. Epub 2009 Mar 7.


In vitro assays using recombinant enzymes enabled three cDNAs encoding ent-copalyl diphosphate synthases to be identified in wheat (Triticum aestivum): TaCPS1, TaCPS2, and TaCPS3. The phylogenetic tree and expression analyses suggest that TaCPS3 is responsible for gibberellin biosynthesis, while TaCPS1 and TaCPS2 are possible functional homologs of diterpene cyclase genes OsCPS2 and OsCPS4 involved in phytoalexin biosynthesis in rice.
