- Key message
- Several enzymatic properties of OsCPS2/OsCyc2, including the optimal pH, optimal temperature, divalent cation requirement, and kinetic values for the geranylgeranyl diphosphate (GGDP) substrate, were almost the same as those of OsCPS1
- Specifically, OsCPS1, which encodes an enzyme in the GA biosynthesis pathway, was down-regulated and OsCPS2 and OsCPS4, which encode enzymes in phytoalexin biosynthesis, were up-regulated in gid1
- The rice genome contains two ent-copalyl diphosphate synthase genes: OsCPS1 acts in gibberellin (phytohormone) biosynthesis, and OsCPS2/OsCyc2 acts in the synthesis of oryzalexins A-F and phytocassanes A-E (phytoalexins)
- Furthermore, the OsCPS1 activity exhibited approximately 70% inhibition by 100 muM Amo-1618 (a gibberellin biosynthetic inhibitor), whereas the OsCPS2/OsCyc2 activity exhibited approximately 10% inhibition
- 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
- Rice (Oryza sativa L.) has two ent-CDP synthase genes, OsCPS1 and OsCPS2.
- The results indicate that transcripts of the two ent-CDP synthase genes differentially localize in rice plants according to their distinct biological roles, OsCPS1 for growth and OsCPS2 for defence.
- It has been thought that OsCPS1 participates in GA biosynthesis, while OsCPS2 participates in the biosynthesis of phytoalexins, phytocassanes A-E, and oryzalexins A-F.
