主 题:Arabidopsis geranylfarnesyl diphosphate synthase geranylgeranyl pyrophosphate synthase plastid sesterterpene terpene network
摘 要:Terpenes are the largest and most diverse class of plant specialized ***(C25),which are derived from the plastid methylerythritol phosphate pathway,were recently characterized in *** Arabidopsis thaliana,four genes encoding geranylfarnesyl diphosphate synthase(GFPPS)(AtGFPPS1 to 4)are responsible for the production of GFPP,which is the common precursor for sesterterpene ***,the interplay between sesterterpenes and other known terpenes remain ***,we first provide genetic evidence to demonstrate that GFPPSs are responsible for sesterterpene production in *** of the sesterterpene pathway at the GFPPS step increased the production of geranylgeranyl diphosphate(GGPP)-derived ***,co-expression of sester TPSs in GFPPSOE(overexpression)plants rescued the phenotypic changes of GFPPS-OE plants by restoring the endogenous *** further demonstrated that,in addition to precursor(DMAPP/IPP)competition by GFPPS and GGPP synthase(GGPPS)in plastids,GFPPS directly decreased the activity of GGPPS through protein-protein interaction,ultimately leading to GGPP deficiency in *** study provides a new regulatory mechanism of the plastidial terpenoid network in plant cells.
