The OsOSC12 committed triterpene ester pathway. a GC–MS profiles of the triterpene alcohol fraction of anther (S12) extracts from OsOSC12 mutant and WT plants. The arrow indicates the peaks present in the WT and the “silent” mutants, but absent in the loss-of-function mutants. Standard, purified poaceatapetol. EIC 189, extracted ion chromatograms at m/z 189. The arrow indicates the poaceatapetol peak. b GC–MS profiles of the triterpene esters of anther (S12) extraction from OsOSC12 mutant and WT plants. 1: poaceatapetol palmitic acid (16:0) ester; 2: poaceatapetol oleic acid (18:1) ester; 3: poaceatapetol stearic acid (18:0) ester; EIC 189, extracted ion chromatograms at m/z 189. c The OsOSC12 committed triterpene pathway for biosynthesis of poaceatapetol esters
