Identification of endogenous MeCLA in Arabidopsis. Endogenous SL-LIKE1 was identified as MeCLA using LC-MS/MS (QTOF). Ion traces from the LC-MS/MS analysis (Left) and product ion spectra (Right) derived from respective precursor ions of [10-2H1]MeCLA (internal standard) and endogenous SL-LIKE1 extracted from roots of Arabidopsis atd14 mutant and those of unlabeled authentic MeCLA are shown.
