WtsE induces CouTyr accumulation in sweet maize ‘Seneca Horizon’ seedlings. A, Liquid chromatography-tandem mass spectrometry (LC-MS/MS) chromatograms showing overlaid total ion counts (TIC) of precursor mass ion scans (positive ion mode) of extracts of cv Seneca Horizon seedlings from 20 h after infiltration with wild-type Pnss (DC283; black trace) and the wtsE null mutant (DM5101; gray trace). WtsE-dependent accumulation of CouTyr is apparent at an acquisition time of approximately 7.1 min (arrow). B and C, Extracted ion counts (EIC) of putative CouTyr species (m/z = 284) in extracts from plants infiltrated with DC283 (B) or DM5101 (C) as in A. D, Quantification of CouTyr in extracts of plants treated as in A. Shown are combined data and sd from six biological replicates (n = 12). FW, Fresh weight.
