Fast phenotyping of LFS-silenced (tearless) onions by desorption electrospray ionization mass spectrometry (DESI-MS).

Journal of agricultural and food chemistry - 20 Feb 2013

Abstract excerpt

Fast MS techniques have been applied to the analysis of sulfur volatiles in Allium species and varieties to distinguish phenotypes. Headspace sampling by proton transfer reaction (PTR) MS and surface sampling by desorption electrospray ionization (DESI) MS were used to distinguish lachrymatory factor synthase (LFS)-silenced (tearless; LFS-) onions from normal, LFS-active (tear-inducing; LFS+), onions. PTR-MS...
