Research Abstract

Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) was applied to detect monolignol glucosides in differentiating xylems of several Japanese softwoods. MALI-IMS combined with osmium tetroxide vapor treatment enabled us to distinguish distribution of sucrose and coniferin with the same molecular weight. MALDI-IMS using transverse sections of normal wood in Japanese cypress (Chamaecyparis obtusa) showed that coniferin was mainly distributed in tracheids during secondary wall formation.
