Vibrational spectroscopic image analysis of biological material using multivariate curve resolution-alternating least squares (MCR-ALS).
TL;DR: This protocol provides a user-friendly pipeline and graphical user interface for data pre-processing and unmixing of pixel spectra into their contributing pure components by multivariate curve resolution–alternating least squares (MCR-ALS) analysis.

TL;DR: It is shown that lignification occurs after programmed cell death in xylem tracheary elements (TEs) of Zinnia elegans xylogenic cell cultures and that living, parenchymaticxylem cells surrounding the TEs synthesize and transport lignin monomers and reactive oxygen species to the cell walls of the dead TEs, thus enabling the postmortem lignified TEs.
Journal ArticleDOI
MYB103 is required for FERULATE‐5‐HYDROXYLASE expression and syringyl lignin biosynthesis in Arabidopsis stems
David Öhman,Brecht Demedts,Brecht Demedts,Manoj Kumar,Lorenz Gerber,András Gorzsás,Geert Goeminne,Geert Goeminne,Mattias Hedenström,Brian E. Ellis,Wout Boerjan,Wout Boerjan,Björn Sundberg +12 more
TL;DR: It is demonstrated that F5H expression and hence biosynthesis of S lignin are dependent on MyB103, a direct transcriptional target of the transcription factor SECONDARY WALL ASSOCIATED NAC DOMAIN PROTEIN 1 (SND1), and 35S-driven dominant repression or over-expression of MYB103 modifies secondary wall thickness.
Journal ArticleDOI
Cell-specific chemotyping and multivariate imaging by combined FT-IR microspectroscopy and orthogonal projections to latent structures (OPLS) analysis reveals the chemical landscape of secondary xylem.
TL;DR: Fourier transform infrared (FT-IR) spectroscopy combined with microscopy enables acquiring chemical information from native plant cell walls with high spatial resolution as mentioned in this paper, using a 64 x 64 fo...
Journal ArticleDOI
Speciation in peroxovanadate systems
TL;DR: In this paper, a detailed and thorough potentiometric and 51V-NMR spectroscopic investigation of H+ −H2VO4−−−H2O2-Ligand systems has been performed at 25 °C in 0.15 M Na(Cl) ionic medium.
