An extended set of monoclonal antibodies to pectic homogalacturonan.
TLDR
Three novel rat monoclonal antibodies, designated LM18, LM19 and LM20, were isolated from screens for binding to Arabidopsis thaliana seed coat mucilage and indicated their recognition of pectic homogalacturonan epitopes.
Pectic homogalacturonan masks abundant sets of xyloglucan epitopes in plant cell walls
TLDR
Observations support ideas that xyloglucan is associated with pectin in plant cell walls and indicate that documented patterns of cell wall epitopes in relation to cell development and cell differentiation may need to be re-considered in connection to the potential masking of cellwall epitopes by other cell wall components.
Structural variability of arabinoxylans from wheat flour. Comparison of water-extractable and xylanase-extractable arabinoxylans
The structural variations in water-extractable arabinoxylans (WE-AX) and water-unextractable AX (WU-AX) in a collection of flours from twenty wheat (Triticum aestivum) cultivars was compared using
Cell wall microstructure analysis implicates hemicellulose polysaccharides in cell adhesion in tomato fruit pericarp parenchyma.
TLDR
Observations indicate that hemicellulose polymers are present in architectural contexts reflecting cell adhesion and that several cell wall polysaccharide classes are likely to contribute to cellAdhesion/cell separation in tomato fruit pericarp parenchyma.
Classification of wheat varieties based on structural features of arabinoxylans as revealed by endoxylanase treatment of flour and grain.
TLDR
The method combining endoxylanase treatment of wheat grain and the analysis of degradation products, e.g., enzymatic fingerprinting, can be applied to collections of wheat cultivars, and possibly other cereals in order to establish quantitative trait loci related to the biosynthesis of AX.
Genomic history of the origin and domestication of common bean unveils its closest sister species
TLDR
An unpredicted speciation event in the tropical Andes that gave rise to a sibling species, formerly considered the “wild ancestor” of P. vulgaris, is uncovered and haplotypes strongly associated with genes underlying the emergence of domestication traits are identified.
Assessing temporal flux of plant hormones in stored processing potatoes using high definition accurate mass spectrometry
TLDR
It is reported for the first time that abscisic acid glucose ester seems to accumulate in the skin of potato tubers throughout storage time.
Structural characterization of underivatized arabino-xylo-oligosaccharides by negative-ion electrospray mass spectrometry.
TLDR
The CID spectra of linear xylo-oligosaccharides and of nine isomeric mono- and disubstituted arabino- xylosyl residues established that structures differing in their substitution pattern can be differentiated by this approach.
Developing Pericarp of Maize: A Model to Study Arabinoxylan Synthesis and Feruloylation
TLDR
The study shows that the pericarp of the maize B73 line contains the highest level of ferulic acid reported in plant tissue, and supports the hypothesis that the feruloylated moiety of xylans originated fromFeruloylCoA and is transferred by a member of the BAHD acyltransferase family.
Homoisoflavonoids Are Potent Glucose Transporter 2 (GLUT2) Inhibitors: A Potential Mechanism for the Glucose-Lowering Properties of Polygonatum odoratum.
TLDR
A new mechanism of the glucose-lowering action of P. odoratum suggests that SAP homoisoflavonoids and their combination with flavonoid monoglucosides show promise as naturally functional ingredients for inclusion in foods and drinks designed to control postprandial glucose levels.
