ARABINAN DEFICIENT 1 Is a Putative Arabinosyltransferase Involved in Biosynthesis of Pectic Arabinan in Arabidopsis1[W]
TLDR
Analysis of mutant lines with T-DNA insertion in the ARABINAN DEFICIENT 1 gene suggested that ARAD1 is an arabinan α-1,5-arabinosyltransferase, a putative glycosyl transferase of type 2 membrane protein with a signal anchor in Arabidopsis.
Modulation of the Degree and Pattern of Methyl-esterification of Pectic Homogalacturonan in Plant Cell Walls
TLDR
It is demonstrated that, in addition to blockwise de-esterification, HG with a non-blockwise distribution of methyl esters is also an abundant feature of HG in primary plant cell walls, implications for understanding of both the action of pectin methyl esterases on matrix properties and mechanisms of intercellular adhesion and its loss in plants.
Loss-of-Function Mutation of REDUCED WALL ACETYLATION2 in Arabidopsis Leads to Reduced Cell Wall Acetylation and Increased Resistance to Botrytis cinerea1[W][OA]
TLDR
Four Arabidopsis homologs of the protein Cas1p known to be involved in polysaccharide O-acetylation in Cryptococcus neoformans showed increased tolerance toward the necrotrophic fungal pathogen Botrytis cinerea, and there were no obvious morphological or growth differences observed between the wild type and rwa2 mutants.
Novel cell wall architecture of isoxaben-habituated Arabidopsis suspension-cultured cells: global transcript profiling and cellular analysis.
TLDR
Near whole-genome transcript profiling implicated novel genes in cell wall assembly and extended the understanding of the activity of known cell wall-related genes including glycosyltransferases involved in cellulose and pectin biosynthesis, among the cellulose synthase superfamily.
The Availability and Nutritional Adequacy of Gluten-Free Bread and Pasta
TLDR
It is recommended that fortification legislation is extended to include all GF products, in addition to increased regulation of the nutritional content of GF foods, to reduce the risk of micronutrient deficiency in coeliac sufferers.
Altered middle lamella homogalacturonan and disrupted deposition of (1-->5)-alpha-L-arabinan in the pericarp of Cnr, a ripening mutant of tomato.
TLDR
It is demonstrated that maturation processes involving middle lamella HG are altered in Cnr fruit, resulting in the absence or a low level of HG-/calcium-based cell adhesion, and that the deposition of (1-->5)-alpha-L-arabinan is disrupted in CNR pericarp CW and that this disruption occurs prior to fruit ripening.
Influence of combined biotic and abiotic stress on nutritional quality parameters in tomato (Solanum lycopersicum).
TLDR
The combined effect of water stress and infection with plant-parasitic nematodes on the nutritional quality of tomato was investigated and the levels of phenolic compounds, carotenoids, and sugars in fruits were analyzed.
