TL;DR: Biochemical methods successfully led to the recent identification of a pectin biosynthetic galacturonosyltransferase (GAUT1), and recent functional genomics and mutant studies have allowed the identification of several biosynthetics enzymes involved in making different parts of pectIn several other cases, enzymes have been identified as involved inMaking pect in but because of ambiguity in the cell wall compositions of mutants and lack of direct biochemical evidence their specific activities are more uncertain.

TL;DR: Recent progress in the identification and characterization of genes encoding proteins involved in the biosynthesis of Arabidopsis cell-wall polysaccharides and arabinogalactan proteins is covered.

TL;DR: Results suggest that RGXT1 and RGXT2 encode Golgi-localized (1,3)-α-d-xylosyltransferases involved in the biosynthesis of pectic rhamnogalacturonan-II, a complex polysaccharide essential to vascular plants.

TL;DR: Results confirm that the XGD1 protein is a XGA xylosyltransferase, shown by expression of a fluorescent fusion protein in N. benthamiana to be localized in the Golgi vesicles as expected for a glycosyl transferase involved in pectin biosynthesis.

TL;DR: Data indicate that resistance is dependent on a fast, initial recognition of the pathogen, probably due to beta-1,3-glucan in the fungal cell walls, and this results in the accumulation of beta-2,3, glucanase and structural defence responses, which may directly inhibit the Pathogen and protect the host against fungal enzymes and toxins.
