Polysaccharides and Plant Cell Walls

This study identifies six prolyl-4 hydroxylases in mosses and characterizes their substrate specificity, structural features, and functional roles in proline hydroxylation and O-glycosylation.

This study identifies galacturonic acid and its oxidized form, galactaric acid, as key monomers regulating cell adhesion through extensin crosslinking in plant cell walls.

This study identifies glucosylceramides as regulators of cellulose deposition and cellulose synthase complex motility in Arabidopsis by showing their impact on sphingolipid composition and CSC activity.

This study examines how changes in prolyl 4 hydroxylase (P4H3) activity affect arabinogalactan protein (AGP) structure and distribution during tomato fruit ripening.

This study identifies SUH1 as a genetic suppressor of CTL1 mutations in Arabidopsis, revealing their antagonistic roles in cell wall assembly through cellulose regulation.

The paper shows that RHM1 forms condensates called rhamnosomes, which are essential for UDP-rhamnose synthesis and plant organ development.

This study shows that PHOSPHATE-INDUCED 1 and its paralogs regulate cellulose biosynthesis in Arabidopsis by modulating CSC activity in response to developmental and environmental cues.

The paper investigates the role of CSI1 in sepal morphogenesis, finding that it ensures spatial consistency of cell growth direction despite altered cellulose microfibril alignment in mutants.

This study identifies BK2L3, a COBRA family gene, as essential for cell wall formation and carbohydrate partitioning in maize, linking cellulose deposition to phloem function and plant growth.

The paper solves the crystal structures of Pc1,3Gal43A, an exo-β-1,3-galactanase from Phanerochaete chrysosporium, revealing its mechanism for bypassing side chains in arabinogalactan proteins.

The paper uses a yeast-based split ubiquitin system to screen for protein-protein interactions of a Golgi-localized type II membrane protein, identifying known and novel interaction partners.

This study shows XTH4 and XTH9 regulate xylem cell expansion and secondary wall formation in Arabidopsis through cell wall integrity signaling.

The paper investigates cell expansion and proliferation in Fucus embryos, showing correlations between cell wall mechanics, alginate biochemistry, and growth patterns, with transcriptomic data supporting gene expression changes related to wall stiffness.
