Catalytic subunit stoichiometry within the cellulose synthase complex.
Cellulose synthesis is driven by large plasma membrane-inserted protein complexes, which in plants have 6-fold symmetry. In Arabidopsis (Arabidopsis thaliana), functional cellulose synthesis complexes (CSCs) are composed of at least three different cellulose synthase catalytic subunits (CESAs), but the actual ratio of the CESA isoforms within the CSCs remains unresolved. In this work, the stoic...
متن کاملThree distinct rice cellulose synthase catalytic subunit genes required for cellulose synthesis in the secondary wall.
Several brittle culm mutations of rice (Oryza sativa) causing fragility of plant tissues have been identified genetically but not characterized at a molecular level. We show here that the genes responsible for three distinct brittle mutations of rice, induced by the insertion of the endogenous retrotransposon Tos17, correspond to CesA (cellulose synthase catalytic subunit) genes, OsCesA4, OsCes...
متن کاملThe Arabidopsis cellulose synthase complex: a proposed hexamer of CESA trimers in an equimolar stoichiometry.
Cellulose is the most abundant renewable polymer on Earth and a major component of the plant cell wall. In vascular plants, cellulose synthesis is catalyzed by a large, plasma membrane-localized cellulose synthase complex (CSC), visualized as a hexameric rosette structure. Three unique cellulose synthase (CESA) isoforms are required for CSC assembly and function. However, elucidation of either ...
متن کاملUpdate on Cellulose Synthase Trafficking Trafficking of the Plant Cellulose Synthase Complex
Cellulose is the most abundant component of plant cell walls and its importance is well documented. In the primary cell wall it forms part of the load-bearing network that both controls and maintains cell shape, while allowing regulated cell expansion that is essential during growth. Cellulose is also the major component of secondary cell walls where it is required for mechanical strength for t...
