CESA1 Antibody

1. AtCesA6-null mutants showed a reduced cell elongation of young seedlings with little impact on cell division, which consequently affected cell wall integrity and biomass yield of mature plants. In comparison, rsw1 seedlings exhibited a strong defect in both cell elongation and division at restrictive temperature, whereas the IRX3 mutant showed normal seedling growth. PMID: 29514326
2. Our data support a model in which distinct spatiotemporal features of active CSCs (cellulose synthase (CESA) complex))during PCW and SCW synthesis contribute to the formation of cellulose with distinct structure and organization in PCWs and SCWs of Arabidopsis thaliana PMID: 27647923
3. microscopy showed that two altered versions of Atcesa1 could rescue cell wall phenotypes observed in the mutant background line. Overall, the data show that the FxVTxK motif is functionally important in two phylogenetically distant plant CESAs. PMID: 26646446
4. A low resolution structure of the catalytic domain of CESA1 determined by small-angle scattering techniques provides the first experimental evidence for the self-assembly of CESA1 into a stable trimer. PMID: 26556795
5. The stoichiometry of the cellulose synthase catalytic subunits (CESAs) in the primary cell wall CSC was determined and CESA1, CESA3, and CESA6 are present in a 1:1:1 molecular ratio. PMID: 25352273
6. computational findings on transmembrane helices (TMHs) 5 and 6 in three CESAs of Arabidopsis thaliana (AtCESA1, 3, and 6), the Atcesa3(ixr1-2) mutant, and a novel missense mutation in AtCESA1, are reported. PMID: 25262226
7. Relatively high sequence conservation between plant CESAs allowed mapping of known mutations and two previously undescribed mutations that perturb cellulose synthesis in Arabidopsis thaliana to their analogous positions in the modeled structure. PMID: 23592721
8. CESA1(A903V) and CESA3(T942I) have modified microfibril structure in terms of crystallinity and suggest that in plants, as in bacteria, crystallization biophysically limits polymerization. PMID: 22375033
9. Data suggest that phosphorylation of CESA1 affects polar interactions with microtubules that may regulate the length or quantity of a subset of cellulose microfibrils and that this, in turn, alters microfibril structure in the primary cell wall. PMID: 20855602
10. The effects of CESA1 and CESA3 mutations and chimeric proteins on the temperature sensitivity of A. thaliana is reported. PMID: 16891551
11. CESA 1, 3, and 6 form a complex which is important for cellulose synthesis. PMID: 18495638
