DEC — Arabidopsis thaliana

Summary

AT5G49720 (DEC/KOR/KOR1) encodes an endoglucanase (EC 3.2.1.4) belonging to the glycosyl hydrolase 9 family, with cellulase activity and cellulose synthase activity. In Arabidopsis, this gene is associated with cellulose breakdown, primary and secondary cell wall biogenesis, pectin metabolism, cell adhesion, leaf abscission, dehiscence, and secondary growth. It localizes to the cell plate, Golgi, trans-Golgi network, early endosome, plasmodesmata, and the cellulose synthase complex. The gene has been linked to numerous traits including stem length and elongation, seed weight and protein content, biomass yield, lignin content, phosphate content, glucose content, oleic acid content, turgor pressure, drought tolerance, osmotic stress tolerance, herbicide sensitivity, and responses to powdery mildew and insect damage. Phenotypic associations include dwarfism, collapsed xylem, reduced fertility, altered cell shape, and defective secondary wall formation.
