CEV1 — Arabidopsis thaliana

Summary

AT5G05170 (CEV1, AtCESA3) encodes a cellulose synthase with protein-cysteine S-palmitoyltransferase activity, belonging to the cellulose synthase and zinc finger RING domain families. It is a core component of the cellulose synthase complex and localizes to cortical microtubules, the Golgi membrane, and the cell plate. The gene is associated with primary cell wall biogenesis, cellulose and glucan anabolism, regulation of microtubule dynamics, and positive regulation of abscisic acid anabolism. Phenotypically, CEV1 is linked to plant growth, cellulose content, root cell shape and division, jasmonate signaling, and herbicide resistance. It has also been connected to seed mucilage attachment and structure, seed weight, biomass yield, stem elongation, water use efficiency, lignin content, and responses to insect damage and powdery mildew. Related genes in other species link the family to cellulose synthesis.
