SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_2G024720) on sugar beet chromosome 2 encodes a protein with beta-glucanase and XTH domains, and has endoxyloglucan transferase activity, O-glucosyl hydrolase activity, and polysaccharide binding. The gene is associated with xyloglucan catabolism and metabolism, cell wall assembly, biogenesis, organization, and secondary cell wall biogenesis, as well as cellular response to gibberellin stimulus, response to abscisic acid, jasmonic acid anabolism, fruit ripening, and signal transduction. Its product localizes to the apoplast, plant-type cell wall, and cytoplasm. BvSEN4 has been linked to sugar content. Studies of related genes in other species, such as brassinosteroid-regulated protein BRU1 and various XTHs, link the family to cell wall modification and hormone-responsive growth processes.
