SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_1G009300) on sugar beet chromosome 1 encodes a xyloglucan endotransglucosylase/hydrolase (XTH) family protein with endoxyloglucan transferase and O-glucosyl hydrolase activities. The gene is associated with xyloglucan catabolism and metabolism, cell wall assembly, biogenesis, organization, and secondary cell wall biogenesis. It is linked to responses to abscisic acid and gibberellin stimulus, jasmonic acid anabolism, signal transduction, and fruit ripening. The encoded protein localizes to the apoplast, plant-type cell wall, and cytoplasm. BvSEN4 is also associated with sugar content. Studies of related genes in other species, such as brassinosteroid-regulated protein BRU1 and XTH1-8, connect this family to cell wall remodeling and hormone-responsive growth processes.
