SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_8G190170) on sugar beet chromosome 8 encodes a xyloglucan endotransglucosylase/hydrolase (XTH) family protein with xyloglucan-specific endo-beta-1,4-glucanase and endoxyloglucan transferase activities. The gene is associated with cell wall loosening, assembly, and organization, as well as xyloglucan catabolism and metabolism. It is linked to responses to gibberellin, auxin, and brassinosteroid stimuli, and to primary root development, leaf vascular tissue pattern formation, and fruit ripening. The protein localizes to the apoplast, plant-type cell wall, Golgi complex, and secretory vesicle. Associations with agronomic traits include sugar content, seed growth and development, aluminum response, brassinosteroid sensitivity, and phenotypes such as lateral root development, salt tolerance, leaf senescence, and freezing tolerance.
