SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_013490) on sugar beet chromosome 0470.scaffold01016 encodes a xyloglucan endotransglucosylase/hydrolase (XTH) with endoxyloglucan transferase and xyloglucan-specific endo-beta-1,4-glucanase activities. The product belongs to the GH16 family and is associated with xyloglucan catabolism, cell wall loosening, assembly and organization, as well as responses to gibberellin, auxin and brassinosteroid stimuli. It is linked to primary root development, leaf vascular tissue pattern formation, fruit ripening, and secondary cell wall biogenesis. The protein localizes to the apoplast, plant-type cell wall, Golgi complex and secretory vesicles. Associations include sugar content, seed growth and development, brassinosteroid sensitivity, aluminum response, lateral root development, salt tolerance, freezing tolerance, leaf senescence, shade avoidance, and petiole elongation. Studies of related genes in other species link the XTH family to root elongation, vascular development, aluminum tolerance, and freezing stress resistance.
