SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_5G110610) on sugar beet chromosome 5 encodes a xyloglucan endotransglucosylase/hydrolase (XTH) family protein with endoxyloglucan transferase and xyloglucan-specific endo-beta-1,4-glucanase activities. The product is associated with xyloglucan catabolism, cell wall loosening, assembly and organization, and localizes to the apoplast, plant-type cell wall, Golgi and secretory vesicles. It has been linked to responses to gibberellin, auxin, brassinosteroid, far-red light, and jasmonic acid anabolism, as well as primary root development, leaf vascular tissue pattern formation, and secondary cell wall biogenesis. Associations with sugar content, seed growth, brassinosteroid sensitivity, aluminum response, salt tolerance, freezing tolerance, leaf senescence, and shade avoidance have been noted. Related genes in other species are linked to root elongation, vascular development, cell wall rigidity, and aluminum tolerance.
