SEN4 — Beta vulgaris subsp. vulgaris

Summary

BvSEN4 (BVRB_2G040540) on sugar beet chromosome 2 encodes a protein with xyloglucan-specific endo-beta-1,4-glucanase activity, endoxyloglucan transferase activity, and O-glucosyl hydrolase activity, belonging to the GH16 beta-glucanase/XTH domain family. The product is associated with xyloglucan catabolism and metabolism, cell wall loosening, assembly, organization and biogenesis, including secondary cell wall biogenesis, and localizes to the apoplast, plant-type cell wall, Golgi and secretory vesicles. It is linked to responses to gibberellin, auxin, brassinosteroid and far-red light, as well as jasmonic acid biosynthesis, primary root development, leaf vascular tissue patterning, fruit ripening, and traits including sugar content, seed growth and development, brassinosteroid sensitivity, and aluminum response. Studies of related XTH family members in other species connect the family to root elongation, cell expansion, freezing tolerance, aluminum resistance, and shade avoidance.
