SEN4 — Asparagus officinalis

Summary

A4U43_C06F16660 (SEN4) on asparagus chromosome 6 encodes a protein with beta-glucanase and XTH domains, belonging to the GH16 family, and has endoxyloglucan transferase activity and xyloglucan-specific endo-beta-1,4-glucanase activity. The gene is associated with xyloglucan catabolism, cell wall loosening, assembly, and organization, as well as responses to gibberellin, auxin, brassinosteroid, salt, and far-red light. It is linked to primary root development, leaf vascular tissue pattern formation, secondary cell wall biogenesis, and lignin anabolism. The product localizes to the apoplast, plant-type cell wall, Golgi, and secretory vesicle. Associations include chlorophyll content, seed growth, aluminum response, brassinosteroid sensitivity, lateral root development, salt tolerance, leaf senescence, freezing tolerance, and shade avoidance. Studies of related genes in other species connect the family to root elongation, vascular development, and aluminum tolerance.
