SEN4 — Brassica oleracea var. botrytis

Summary

BoSEN4 (SEN4, also known as BoMERI5B or BoXTH24) on chromosome 7 of cauliflower encodes a protein belonging to the glycoside hydrolase family 16, with endoxyloglucan transferase and O-glucosyl hydrolase activities. The gene is associated with xyloglucan catabolism, cell wall loosening, assembly, and biogenesis, as well as responses to gibberellin, brassinosteroid, and abscisic acid. It has been linked to leaf senescence, meristem development, cell elongation, and hypocotyl cell elongation. The encoded protein localises to the plant cell wall, apoplast, Golgi complex, secretory vesicles, and plasma membrane. Studies of related genes in other species connect the family to leaf size, leaf shape, chlorophyll content, phyllotaxy, and turgor pressure.
