XTH7 — triticum aestivum

Summary

TRAESCS7A02G427300, symbol XTH7 and also known as TaXTH12, encodes a xyloglucan endotransglucosylase/hydrolase (XTH) belonging to the glycoside hydrolase family 16, with endoxyloglucan transferase and O-glucosyl hydrolase activities. This wheat gene on chromosome 7A is associated with drought and salt stress resistance, as observed for the XTH17 variant, and with drought tolerance and the SALTTL trait. It is linked to xyloglucan catabolism and metabolism, cell wall assembly, biogenesis, and organization, secondary cell wall biogenesis, and responses to abscisic acid and gibberellin. The encoded protein localizes to the apoplast and plant-type cell wall. Additional associations include fruit ripening, cellular homeostasis, transport, cell communication, lipid metabolism, and cell death. Studies of related genes in other species connect the XTH family to seed shattering.
