SAR1 — Triticum turgidum subsp. durum

Summary

TRITD5AV1G222440, designated SAR1 (also known as VAMP7B and VAMP721–VAMP726) on durum wheat chromosome 5A, encodes a protein containing a V-SNARE coiled-coil domain and a longin domain, and is annotated with SNARE, protein membrane adaptor, and voltage-sensitive potassium channel activities. The gene is associated with membrane fusion, cell plate formation, secretion, protein localization to the plasma membrane, and plasmodesma-mediated transport. It is linked to defense responses including callose deposition, salicylic acid signaling, and responses to powdery mildew, nematodes, and insects. Associations also include drought tolerance, cadmium concentration, abscisic acid sensitivity, stomatal closure, root and leaf morphology, flowering time, anthocyanin content, and cell growth traits. Studies of related genes in other species connect the family to potassium channel activity, pathogen immunity, and pollen tube growth.
