GASA1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G154860, also known as TtGASA1, encodes a GASA-domain family protein on durum wheat chromosome 1B. The product is annotated with microtubule and protein binding activities. This gene is associated with responses to multiple hormones, including brassinosteroid, gibberellin, auxin, and abscisic acid, as well as with defense response, signal transduction, leaf vascular tissue pattern formation, polar cell growth, and osmotic response. It has been linked to traits such as brassinosteroid sensitivity, drought tolerance, and reduced root length, and to phenotypes including gibberellin response, apical hook formation, and abnormal leaf venation with reduced vein number. The protein localizes to the plant-type cell wall, extracellular region, mitochondria, cytosol, plasmalemma, and cytoplasm. Studies of related genes in other species connect the GASA family to seed germination, seed maturation, seed dormancy, and gibberellic acid sensitivity.
