STR — Medicago truncatula

Summary

MTR_7G091380 (symbol STR, also known as MtABCA1) in barrel medic (Medicago truncatula) on chromosome 7 encodes an ABC transporter of the ABCA subfamily, with ATP hydrolase activity and annotated functions including thiosulphate and sulfate ABC transporter activity, amino acid permease activity, and ATP-coupled transmembrane transporter activity. The gene is associated with a wide range of biological processes, including arbuscular mycorrhizae formation, response to symbiotic fungi, suberin biosynthetic process, cellular salinity and osmotic responses, potassium and sodium ion homeostasis, response to salt, salicylate, and gibberellin, cellular response to hypoxia, exocytosis, secretion, lipogenesis, regulation of secondary shoot formation, and vision. Its product localises to the periarbuscular membrane, Casparian strip, suberin network, plant-type vacuole, mitochondria, and plasmalemma. Studies of related genes in other species link the family to root morphology traits and arsenic concentration.
