STR — Medicago truncatula

Summary

MTR_4G089130, also known as STR, encodes an ABC transporter with ATP hydrolase activity and ATP-binding capability, belonging to the ABCG transporter family. In barrel medic (Medicago truncatula) on chromosome 4, this gene is associated with suberin biosynthetic processes and localises to the suberin network, Casparian strip, periarbuscular membrane, and plasma membrane. It is linked to cellular responses to salt, osmotic stress, hypoxia, and salicylate, as well as potassium and sodium ion homeostasis, exocytosis, secretion, and green leaf volatile biosynthesis. The gene has also been connected to arbuscular mycorrhizae formation and response to symbiotic fungi, along with regulation of secondary shoot formation and lipogenesis. Related genes in other species link the family to similar transport and stress-response functions.
