ST1 — Medicago truncatula

Summary

MTR_2G067080 (MtST1) in barrel medic (Medicago truncatula) on chromosome 2 encodes a protein with mercaptopyruvate sulfurtransferase and thiosulfate-cyanide sulfurtransferase activities, belonging to the rhodanese-like domain family. The gene is associated with strigolactone anabolism, vasculature development, nodulation, lateral root and root development, organogenesis, embryo and seed development, exocytosis, secretion, defense response, and response to thirst. It is linked to traits including leaf number, root length, plant height, and drought tolerance, as well as phenotypes such as persulfide formation, embryo development, seed development, and senescence. The encoded protein localizes to mitochondria, cytosol, and cytoplasm. Related genes in other species link the family to rhodanese activity and iron-sulfur enzyme activity.
