TAR2 — Pisum sativum

Summary

PSAT0S2597G0240, designated PsTAR2, encodes a protein with tryptophan aminotransferase activity, alliin lyase activity, pyridoxal phosphate binding, and chloride ion binding, belonging to the alliinase and pyridoxal-dependent transferase families. In garden pea, this gene is associated with auxin biosynthesis, IAA biosynthetic process, and responses to ethylene and nitrogen levels. It is linked to numerous developmental processes including cotyledon, embryo, seed, flower, pistil, and shoot development, as well as primary root development, positive gravitropism, phloem or xylem histogenesis, and cotyledon vascular tissue pattern formation. The gene is also connected to defence response to bacteria, vacuole formation, nitrogen use efficiency, lateral root growth, meristem patterning, and cell wall function. Localisation evidence places the product at the vacuole and ER membrane. Studies of related genes in other species link this gene family to auxin biosynthesis and root branching.
