YUC2 — Medicago truncatula

Summary

MtYUC2 (MTR_6G086870) on chromosome 6 of barrel medic encodes a flavin monooxygenase-like protein with indole-3-pyruvate monooxygenase activity. The gene is associated with auxin anabolism, auxin content, and auxin homeostasis, as well as organogenesis, regulation of leaf and root development, nodulation, nitrogen fixation, anther dehiscence, and response to ethylene. It has been linked to adventitious root initiation, de novo root organogenesis, vascular regeneration, floral organ formation, pollen development and maturation, style development, cell specification, shade avoidance, and chloroplast RNA editing. The encoded protein localises to the endoplasmic reticulum, mitochondria, and nucleus. Studies of related genes in other species connect the family to leaf colour, leaf size, chlorophyll content, photochemical quenching, and vascular tissue morphology.
