ADC1 — Medicago truncatula

Summary

MTR_4G072020 (MtADC1) encodes an arginine decarboxylase, a pyridoxal-phosphate-dependent enzyme. The gene is associated with polyamine and putrescine metabolism, arginine breakdown, the urea cycle, proline metabolism, nitrogen fixation, and responses to salt, oxidative stress, jasmonic acid, and osmotic stress. It is linked to photosynthetic rate, stomatal resistance, root meristem size, seed germination, plant height, leaf development, and tolerance to cold, salt, iron deficiency, atrazine, and bacterial disease. The encoded protein localises to the cytosol and nucleus. Studies of related genes in other species connect the family to putrescine accumulation, polyamine content, seed development, root architecture, drought tolerance, freezing tolerance, and shoot meristem formation.
