ADC1 — Cicer arietinum

Summary

LOC101497888 (CaADC1) on chickpea chromosome 6 encodes an arginine decarboxylase, a pyridoxal phosphate-dependent enzyme. The gene is associated with polyamine and putrescine metabolism, arginine catabolism, and spermidine and nicotine biosynthesis. CaADC1 is linked to responses to abiotic stresses including cold, salinity, osmotic stress, wounding, and oxidative stress, as well as to signalling mediated by abscisic acid and jasmonic acid. Associations with immune response, signal transduction, and photosynthetic rate have also been noted. The encoded protein localises to the cytosol and nucleus and exhibits protein homodimerisation and binding activities. Studies of related genes in other species connect the family to drought tolerance, freezing tolerance, root architecture, seed development, flowering time, and bacterial disease resistance.
