ADC — Cucumis melo

Summary

MELO3C023359.2, designated CmADC on melon chromosome 12, encodes an arginine decarboxylase (EC 4.1.1.19) with a PLP-binding barrel domain and arginine decarboxylase activity. CmADC is associated with putrescine, spermidine and polyamine anabolism, as well as arginine breakdown and alkaloid metabolism. The gene is linked to responses to jasmonic acid, abscisic acid, cold, wounding, oxidative stress, osmotic stress and salinity. It localises to the cytosol and nucleus. Associations with photosynthetic rate, root meristem size, seed development, germination, leaf development, plant height, iron deficiency tolerance, bacterial disease resistance, and cold tolerance have been reported. Studies of related genes in other species connect the family to drought tolerance, polyamine content, root architecture and freezing tolerance.
