ADC — Solanum tuberosum

Summary

PGSC0003DMG400001662 (STADC) on potato chromosome 1 encodes an arginine decarboxylase (EC 4.1.1.19), a PLP-dependent enzyme. The gene is associated with arginine breakdown, putrescine, spermidine and polyamine anabolism, as well as shikimate, phenylpropanoid and secondary metabolism, sucrose anabolism and starch breakdown. It is linked to wound healing, response to nematodes, secretion, S phase, and localisation to the cytosol and nucleus. Associations with photosynthetic rate, root meristem size, iron deficiency tolerance, bacterial disease resistance, salt and cold tolerance, seed germination, leaf and root development, plant height, flowering time, and responses to abiotic stress, wounding, salicylic acid and jasmonic acid have been reported. Studies of related genes in other species link the ADC family to drought tolerance, freezing tolerance, polyamine content, root architecture and disease resistance.
