CS4 — Daucus carota subsp. sativus

Summary

DcCS4 (DCAR_021483) on carrot chromosome 6 encodes a SAM-dependent methyltransferase with caffeine synthase, demethylphylloquinone methyltransferase, and S-adenosyl-L-methionine:benzoate carboxyl methyltransferase activities. The gene is associated with jasmonic acid and strigolactone biosynthesis, oxylipin and fatty acid anabolism, nicotinate metabolism, alkaloid metabolism, and responses to wounding and other organisms. It has been linked to regulation of secondary shoot formation, jasmonic acid signaling, and female flower formation. The encoded protein localizes to the cytoplasm and nucleus. Studies of related genes in other species connect the family to salicylic acid metabolism, systemic acquired resistance, methyl salicylate production, and defense responses, while research in tobacco links it to strigolactone biosynthesis and jasmonate metabolism, and work in potato associates it with wound healing.
