CS4 — Daucus carota subsp. sativus

Summary

DcCS4 (DCAR_025963) on carrot chromosome 7 encodes a SAM-dependent methyltransferase with demethylphylloquinone methyltransferase, benzoate carboxyl methyltransferase, and methyl jasmonate methylesterase activities. The gene is associated with jasmonic acid, oxylipin, strigolactone, and nicotinate metabolism, as well as responses to wounding, ethylene, and other organisms. It has been linked to female flower formation, parasitoid attraction, and regulation of secondary shoot formation. The protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to defense responses, herbivore defense, disease resistance, volatile organic compound emission, and traits including jasmonic acid content, chlorophyll content, drought tolerance, and shoot branching.
