LAC2 — Daucus carota subsp. sativus

Summary

DCAR_015633 (DcLAC2) on carrot chromosome 4 encodes a laccase, a copper-containing p-diphenol:oxygen oxidoreductase (EC 1.10.3.2) with copper-binding and redox activity. The protein belongs to the multicopper oxidase family and is localised to the apoplast. DcLAC2 is associated with lignin breakdown and seed growth, and has been linked to abiotic stress tolerance and the abiotic plant stress response trait. Studies of related genes in other species further connect the family to oxidative processes, though these associations are not yet established in carrot.
