MATE — Daucus carota subsp. sativus

Summary

DCAR_002071 (DcMATE, also known as DcDTX42) on carrot chromosome 1 encodes a MATE family protein with a DinF-like domain and antiporter activity, functioning as a citrate and xenobiotic transmembrane transporter. In carrots, this gene is associated with citrate transport, anthocyanin biosynthesis, and response to aluminum and heavy metal stress, with the protein localised to the plasma membrane and root hairs. DcMATE is associated with anthocyanin content. Related genes in other species are linked to aluminum tolerance, drought tolerance, root morphology traits, and resistance to fusarium head blight and fusarium wilt, though these associations are not yet established in carrot.
