PMEI — Daucus carota subsp. sativus

Summary

DCAR_030437 (symbol PMEI, also known as DcPMEI2) on carrot chromosome 9 encodes a pectinesterase inhibitor domain-containing protein with pectinesterase inhibitor activity. The gene is associated with defense response and localises to the cytoplasm. Studies of the Arabidopsis relative link the PMEI family to drought tolerance, oxidative stress tolerance, and disease resistance. Sequence similarity connections further associate the family with fruit firmness, fruit size, cytoplasmic male sterility, and disease tolerance, though these relationships are not established for carrot.
