PLA1 — Daucus carota subsp. sativus

Summary

DCAR_025024 (symbol DcPLA1, also known as DcSTS15 or PMEI) on carrot chromosome 7 encodes a protein containing a pectinesterase inhibitor domain and a Pla a 1-like domain, with annotated pectinesterase inhibitor activity and enzyme inhibitor activity. The gene is associated with pollen germination and pollen development, and its product localises to the pollen wall, endoplasmic reticulum, extracellular region and cytoplasm. Studies of related genes in other species link the family to fruit firmness, fruit size, chlorophyll content and cytoplasmic male sterility, though these associations are not yet established in carrot.
