PLD1 — Zea mays

Summary

ZM00001EB122860, also known as PLD1 and ZmMEE54 on maize chromosome 3, encodes a phospholipase D enzyme with phospholipase D activity, along with associated functions including lead ion binding, GTPase inhibitor activity, and fatty-acyl-CoA binding. The gene is associated with phosphatidylcholine breakdown, phosphatidic acid metabolism, and triglyceride storage, as well as pollen adhesion and tube development. It has been associated with numerous agronomically relevant traits including seed weight and oil content, stay green trait, net photosynthetic rate, nitrate uptake and sensitivity, and responses to biotic stress, UV light, and heavy metals. The encoded protein localizes to the plasma membrane region, clathrin-coated vesicles, and the microtubule cytoskeleton. Studies of related genes in other species link the family to drought tolerance, salt tolerance, seed quality, and stomatal closure.
