MLO — Cucumis sativus

Summary

CSA_6G355430, designated MLO (also known as CsMLO10 and CsMLO5) in cucumber (Cucumis sativus) on chromosome 6, encodes a member of the MLO protein family. The product exhibits calmodulin binding and protein binding activities and is localized to the membrane, endomembrane system, plasmalemma, cytoplasm, nucleus, and mitochondria. This gene is associated with cell wall thickening, pollen tube reception and guidance, protein localization to the plasma membrane, immune and defense responses, ABA and calcium signaling, and signal transduction. It has been connected to wheat powdery mildew disease response. Studies of related MLO family members in other species link the family to powdery mildew resistance, defective pollen tube guidance, reduced fertility, and traits including shoot dry weight and drought tolerance.
