MLO — Medicago truncatula

Summary

MTR_6G033330, designated MtMLO, encodes a calmodulin-binding protein localised to the plasmodesma, Golgi complex, extracellular space, membrane, mitochondria and plasmalemma in barrel medic (Medicago truncatula) chromosome 6. The gene is associated with defence responses to both fungi and bacteria, as well as downregulation of defence response. MtMLO has been connected to Botrytis cinerea resistance, leaf senescence, systemic acquired resistance and callose deposition. Studies of related genes in other species link the family to powdery mildew resistance, disease resistance and susceptibility, non-host resistance to Magnaporthe oryzae, and ozone tolerance. The family has also been associated with wheat powdery mildew disease response, stomatal resistance, seed maturation, seed dormancy, leaf senescence, disease tolerance, salt tolerance and root morphology traits.
