MLO — Pisum sativum

Summary

PsMLO (PSAT1G099840) on garden pea chromosome 1LG6 encodes a calmodulin-binding protein with additional protein-binding capacity. The gene is associated with defense responses, including downregulation of defense response, response to fungi, and defense responses to both bacteria and fungi. It has been linked to Botrytis cinerea resistance, leaf senescence, systemic acquired resistance, and callose deposition. The protein localizes to the plasmodesma, Golgi complex, extracellular space, membrane, mitochondria, and plasmalemma. Related genes in other species are associated with powdery mildew resistance, disease resistance, ozone tolerance, and non-host resistance to Magnaporthe oryzae, and sequence similarity links extend to traits such as seed maturation, seed dormancy, leaf senescence, and disease tolerance.
