MSB2 — Magnaporthe oryzae 70-15

Summary

MGG_06033 (MSB2) in Magnaporthe oryzae 70-15 on chromosome 3 encodes a protein with osmosensor activity. The gene is associated with the osmosensory signaling pathway via Sho1, the HOG response, signal transduction involved in filamentous growth, appressorium formation, cell polarization, vacuolar transport, fungal-type cell wall organization, invasive growth, secretion, and filamentous growth. Its product localizes to the site of polarized growth, the cell boundary, vacuolar membrane, extracellular region, and plasmalemma. MSB2 is linked to barley (Hordeum vulgare) and rice (Oryza sativa) blast disease. Studies of related genes in other species connect the MSB2 family to vascular wilt pathogens such as Verticillium dahliae and Fusarium oxysporum.
