The penetration ring is a novel infection structure formed by the penetration peg for invading plant cell membrane in rice blast fungus

This paper identifies a novel penetration ring formed by secreted proteins in the rice blast fungus after cell wall penetration, which persists at the plasma membrane interface during invasion.

Magnaporthe oryzae CK2 is involved in rice blast pathogenesis and accumulates in nuclei, nucleoli, at septal and appressoria pores and forms a large ring structure in appressoria

This study investigates the localization and role of CK2 in Magnaporthe oryzae during growth and infection, finding it localizes to nuclei, nucleoli, septal pores, and appressoria with regulatory functions.
