A Meloidogyne incognita effector MiISE5 suppresses programmed cell death to promote parasitism in host plant
Abstract Root-knot nematodes (RKNs) are highly specialized parasites that interact with their host plants using a range of strategies. The esophageal glands are the main places where nematodes synthesize effector proteins, which play central roles in successful invasion. The Meloidogyne incognita ef...

Abstract Root-knot nematodes (RKNs) are highly specialized parasites that interact with their host plants using a range of strategies.
