Necrosis-inducing secreted protein 1 (Nis1) is a fungal secreted effector that induces necrotic lesions in plants it infects (2). This protein interacts with the host receptor-like kinases and inhibits their kinase activity [1].

1: Conserved fungal effector suppresses PAMP-triggered immunity by targeting plant immune kinases. Irieda H, Inoue Y, Mori M, Yamada K, Oshikawa Y, Saitoh H, Uemura A, Terauchi R, Kitakura S, Kosaka A, Singkaravanit-Ogawa S, Takano Y; Proc Natl Acad Sci U S A. 2019;116:496-505. PMID:30584105

2: Cell death of Nicotiana benthamiana is induced by secreted protein NIS1 of Colletotrichum orbiculare and is suppressed by a homologue of CgDN3. Yoshino K, Irieda H, Sugimoto F, Yoshioka H, Okuno T, Takano Y; Mol Plant Microbe Interact. 2012;25:625-636. PMID:22352720
