| Research Abstract |
Mitogen-activated protein kinase (MAPK) cascades have pivotal roles in plant innate immunity. However, downstream signaling of plant defense-related MAPKs is not well understood. Here we provide evidence that Nicotiana benthamiana WRKY8 is a physiological substrate of SIPK, NTF4, and WIPK. Phosphorylation of WRKY8 increased its DNA-binding activity. MAPK-mediated phosphorylation of WRKY8 has an important role in the defense response through activation of downstream genes.
