Interaction of NIMIN1 with NPR1 modulates PR gene expression in Arabidopsis.

The Plant cell - 1 Apr 2005

Weigel Ralf R, Pfitzner Ursula M, Gatz Christiane

Abstract excerpt

The Arabidopsis thaliana NONEXPRESSER OF PR GENES1 (NPR1, also known as NIM1) protein is an essential positive regulator of salicylic acid (SA)-induced PATHOGENESIS-RELATED (PR) gene expression and systemic acquired resistance (SAR). PR gene activity is regulated at the level of redox-dependent nuclear transport of NPR1. NPR1 interacts with members of the TGA family of transcription factors that are known to bind...
