TcNPR3 from Theobroma cacao functions as a repressor of the pathogen defense response.

BMC plant biology - 6 Dec 2013

Abstract excerpt

BACKGROUND: Arabidopsis thaliana (Arabidopsis) NON-EXPRESSOR OF PR1 (NPR1) is a transcription coactivator that plays a central role in regulating the transcriptional response to plant pathogens. Developing flowers of homozygous npr3 mutants are dramatically more resistant to infection by the pathogenic bacterium Pseudomonas syringae, suggesting a role of NPR3 as a repressor of NPR1-mediated defense response with...
