Novel Regulators and Their Epistatic Networks in Arabidopsis' Defence Responses to Alternaria alternata Infection.

ABSTRACT: Necrotrophic pathogens cause serious threats to agricultural crops, and understanding the resistance genes and their genetic networks is key to breeding new plant cultivars with better resistance traits. Although Alternaria alternata causes black spot in important leafy brassica vegetables, and leads to significant loss of yield and food quality, little is known about plant-A. alternata interactions. In this study, we used a unique and large collection of single, double and triple mutant lines of defence metabolite regulators in Arabidopsis to explore how these transcription factors and their epistatic networks may influence A. alternata infections. This identified nine novel regulators and 20 pairs of epistatic interactions that modulate Arabidopsis plants' defence responses to A. alterna
