Abstract: 
The root endophytic Basidiomycete Piriformospora indica forms a specific type of mycorrhiza symbiosis with a broad spectrum of plant species, including the Brassicaceae. A recent report on the interaction of P. indica with Arabidopsis thaliana suggests that the fungus induces a mode of resistance to microbial pathogens reminiscent of Induced Systemic Resistance (ISR) first discovered with non-pathogenic rhizobacteria. The characteristics of P. indica mediated resistance are the dependency on JA-signalling and the cytosolic function of the master regulator protein Non-expressor-of-PR-genes 1 (NPR1), a low level of altered systemic gene expression in leaves before pathogen challenge, the induction of the JA-inducible marker gene vegetative storage protein 1 (VSP1) after pathogen challenge, and an independency of the resistance phenotype from salicylate biosynthesis and signalling. We discuss here two more factors regarding the P. indica-mediated ISR response: the role of the plant hormone ethylene as well as a possible contribution of the recently discovered close association of P. indica with the alpha-proteobacterium Rhizobium radiobacter.
