Abstract: 

Piriformospora indica is a model organism of the order Sebacinales colonizing the roots of various plant species, among them cereals and dicotyledonous plants, including Brassicaceae. The fungus protects barley plants against many root-, leaf-, and ear-infecting pathogens. We studied isolates of the Sebacinavermifera complex which have been isolated at different locations worldwide. The phylogenetic relationship between these fungal isolates was determined on the basis of nuclear genes coding for the internal transcribed spacer (ITS1-5.8S-ITS2) region. The isolates were also characterized with respect to their morphological features, such as spore size and hyphal structure as well as growth rate in different media, and further evaluated for their biological potential in barley. All the tested isolates colonized barley roots, induced growth promotion, and elicited systemic resistance against powdery mildew, though with great variations. Our results demonstrate that P. indica is the archetype of a novel fungal order that does comprise many fungi with beneficial activities on plants.
