A Novel Pathosystem With the Model Plant Arabidopsis thaliana for Defining the Molecular Basis of Taphrina Infections.

ABSTRACT: Plant-associated yeasts modulate host immunity to promote or prevent disease. Mechanisms of yeast perception by the plant innate immune system remain unknown, with progress hindered by lack of a model system with the model plant Arabidopsis thaliana (Arabidopsis). A yeast strain of Taphrina tormentillae, named M11, was previously isolated from wild Arabidopsis. Taphrina have been found on many non-host plants, and their complex ecology remains understudied. Here, the interaction of M11 with Arabidopsis was characterised. Infection of Arabidopsis with the birch pathogen T. betulina, used as a non-host control, triggered typical defence activation features but did not multiply, demonstrating Arabidopsis had immunity against a non-adapted yeast. M11 triggered attenuated defence activation fea
