Mining the effector repertoire of the biotrophic fungal pathogen Ustilago hordei during host and non-host infection.

ABSTRACT: The success of plant-pathogenic fungi mostly relies on their arsenal of virulence factors which are expressed and delivered into the host tissue during colonization. The biotrophic fungal pathogen Ustilago hordei causes covered smut disease on both barley and oat. In this study, we combined cytological, genomics and molecular biological methods to achieve a better understanding of the molecular interactions in the U. hordei-barley pathosystem. Microscopic analysis revealed that U. hordei densely colonizes barley leaves on penetration, in particular the vascular system. Transcriptome analysis of U. hordei at different stages of host infection revealed differential expression of the transcript levels of 273 effector gene candidates. Furthermore, U. hordei transcriptionally activates core eff
