small RNA from barley powdery mildew

The aim of this study is to determine the small RNA (sRNA) produced by barley and Blumeria graminis f. sp. hordei. Infected leaves were dissected to separate infection structures, and extracellular vesicles from the plant apoplast. The samples analysed were: epiphytic mycelium and spores; infected barley epidermis; haustoria; microsomes from infected epidermis; extracellular vesicles from infected or non-infected barley leaves.
