Biological Roles Of Small Rnas Expressed During Infection Of Barley By The Obligate Fungal Biotroph, Blumeria Graminis F. Sp. Hordei, Matthew Robert Hunt
Graduate Theses and Dissertations
Plants and their pathogens have constantly co-evolving mechanisms that determine infection success. Small RNAs (sRNAs) of 18-30 nucleotides can have a large effect regulating plant defense responses as well as fungal virulence factors. The goal of this project was to understand how sRNAs regulate gene expression both for species of origin, as well as trans-kingdom sRNA communication between barley and Blumeria graminis f. sp. hordei (Bgh), the causal agent of barley powdery mildew. To accomplish this goal we examined Bgh sRNA expression over a time course representing the key stages of Bgh infection of barley (appressorium formation, penetration of epidermal ...
