There is a large diversity of genetically defined resistance genes in bread wheat against the powdery mildew pathogen Blumeria graminis (B. g.) f. sp. tritici. Many confer race-specific resistance to this pathogen, but until now only the mildew avirulence gene AvrPm3a2/f2 that is recognized by Pm3a/f was known molecularly. We performed map-based cloning and genome-wide association studies to is...

Three members of the Puccinia genus, Pucciniatriticina (Pt), Pstriiformis f.sp. tritici (Pst), and Pgraminis f.sp. tritici (Pgt), cause the most common and often most significant foliar diseases of wheat. While similar in biology and life cycle, each species is uniquely adapted and specialized. The genomes of Pt and Pst were sequenced and compared to that of Pgt to identify common and distingui...

To study protein ubiquitination pathways in the interaction of barley (Hordeum vulgare) with the powdery mildew fungus (Blumeria graminis), we measured protein turnover and performed transient-induced gene silencing (TIGS) of ubiquitin and 26S proteasome subunit encoding genes in epidermal cells. Attack by B. graminis hyperdestabilized a novel unstable green fluorescent protein fusion that cont...

Rust fungi (Basidiomycetes of the order Uredinales) are obligate biotrophs that grow and reproduce only in living plant tissue. There are on the order of 5000 or more species of rust fungi that collectively cause disease on most crops, ornamentals, and many other plants. For example, rusts caused by Puccinia species are some of the most important diseases of wheat and other small grain crops wo...
