Open AccessThe AvrPm3-Pm3 effector-NLR interactions control both race-specific resistance and host-specificity of cereal mildews on wheat
The wheat Pm3 resistance gene against the powdery mildew pathogen occurs as an allelic series encoding functionally different immune receptors which induce resistance upon recognition of isolate-specific avirulen...

Open AccessDNA transposon activity is associated with increased mutation rates in genes of rice and other grasses
DNA (class 2) transposons are mobile genetic elements which move within their ‘host’ genome through excising and re-inserting elsewhere. Although the rice genome contains tens of thousands of such elements, th...

Open AccessHybridization of powdery mildew strains gives rise to pathogens on novel agricultural crop species
Beat Keller, Thomas Wicker and colleagues compare the genomes of 46 isolates of powdery mildew, Blumeria graminis. They find that B. graminis f. sp. triticale, a pathogen growing on triticale (a wheat × rye hybri...

Open AccessThe making of a genomic parasite - the Mothra family sheds light on the evolution of Helitrons in plants
Helitrons are Class II transposons which are highly abundant in almost all eukaryotes. However, most Helitrons lack protein coding sequence. These non-autonomous elements are thought to hijack recombinase/heli...

Open AccessRiTE database: a resource database for genus-wide rice genomics and evolutionary biology
Comparative evolutionary analysis of whole genomes requires not only accurate annotation of gene space, but also proper annotation of the repetitive fraction which is often the largest component of most if not...

Open AccessGenome-wide comparison of Asian and African rice reveals high recent activity of DNA transposons
DNA (Class II) transposons are ubiquitous in plant genomes. However, unlike for (Class I) retrotransposons, only little is known about their proliferation mechanisms, activity, and impact on genomes. Asian and...

Open AccessThe wheat powdery mildew genome shows the unique evolution of an obligate biotroph
Thomas Wicker and colleagues report the whole-genome sequencing of four wheat powdery mildew (Blumeria graminis forma specialis tritici) isolates from different geographic regions. Their comparative genomic analy...
