(Submitter supplied) Powdery mildew (Erysiphe necator) is a widespread and economically important disease of grapevines. Large quantities of fungicides are used for its control, accelerating the incidence of fungicide-resistance. A shotgun approach was applied to sequence and assemble the E. necator genome of five isolates, and RNA-seq and comparative genomics were used to predict and annotate protein-coding genes. In addition, a collection of 98 E. more...

(Submitter supplied) Powdery mildew (PM) is one of the most important and widespread plant diseases caused by obligate biotrophic Ascomycete fungi in the order of Erysiphales. Monocot PM fungi such as Blumeria graminis f.sp. hordei (Bgh) infectious on barley and B. graminis f.sp. tritici (Bgt) infectious on wheat exhibit high-level of host-specialization. By contrast, many dicot PM fungi display rather broad host ranges. more...

(Submitter supplied) Disease resistance (R) genes encoding intracellular nucleotide-binding domain and Leucine-rich repeat proteins (NLRs) are key components of the plant innate immune system and typically detect the presence of isolate-specific avirulence (AVR) effectors from pathogens. NLRs define the fastest evolving gene family of flowering plants and are often arranged in gene clusters containing multiple paralogs, contributing to extensive copy number and allele-specific NLR variation within a host species. more...

(Submitter supplied) Septoria leaf blotch is a worldwide threat for wheat and mainly controlled by the application of synthetic fungicides. The fungal pathogen responsible for this disease, Zymoseptoria tritici, was shown as highly adaptable to its host plant, but also to fungicide challenge. Over the past decades it developed resistance to most fungicides due to target site modifications. Recently isolated strains showed cross-resistance to diverse fungicides and to unrelated drugs, suggesting a resistance mechanism that seems rarer in phytopathogenic fungi, known as multidrug resistance (MDR) in other organisms. more...

(Submitter supplied) Grape powdery mildew (PM), caused by the biotrophic ascomycete Erysiphe necator, is a devastating fungal disease that affects most Vitis vinifera cultivars. We have previously identified a panel of V. vinifera accessions from Central Asia with partial resistance to PM that possess a Ren1-like local haplotype. In this study we show that in addition to the typical Ren1-associated late post-penetration resistance, these accessions display a range of different levels of disease development suggesting that alternative alleles or additional genes contribute to determining the outcome of the interaction with the pathogen. more...

(Submitter supplied) Hybridization between Cottus rhenanus and C. perifretum has resulted in an evolutionary young hybrid lineage of invasive Cottus that has colonized a new habitat where the parental species are not found (Nolte et al. 2005; Proc. R. Soc. B 272: 2379–2387). This CGH array was designed to screen for copy number variation among Cottus species and to find gene duplicates that are unique to the hybrid lineage (see also Dennenmoser et al. more...

(Submitter supplied) Calibration array used to assess probe specific binding behaviour across eight different amounts of DNA starting material. This calibration step was performed to select one best out of three probes per gene based on probe responsiveness on increasing DNA staring material. It was further used to calibrate a subsequent microarray experiment to account for probe specific binding behaviour as part of the normalization process (see also Dennenmoser et al. more...
