Polymorphic SSR markers for Plasmopara obducens (Peronosporaceae), the newly emergent downy mildew pathogen of Impatiens (Balsaminaceae).
PREMISE OF THE STUDY Simple sequence repeat (SSR) markers were developed for Plasmopara obducens, the causal agent of the newly emergent downy mildew disease of Impatiens walleriana. METHODS AND RESULTS A 202-Mb draft genome assembly was generated from P. obducens using Illumina technology and mined to identify 13,483 SSR motifs. Primers were synthesized for 62 marker candidates, of which 37 ...

متن کاملHaplotype characterization and markers at the barley Mlo powdery mildew resistance locus as tools for marker-assisted selection.
Recessive mlo alleles of the barley Mlo gene confer resistance to almost all known isolates of the powdery mildew fungal pathogen targeting barley (Hordeum vulgare). To characterize haplotypes present in the Mlo chromosomal region of cultivated Mlo and mlo barley genotypes, we conducted a polymorphism search in 3 predicted low-copy sequence regions adjacent to the Mlo gene by examining a sample...
متن کاملComponents of Quantitative Resistance to Downy Mildew (plasmopara Halstedii) in Sunflower (helianthus Annuus)
Components of quantitative resistance in sunflower (Helianthus annuus) to Plasmopara halstedii, the pathogen causing downy mildew, were investigated. Percentage infection, latent period, sporulation density and reduction of hypocotyl length were compared on two sunflower lines showing different levels of quantitative resistance in the field infected with different P. halstedii strains of races ...
متن کاملInter-isolate variation for virulence in Plasmopara halstedii (sunflower downy mildew) from Hungary
A total of 82 isolates of Plasmopara halstedii, collected from all production areas of Hungary between 1976 and 1993, were assessed for their virulence pattern on a standard set of sunfiower differentials under glasshouse conditions. The isolates were classified into six pathogenic races each representing a particular virulence phenotyjje. From 1976 until 1988 all the isolates were found to be ...
