Comparative epidemiology of Pyrenopeziza brassicae (light leaf spot) ascospores and conidia from Polish and UK populations
Karolewski, Z.; Evans, N.; Fitt, Bruce D.L.; Baierl, A.; Todd, A.D.; Foster, S.J. (2004-02)Despite differences in climate and in timing of light leaf spot epidemics between Poland and the UK, experiments provided no evidence that there are epidemiological differences between populations of Pyrenopeziza brassicae ... -
Development of PCR based diagnostic techniques for the two mating types of Pyrenopeziza brassicae (light leaf spot) on winter oilseed rape (Brassica napus ssp. oleifera)
Foster, S.J.; Singh, G.; Fitt, Bruce D.L.; Ashby, A.M. (1999-08)Two sets of PCR primers were designed from DNA sequence which flanked the 3' end of the Pyrenopeziza brassicae mating type idiomorphs (MAT-1 and MAT-2). The first set of primers facilitated the amplification of a 750 bp ... -
Improved PCR-based assays for pre-symptomatic diagnosis of light leaf spot and determination of mating type of Pyrenopeziza brassicae on winter oilseed rape
Foster, S.J.; Ashby, A.M.; Fitt, Bruce D.L. (2002-05)An existing PCR-based method for diagnosis of the winter oilseed rape (Brassica napus ssp oleifera) fungal pathogen Pyrenopeziza brassicae (cause of light leaf spot) was improved by the development of a pair of primers ... -
Isolation and characterisation of the mating-type (MAT) locus from Rhynchosporium secalis
Foster, S.J.; Fitt, Bruce D.L. (2003-12-31)The mating-type (MAT) genes from Rhynchosporium secalis were isolated using PCR-based methods. Characterisation of the MAT idiomorphs suggests that R. secalis is closely related to the discomycetes Pyrenopeziza brassicae ... -
Visual and PCR assessment of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) cultivars
Karolewski, Z.; Fitt, Bruce D.L.; Latunde-Dada, A.O.; Foster, S.J.; Todd, A.D.; Downes, K.; Evans, N. (2006-06)Methods to assess light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape cultivars were compared in laboratory, controlled-environment and field experiments. In controlled-environment experiments with seedling ...
