Harnessing the power of comparative genomics to support the distinction of sister species within and development of highly specific detection of causing citrus black spot by real-time PCR.

Citrus crops are affected by many fungal diseases. Among them, Citrus Black Spot caused by the ascomycete is particularly economically damaging wherever it occurs. Many other species of are described on Citrus, but only is considered a quarantine pest on the European continent.

Pathogenicity and Host Range of -A Soil-Borne Oomycete Recently Discovered in the UK.

During a survey of oomycetes in ornamental plants carried out at the University of Aberdeen in 2014-2015, was isolated from a specimen of 'Lanarth', the first report of this oomycete in the UK (and in Europe). Pathogenicity of a isolate was examined using a range of plant species. Inoculations were carried out under controlled conditions in the absence of other and species, on (soya bean), (common bean), (blue lupin), (cucumber) and .

Application of Real-Time PCR for the Detection and Quantification of Oomycetes in Ornamental Nursery Stock.

Numerous and disease outbreaks have occurred in Europe following inadvertent introduction of contaminated ornamental plants. Detection and identification of pathogens are crucial to reduce risks and improve plant biosecurity in Europe and globally. Oomycete diversity present in roots and compost was determined in 99 hardy woody plants bought from nurseries, retailers and internet sellers, using both isolations and molecular analyses.
