Mitochondrial loci enable specific qPCR detection of the pathogen causing contemporary impatiens downy mildew epidemics

• Christopher Miller

Impatiens downy mildew (IDM) illness is a main constraint on the manufacturing of Impatiens walleriana, a preferred and economically vital floriculture plant. IDM is attributable to the biotrophic oomycete Plasmopara destructor that emerged as a pathogen of I. walleriana within the 2000s. To allow P. destructor detection and quantification, a hydrolysis probe-based quantitative PCR diagnostic assay was developed based mostly on distinctive…
