A qPCR assay for the detection of Phytophthora abietivora, an emerging pathogen on fir species cultivated as Christmas trees.

ABSTRACT: Emerging species of the Phytophthora genus are among the most important threats to global plant biodiversity, horticulture and trade. For instance, Phytophthora root rot (PRR) of Christmas trees, mainly Fraser (Abies fraseri) and balsam (Abies balsamea) firs, is responsible for an average of 10% of the observed diseased trees in plantations. Diagnosing PRR involves isolation followed by morphological and molecular identification of the causal agents. However, these methods are rarely adapted to larger scale monitoring such as in situ detection. For these applications, molecular detection of environmental DNA (eDNA) provides the fast and high-throughput results needed. Phytophthora abietivora was associated with PRR in firs (Abies spp.) cultivated as Christmas trees in the province of Québe
