Mitochondrial Genome Resource for Peronospora sparsa, the Oomycete Causing Dry Berry Disease in Rubus, from a 19th-Century Herbarium Specimen and a Modern Isolate
We report the first complete mitochondrial genomes of P. sparsa, assembled from a historical herbarium specimen collected in 1899 and from a contemporary isolate obtained in 2021. These mitogenomic resources provide a foundation for improved molecular diagnostics, enable reliable discrimination among species within the Sparsa clade, and facilitate molecular surveillance and epidemiological studies of this economically important plant pathogen.
