Occurrence and genetic diversity of the Plasmopara halstedii virus in sunflower downy mildew populations of the world.

Fungal biology - 1 Mar 2015

Grasse Wolfgang, Spring Otmar

Abstract excerpt

Plasmopara halstedii virus (PhV) is a ss(+)RNA virus that exclusively occurs in the sunflower downy mildew pathogen Plasmopara halstedii, a biotrophic oomycete of severe economic impact. The virus origin and its genomic variability are unknown. A PCR-based screening of 128 samples of P. halstedii from five continents and up to 40 y old was conducted. PhV RNA was found in over 90 % of the isolates with no...
