Genome sequencing of a Plum pox virus isolate infecting Prunus domestica cv D'Agen in Argentine using the ONT platform

Abstract

Plum pox virus ( the causal agent of Sharka disease, affects Prunus fruit trees It was first detected in Argentina in San Juan (2006) and Mendoza (2007) provinces, mainly in Japanese plum, European plum, and apricot varieties In acute infections, PPV causes a severe reduction in yield and fruit quality, making the produce unsuitable for consumption, industrialization, and export ..(fig 1 The genome of the virus (fig 2 is from Potyvirus group and has different strains or genomics variants usually specific to the host, region, and vector (aphid transmitted), causing varying degrees of damage, with some affecting up to 80 of susceptible cultivars 3.
