First Report of Prunus necrotic ringspot virus in Peach in Mexico

Plant Disease, 2008
Peach (Prunus persica (L.) Batsch) is one of the most important fruit crops in the temperate regions of Mexico. In 2006, during a survey conducted in commercial peach orchards in Puebla, Mexico for viral diseases, many trees were observed with foliar symptoms that included yellow mottle, ringspot, line patterns, and mosaic.

Virulence and molecular polymorphism of Prunus necrotic ringspot virus isolates.

Journal of General Virology, 1998
Prunus necrotic ringspot virus (PNRSV) occurs as numerous strains or isolates that vary widely in their pathogenic, biophysical and serological properties. Prior attempts to distinguish pathotypes based upon physical properties have not been successful; our approach was to examine the molecular properties that may distinguish these isolates.

Molecular Variability Among Isolates of Prunus Necrotic Ringspot Virus from Different Prunus spp. [PDF]

Phytopathology®, 1999
Viral sequences amplified by polymerase chain reaction from 25 isolates of Prunus necrotic ringspot virus (PNRSV), varying in the symptomatology they cause in six different Prunus spp., were analyzed for restriction fragment polymorphisms. Most of the isolates could be discriminated by using a combination of three different restriction enzymes.
