Diversity Among Potato virus Y Isolates Obtained from Potatoes Grown in the United States.
ABSTRACT Potato field isolates (Solanum tuberosum) of Potato virus Y (PVY) collected from the midwestern and western United States were characterized using serological, molecular, and biological assays. PVY field isolates were grouped into the previously defined categories: PVY(O), European PVY(NTN), North American PVY(NTN), and PVY(N:O) recombinant and four previously undefined groups. Studies...
متن کاملTECHNICAL SHEET no. 11 VIRUSDETECTION: VARIABILITY ANALYSIS OF PVY STRAINS GENERAL
PVY is a member of the Potyviridae, the largest plant virus family. For general information on PVY see the Web Site (life.anu.edu.au/viruses/ICTVdB/57010001.htm). Currently, three main strains of PVY are know. (i) PVY (ordinary or common strain) is widely distributed throughout the potato growning areas of the world. This strain induces mild to severe mosaic and can cause stem necrosis in some ...
متن کاملMapping Loci That Control Tuber and Foliar Symptoms Caused by PVY in Autotetraploid Potato (Solanum tuberosum L.)
Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability, and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with...
متن کاملDevelopment of a multiplex AmpliDet RNA assay for simultaneous detection and typing of potato virus Y isolates.
A multiplex AmpliDet RNA assay was developed for the specific detection of potato virus Y (PVY), and for the differentiation of the PVY(N), PVY(O/C) strains and the tuber necrotic isolates (PVY(NTN)). The assay is based on the generic amplification of a region within the coat protein coding region of all known PVY isolates by nucleic acid sequence-based amplification (NASBA) and strain-specific...
