Potato virus Y has emerged as a threatening problem in all potato growing areas around the globe. PVY reduces the yield and quality of potato cultivars. During the last 30 years, significant genetic changes in PVY strains have been observed with an increased incidence associated with crop damage. In the current study, computational approaches were applied to predict Potato derived miRNA targets...

One of the most severe symptoms caused by compatible plant-virus interactions is systemic necrosis, which shares common attributes with the hypersensitive response to incompatible pathogens. Although several studies have identified viral symptom determinants responsible for systemic necrosis, mechanistic models of how they contribute to necrosis in infected plants remain scarce. Here, we examin...

SUMMARY The complete nucleotide sequence of the genomic RNA of the potyvirus potato virus Y strain N (PVYn) was obtained from cloned cDNAs. This sequence is 9704 nucleotides long and can encode a polyprotein of 3063 amino acids. The positions of the cleavage sites at the N terminus of the capsid and cytoplasmic inclusion proteins have been determined. Other putative protein cleavage sites have ...

A mechanically transmissible virus causing leaf mottling and ringspotting of Passiflora edulis var. flavicarpa in the Ivory Coast is described. Its particles are flexuous rods 810-830 nm long and 15 nm wide. It infects mainly species of Passifloraceae and Leguminosae; Passiflora foetida is a good diagnostic host. Aphis gossypii and Aphis spiraecola transmit the virus after brief acquisition fee...

Abstract Brazilian potato production is based on cultivars originating from the USA and Europe; however, these were developed under different environmental conditions than those found in Brazil. The aim of this study was to evaluate adaptability stability 18 clones (MLG), by Universidade Federal de Lavras, four six environments state Minas Gerais, following traits evaluated: marketable tuber yi...

Potato is an important food crop worldwide and grown in a large number of countries. As such, the under disease pressures need for selecting resistance genes during breeding programs essential. Of particular importance within Australia other parts world potyvirus, virus Y (PVY). In this paper, three commonly used PVY markers, M45, RYSC3 M6, were evaluated using existing genomic resources phenot...
