The complete DNA genome of sweet potato leaf curl virus (SPLCV) from samples obtained from eight regions was amplified by PCR and characterized in this study. The DNA genome of one group (SPLCV Korea group 1) consisted of 2828 nucleotides and that of the second group (SPLCV Korea group 2) consisted of 2829 nucleotides. Sequence comparisons showed that the genome sequences of SPLCV Korea isolate...

Potato virus A (PVA) particles were bombarded with thermally activated tritium atoms, and the intramolecular distribution of the label in the amino acids of the coat protein was determined to assess their in situ steric accessibility. This method revealed that the N-terminal 15 amino acids of the PVA coat protein and a region comprising amino acids 27 to 50 are the most accessible at the partic...

EPPER vein-banding virus causes a troublesome disease of cultivated peppers I? (Capsicum spp.) in Puerto Rico (ADSUAR 1940) and in Trinidad. A rather similar disease occurs in Hawaii ( KIKUTA 1947). Serological investigations (PEREZ and ADSUAR 1955) indicate that the virus responsible for the West Indian disease is a strain of potato virus Y. In Trinidad, DALE (1954) found that three distinct s...

Potato (Solanum tuberosumL.) late blight, caused byPhytophthora infestans (Mont.) de Bary, is one of the most damaging diseases in any crop. Deployment of resistant varieties is the most effective way to control this disease. However, breeding for late blight resistance has been a challenge because the race-specific resistance genes introgressed from wild potato S. demissum Lindl. have been sho...
