The potato leafroll luteovirus protein of Mr 17K (pr17), which is encoded by an open reading frame on the 3' half of the viral genome, was expressed by using bacterial expression vector systems. Fusion proteins were obtained for the full-length viral protein as well as its N-terminal acidic (GST/pr17N) and C-proximal (GST/pr17C) basic domains and used in nucleic acid-binding studies. Filter-bou...

The phenotypic diversity of potato, Solanum tuberosum was assessed using morphological traits. To verify, how this diversity is distributed among the main potato varieties in the growing areas in Iran. A total of eleven potato varieties, Ramose, Sante, Shepody, Marfona, Maradona, Milova, Santana, Boren, Cosima, Granola and Agria, were evaluated under vivo and situ experimental conditions in Isf...

PURPOSE The purpose of this study was to investigate the effects of potato and lotus leaf extract intake on body composition, abdominal fat, and blood lipid concentration in female university students. METHODS A total of 19 female university students participated in this 8-week study, and they were randomly assigned into 2 groups; potato and lotus leaf extract (skinny-line) administered group...

Very little is known about sugarcane gene sequences. In this study, the aim is to identify sugarcane genes expressed in the leaf roll and the mature stem. Random DNA sequencing of cDNA clones allows the identification of genes and the development of Expressed Sequence Tags (ESTs). A total of 250 clones randomly selected from a leaf roll cDNA library and 112 from a mature stem library have been ...

Both A1 and A2 mating types of Phytophthora infestans were detected in El-Behera governorate and the surrounding area where potato and tomato were intensively cultivated during the 2005-2006 growing season. The A2 mating type constituted 14.8% of the total isolates recovered (162) while A1 mating type constituted 83.9%. A 7.4% of the total potato and tomato fields (94) surveyed yielded A2 matin...

Northern blot analysis of nucleic acid from potato plant tissues and tobacco protoplasts infected with a Scottish isolate of potato leafroll luteovirus (PLRV) detected the 6 kb genomic RNA and one subgenomic RNA species of about 2.7 kb; RNA extracted from virus particles contained only the genomic species. Blotting with small defined probes suggested that the location of the 5' end of the subge...
