Potato leafroll virus is a member of the polerovirus genus. The isometric virion is formed by a coat protein encapsidating single-stranded, positive-sense, mono-partite genomic RNA with covalently attached viral protein at the 5' end. The coat protein of the virus exists in two forms: i) a 23 kDa protein, the product of the coat protein gene, and ii) a 78 kDa protein, the product of the coat pr...

Viral diseases have been a major limiting factor threating sustainable potato (Solanum tuberosum L.) production in Pakistan. Surveys were conducted to serologically quantify the incidence of RNA viruses infecting potato; Potato virus X (PVX), Potato virus Y (PVY), Potato virus S (PVS), Potato virus A (PVA), Potato virus M (PVM) and Potato leaf roll virus (PLRV) in two major potato cultivars (De...

potato is one of the most essential nutritious food products for many people in the world. it is very important in the food basket of the iranian families as well. ardabil, isfahan and hamedan are the main potato growing provinces in iran. hamedan province ranks first with respect to yield. regarding the existing high potential in this province, an economic evaluation of this product would be i...

The growth in Internet connectivity at the Autonomous System (AS) level and the practice of ”hot potato” routing has increased the possibility of interaction between intradomain and interdomain traffic engineering (TE). Hot potato routing occurs when a router inside an AS knows of multiple exit points out of the AS towards a destination, and selects the one that is ”closest” to it. The closenes...

A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

The creation of artificial metabolic sinks in plants by genetic engineering of key branch points may have serious consequences for the metabolic pathways being modified. The introduction into potato of a gene encoding tryptophan decarboxylase (TDC) isolated from Catharanthus roseus drastically altered the balance of key substrate and product pools involved in the shikimate and phenylpropanoid p...
