A major justification for taxonomic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in a representative subset of the group. Similarly, populations in similar environments are expected to be more alike than populations in divergent environments. Consequently, it is logical to assume that taxonomic relationships and biogeographic...

Potato virus Y (PVY) the type member of the genus Potyvirus, occurs world-wide as isolates which differ in host range and the type of symptoms caused. The sequences of a 5' segment of viral RNA overlapping the 5' non-translated region (5'NTR) alone (ten isolates) or the 5'NTR and the adjacent P1 coding region (eight isolates) were established. These data were used to quantify the polymorphism i...

Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement st...

Abstract Potato virus Y (PVY) is one of the main diseases tobacco (Nicotiana tabacum). Recent studies indicated that Va gene (Ntab0942120) determines susceptibility crop to PVY, and product interacts with PVY genome-linked protein (VPg) initiate genome translation process, which ultimately leads systemic infection by virus. In this research, cultivar LJ911 was used as receptor material for edit...

The potential effect of genetic modification on nutritional properties of potatoes transformed to improve resistance to a necrotic strain of Potato virus Y was determined in a rat experiment. Autoclaved tubers from four transgenic lines were included to a diet in the amount of 40% and compared with the conventional cv. Irga. The experiment lasted 3 weeks and special attention was paid to nutrit...

SIEVERT, R. C. 1978. Effect of potato virus Y and tobacco mosaic virus on field-grown burley tobacco. Phytopathology 68: 823-825. Yield, grade index, crop index, value per kilogram, and tobacco had less nicotine and TMV-infected tobacco had less value per hectare were reduced when Burley 37 became a-amino nitrogen, but tobacco infected with TMV+PVY had infected with tobacco mosaic virus (TMV), ...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...
