Specific primers for coat protein gene of PLRV (PLRV-CP), coat protein gene of PVY (PVY-CP) and coat protein gene of PVX (PVX-CP) was used for the CP genes according to Shalaby et al.
The same has been suggested by Ibaba and Gubba (2012) for existence of South American PVY isolates in KwaZulu- Natal.
2011) reportaron la deteccion de PVY en diferentes organos de plantas infectadas, el cual presento una distribucion heterogenea con mayor acumulacion en los foliolos; para nuestro caso la mayor concentracion se presento en la zona aerea; esto podria ser una estrategia de dispersion, porque al mantenerlo en esta zona, el virus quedaria mas accesible a la mosca blanca, contribuyendo de esta manera con la dispersion del mismo, este aspecto no habia sido estudiado previamente en PYVV, pero si en otros virus como por ejemplo Carnation etched ring virus (CERV, Caulimoviridae) y Carnation vein mottle virus (CVMV, Potyviridae), que son transmitidos por miembros de la familia Aphididae, estos presentaron una menor acumulacion viral en la zona radical (Sanchez-Navarro et al.
Los hallazgos presentados en este trabajo y otros realizados recientemente para PVY y PLRV (Gil et al.
Baronesa plants expressing the PVY CP-gene do not have morphological attributes or tuber production characteristics that differ from those of the wild-type cultivar, indicating that the introduction of the virus protective cape capsid gene does not alter other characteristics in the original genotype.
Esse resultado tambem confirma a eficacia do marcador RYSC3 na identificacao de genotipos com resistencia extrema ao PVY, como mencionado por RIBEIRO et al.
Transmitted by aphids to plants, PVY threatens not only potato, but also other crops such as tomato, pepper, and tobacco.
The reemergence of Potato Virus Y (PVY) in potato seed stock is of great concern to farmers because insecticides used to control the aphids that vector PVY do not effectively decrease transmission of the disease.
Los reportes de los efectos del PVY en los cultivos de tomate son muy variables; asi por ejemplo Thomas y McGrath (1988) indican que este virus ha causado epidemias en Australia con niveles de infeccion hasta del 100% y perdidas del 50% en la produccion de frutos, mientras que Morel et al.
PVY is transmitted in a non-persistent manner and is acquired and inoculated during brief probes by aphids, including the alatae of many species that do not colonize potato.
In this study observations of mosaic patterns on leaves stunting of the plant leaf malformations on potato plants in this region during field surveys indicated the presence of PVY in South-West region in Turkey.
