Potato mop-top pomovirus (PMTV) is one of a few viruses that can move systemically in plants in the absence of the capsid protein (CP). Pomoviruses encode the triple gene block genetic module of movement proteins (TGB 1, 2, and 3) and recent research suggests that PMTV RNA is transported either as ribonucleoprotein (RNP) complexes containing TGB1 or encapsidated in virions containing TGB1. Furt...

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...

background: potyviruses are accounted for 40% of viral diseases of various crops including vegetables and legumes. potyviruses can be transmitted through plant sap, seeds and many aphid species. due to ease of spread of these viruses detection of such viruses are crucial as to the control of the incited diseases. objectives: this study compared the efficiencies of two couples of primers in thei...

the use of healthy planting material is an important prerequisite for controlling destructive viral diseases in potato production. virus elimination methods such as meristem culture and thermotherapy are usually used to produce the nucleus stock of healthy planting material. here, we report a new technique of electrotherapy for elimination of two potyviruses, potato virus a (pva), and potato vi...

this research was performed in order to study and diagnose potato virus y,potyvirus (pvy), potato virus x,potexvirus (pvx), potato virus s,carlavirus (pvs), potato virus a,potyvirus(pva) and potato leafroll luteovirus (plrv) on tubers and leaves of different potato varieties, namely, solea, safran, floris, proventa, milva, universa, lady olympia, vangogh, and marabel grown in afyon region of tu...

The study was carried out in two intensive potato growing areas (Rangpur and Munshigonj) to estimate the technical efficiency of potato producers and to describe the level of variation in potato productivity due to differences in input use. Data were collected from 60 farmers (30 farmers from each district) using simple random sampling technique. Average technical efficiency was 86% implying th...
