A nationwide survey was performed to investigate the current incidence of viral diseases in Korean sweet potatoes for germplasm and growing fields from 2011 to 2014. A total of 83.8% of the germplasm in Korea was infected with viruses in 2011. Commercial cultivars that were used to supply growing fields were infected at a rate of 62.1% in 2012. Among surveyed viruses, the incidence of five Poty...

Agriculture is the backbone of country as it feeds human race. India’s top third crop cultivation potato. The potatoes are propagated by vegetative methods where several pathogens tend to assemble over succeeding generations causing a reduction in yield and quality crop. potato production most likely affected virus compared bacteria fungus there need develop model which diagnoses disease at ini...

A full-length cDNA copy of the genome of Potato leafroll virus (PLRV) was introduced into the genome of tobacco and potato plants by Agrobacterium tumefaciens-mediated transformation. Transgenic lines were obtained in which the transgene was readily detected by PCR with DNA extracted from T(1) tobacco seedlings and clonally multiplied potato plants. PLRV-specific genomic and sub- genomic RNAs, ...

Eight viruses infect ulluco (Ullucus tuberosus Caldus), an Andean tuber crop. Three of them, potato leafroll virus (PLRV), Andean potato latent virus, and potato virus T, also infect potato (Solanum tuberosum L.). Arracacha virus A and papaya mosaic virus, ulluco isolate (PapMV-U) infect other crops. PLRV, one of the most damaging potato viruses, was detected in healthy potato plants growing in...

Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA frac...

In sub-Saharan Africa, sweetpotato (Impomoea batatas L.) production is greatly constrained by sweetpotato virus disease (SPVD) complex. This study was conducted to assess the incidence of viruses in healthy-looking sweetpotato in Uganda and to optimise modern technologies for virus diagnosis. A collection of healthy-looking sweetpotato vines from central Uganda were serologically assayed for sw...

Photochemical decontamination (PCD) of platelet concentrates, with adequate preservation of platelet function, has been shown using 8-methoxypsoralen (8-MOP) and long wavelength UV light (UVA). To further evaluate this technique, models for the inactivation of pathogenic human cell-associated viruses and integrated proviral sequences are required. We have assessed the ability of the PCD techniq...

Potato, Solanum tuberosum L., is one of the world’s principal food crops. Important potato insect pests include Colorado potato beetle, Leptinotarsa decemlineata Say, potato tuberworm, Phthorimaea operculella (Zeller), and aphids, especially as they transmit potato leafroll virus and potato virus Y. Management of insect pests of potato relies almost entirely on chemical insecticides. Potato bre...
