Beet curly top Iran virus (BCTIV) is a divergent geminivirus with biological properties similar to those of curtoviruses; however, the virus is distinct from curtoviruses phylogenetically and in its genome organisation. The replication-associated protein is phylogenetically more closely related to those of mastreviruses than to those of curtoviruses whereas(More)
Six hundred and one symptomatic potato samples were collected from nine provinces in Iran. Screening by double-antibody sandwich enzyme linked immunosorbent assay using a potato virus X (PVX) together with a few potyviruses polyclonal antibodies, produced positive reactions in 4.3 % of samples against PVX. Based on symptoms on different test plant, the(More)
The ongoing global spread of Tomato yellow leaf curl virus (TYLCV; Genus Begomovirus, Family Geminiviridae) represents a serious looming threat to tomato production in all temperate parts of the world. Whereas determining where and when TYLCV movements have occurred could help curtail its spread and prevent future movements of related viruses, determining(More)
Beet curly top Iran virus (BCTIV) is a major pathogen of sugar beet in Iran. In order to study diversity of BCTIV, we sampled 68 plants in Iran during the summer of 2010 with curly top disease symptoms on beans (Phaseolus vulgaris), cowpeas (Vigna unguiculata), tomatoes (Solanum lycopersicum L.), sea beets (Beta vulgaris subsp. maritima), and sugar beets(More)
Turnip curly top virus (TCTV) is a unique geminivirus that has recently been characterised as infecting turnips in Iran. The genome of TCTV shares <68 % pairwise identity with other geminiviruses and has a genome organisation similar to that of curtoviruses and topocuvirus. The replication-associated protein (Rep) bears the highest similarity to curtovirus(More)
Among the reported begomoviruses which cause tomato leaf curl disease (TLCD) in Iran, Tomato leaf curl Palampur virus (ToLCPMV) was the first bipartite begomovirus to be detected in tomato in 2006 in Hormozgan Province (southern Iran). Following this, the ToLCPMV incidence has progressively increased amongst several cultivated plants and to new geographical(More)
Turnip curly top virus (TCTV) is the only member of the newly established genus Turncurtovirus (family Geminiviridae). As part of an ongoing study to identify additional plant hosts and the diversity of turncurtoviruses, between 2012 and 2014, we sampled symptomatic turnip plants and other crops in the provinces Fars and Khorasan Razavi (southern and(More)
Watermelon chlorotic stunt virus (WmCSV) and tomato leaf curl Palampur virus (ToLCPMV) are limiting factors for cucurbit production in south and southeastern Iran. ToLCPMV infects all cucurbit crops (except watermelons) whereas WmCSV is somewhat limited to watermelon, causing detrimental effects on fruit production. In a survey, we detected WmCSV in all(More)
A survey was carried out to determine the extent of Potato virus V (PVV) infection, together with other potyviruses, in Iran in both commercial and local potato varieties. We found a low incidence of PVV in commercial varieties compared to a local potato cultivar Zardi, in which we noted a PVV infection up to ~32.9 %. We determined the genomic sequence(More)
