Vector transmission of parsley yellow leaf curl virus by the leafhopper Austroagallia sinuata.

Parsley yellow leaf curl virus (PYLCV) is a new member of the family Geminiviridae that has not yet been assigned to an established genus due to limited information about its biological properties. In this study, the ability of Austroagallia leafhoppers, which are commonly found on vegetable farms in Kerman province (Iran), to transmit this virus was studied. After a two-day acquisition access period, Austroagallia sp.

Metatranscriptome analysis of symptomatic bitter apple plants revealed mixed viral infections with a putative novel polerovirus.

Background: Next-generation Sequencing (NGS) combined with bioinformatic analyses constitutes a powerful approach for identifying and characterizing previously unknown viral genomes. In this study, leaf samples from bitter apple plants (Citrullus colocynthis (L.) Schrad) exhibiting symptoms such as dwarfing, leaf crinkling, and chlorosis were collected from the southern part of Kerman province, Iran.

Identification of the wild and cultivated hosts of wheat dwarf virus and oat dwarf virus in Iran.

In the last decade two mastreviruses, (WDV) and (ODV) have been reported from cereal farms in Iran. In a survey, wild and cultivated hosts of these mastreviruses were studied during 2015 to 2017. Symptomatic small grain cereal samples and weed species were collected and assayed for WDV and/or ODV infection by PCR.

Novel nanovirus and associated alphasatellites identified in milk vetch plants with chlorotic dwarf disease in Iran.

Members of the family Nanoviridae are multi-component single-stranded DNA viruses that infect a variety of plant species. Using a combination of conventional PCR and high throughput sequencing-based approach, we identified a novel nanovirus infecting two symptomatic milk vetch plants (Astragalus myriacanthus Boiss.; family Fabaceae) showing marginal leaf chlorosis, little leaves and dwarfing in Iran.

Identification of a new turncurtovirus in the leafhopper Circulifer haematoceps and the host plant species Sesamum indicum.

Turncurtoviruses (family: Geminiviridae; genus: Turncurtovirus) appear to have a high degree of genetic variation in Iran. Leafhoppers of the species Circulifer haematoceps (Mulsant and Rey, 1855) (family: Cicadellidae) were collected in 2014 from three geographical regions in south-eastern Iran (Orzoeyeh, Jiroft and Sirjan; Kerman province) and screened for the presence of turncurtoviruses using a combination of PCR and rolling circle amplification (RCA) methods. Eleven genomes of turncurtovirus were recovered and sequenced.
