tomato is one of the most important vegetables in iran and throughout the world with crop loss caused by several viruses. this survey was carried out to detect the viruses causing mosaic symptoms on tomato in yazd city (iran). a total of 451 samples of tomato leaves showing mosaic symptoms were collected from fields and greenhouses during 2012-2013 growing season. collected samples were analyze...

In this study, it was aimed to reveal some viruses that are a problem in tomato production areas the Ereğli district of Konya, where is common. For reason, 2019 season, leaf samples were taken from 160 plants showing symptoms similar virus disease such as mosaic, deformations, yellowing, blight on leaves and stunted plants. Possible infections Cucumber mosaic (CMV), Tomato spotted-wilt (TSWV) (...

Cucumber Mosaic Virus (CMV) is a plant infecting tripartite positive-strand RNA virus. In addition to three genomic and two known subgenomic RNAs, CMV strains of subgroup II (e.g. Q-CMV), but not subgroup I (e.g. Fny-CMV), produce and package a redundant RNA5 encompassing the 3' 304-307 nucleotides of RNAs 2 and 3. The mechanism regulating RNA5 production and its role in CMV life cycle is unkno...

Pepper lines L57 and L113 and cv.Pico are inoculated by 1, 5, 10, 25, 75 μg/ml cucumber mosaic virus (CMV) in inoculum. Both lines are resistant to the virus and cv.Pico is used as a susceptible control. The lines respond with the development of chlorotic (L57) and necrotic (L113) spots on the inoculated leaf. The virus is established only in the inoculated leaves and their petioles of the resi...

Tobacco is widely planted across the world especially in China, which means that a large amount of tobacco waste needs to be treated. This study investigated the biogas fermentation of tobacco stalks co-digested with different biomass feedstocks and the inactivation of Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV) by anaerobic digestion. Results showed that the maximum methane yield o...

Replication of viral RNA genomes requires the specific interaction between the replicase and the RNA template. Members of the Bromovirus and Cucumovirus genera have a tRNA-like structure at the 3' end of their genomic RNAs that interacts with the replicase and is required for minus-strand synthesis. In Brome mosaic virus (BMV), a stem-loop structure named C (SLC) is present within the tRNA-like...

Aim. Screening of vegetable crops for mixed viral infections caused by 8 viruses, and evaluation relative share different combinations pathogens using serological methods plant virus diagnostics. Methods. Double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was performed detection antigens. Results. For this study, the samples from plants with virus-like symptoms were collecte...

cucumber mosaic virus (cmv) belongs to the genus cucumovirus in the family bromoviridae. althaea officinalis, commonly known as hollyhocks in the family malvaceae, is an annual plant whose fruit, flower and root are used as medicinal products. in this study, five samples of hollyhocks leaves with viral symptoms were collected and cmv was detected using das-elisa from the samples. ta-alth isolat...

Background: Cucumber mosaic virus (CMV) is one of the most important viruses infecting vegetables in the fields throughout the world. Transmission efficiency of CMV could depend on the variability of virus strain but also aphid vector species and/or clones. Materials and Methods: By sequence analysis, the coat protein gene of CMV strains from different regions revealed that the CMV isolates use...
