Cucumber mosaic virus (CMV) has a worldwide distribution and the widest host range of any known plant virus. From 2000 to 2012, epidemics of CMV severely affected the production of snap bean (Phaseulos vulgaris L.) in the Midwest and Northeastern United States. Virus diversity leading to emergence of new strains is often considered a significant factor in virus epidemics. In addition to epidemi...

Weeds may contribute to the spread of plant virus epidemics by acting as reservoirs viruses or/and their vectors. The aim this research was study prevalence five viral pathogens in weeds fields solanaceous crops six provinces Poland differing with soil and climate conditions. Most sampled sites were associated tobacco production. total number 157 samples 600 subjected DAS-ELISA detection tomato...

Gerbera spp., which is in the Asteraceae family, most widely cultivated cut flower ornamental plant Türkiye after carnation. Approximately 74% of Türkiye's production met from Antalya province. Virus diseases are a problem cultivation as they significantly reduce yield and quality. In this study, was carried out to detect some virus seen areas province, surveys were commercial 2021-2022 season....

Positive-strand RNA viruses are known to rearrange the endomembrane network to make it more conducive for replication, maturation, or egress. Our previous transmission electron microscopic (TEM) analysis showed that ectopic expression of wild-type (wt) capsid protein (CP) of Brome mosaic virus (BMV) has an intrinsic property of modifying the endoplasmic reticulum (ER) to induce vesicles similar...

BACKGROUND Argonaute (AGO) proteins bind to small-interfering (si)RNAs and micro (mi)RNAs to target RNA silencing against viruses, transgenes and in regulation of mRNAs. Plants encode multiple AGO proteins but, in Arabidopsis, only AGO1 is known to have an antiviral role. METHODOLOGY/PRINCIPAL FINDINGS To uncover the roles of specific AGOs in limiting virus accumulation we inoculated turnip c...

Many plant host factors are known to interact with viral proteins during pathogenesis, but how a plant virus induces a specific disease symptom still needs further research. A lily strain of Cucumber mosaic virus (CMV-HL) can induce discrete necrotic spots on infected Arabidopsis (Arabidopsis thaliana) plants; other CMV strains can induce similar spots, but they are not as distinct as those ind...

Population diversity was examined in individual and natural mixed infections of Cowpea chlorotic mottle virus (CCMV) and Cucumber mosaic virus (CMV) isolates in two systemic hosts, cowpea and Nicotiana benthamiana. Isolates of CCMV and CMV obtained from a cowpea field in Arkansas were separated biologically in cowpea and tobacco plants, respectively. After separation, individual and mixed cultu...
