| capulavirus and grablovirus: two new genera in the family geminiviridae. | geminiviruses are plant-infecting single-stranded dna viruses that occur in most parts of the world. currently, there are seven genera within the family geminiviridae (becurtovirus, begomovirus, curtovirus, eragrovirus, mastrevirus, topocuvirus and turncurtovirus). the rate of discovery of new geminiviruses has increased significantly over the last decade as a result of new molecular tools and approaches (rolling-circle amplification and deep sequencing) that allow for high-throughput workflows. ... | 2017 | 28213872 |
| molecular characterization and prevalence of two capulaviruses: alfalfa leaf curl virus from france and euphorbia caput-medusae latent virus from south africa. | little is known about the prevalence, diversity, evolutionary processes, genomic structures and population dynamics of viruses in the divergent geminivirus lineage known as the capulaviruses. we determined and analyzed full genome sequences of 13 euphorbia caput-medusae latent virus (ecmlv) and 26 alfalfa leaf curl virus (alcv) isolates, and partial genome sequences of 23 ecmlv and 37 alcv isolates. while ecmlv was asymptomatic in uncultivated southern african euphorbia caput-medusae, severe alf ... | 2016 | 27038709 |
| identification and characterisation of a highly divergent geminivirus: evolutionary and taxonomic implications. | during a large scale "non a priori" survey in 2010 of south african plant-infecting single stranded dna viruses, a highly divergent geminivirus genome was isolated from a wild spurge, euphorbia caput-medusae. in addition to being infectious in e. caput-medusae, the cloned viral genome was also infectious in tomato and nicotiana benthamiana. the virus, named euphorbia caput-medusae latent virus (ecmlv) due to the absence of infection symptoms displayed by its natural host, caused severe symptoms ... | 2013 | 23886668 |
