Radish Enation Mosaic Virus

Genetic Variability of the Czech Pea enation mosaic virus Isolates

Šafářová D., Navrátil M. (2014): Genetic variability of the Czech Pea enation mosaic virus isolates. Czech J. Genet. Plant Breed., 50: 100–104. The Pea enation mosaic virus is an example of symbiogenesis of taxonomically unrelated PEMV-1 and PEMV-2 viruses. Partial RNA sequences, PEMV-1 coat protein, PEMV-2 movement protein gene and satellite RNA from seventeen isolates were compared with the a...

Multiple Cis-acting elements modulate programmed -1 ribosomal frameshifting in Pea enation mosaic virus

Programmed -1 ribosomal frameshifting (-1 PRF) is used by many positive-strand RNA viruses for translation of required products. Despite extensive studies, it remains unresolved how cis-elements just downstream of the recoding site promote a precise level of frameshifting. The Umbravirus Pea enation mosaic virus RNA2 expresses its RNA polymerase by -1 PRF of the 5'-proximal ORF (p33). Three hai...

Role of Pea Enation Mosaic Virus Coat Protein in the Host Plant and Aphid Vector

Understanding the molecular mechanisms involved in plant virus-vector interactions is essential for the development of effective control measures for aphid-vectored epidemic plant diseases. The coat proteins (CP) are the main component of the viral capsids, and they are implicated in practically every stage of the viral infection cycle. Pea enation mosaic virus 1 (PEMV1, Enamovirus, Luteovirida...

Conditional Facilitation of an Aphid Vector, Acyrthosiphon pisum, by the Plant Pathogen, Pea Enation Mosaic Virus

Plant pathogens can induce symptoms that affect the performance of insect herbivores utilizing the same host plant. Previous studies examining the effects of infection of tic bean, Vicia faba L. (Fabales: Fabaceae), by pea enation mosaic virus (PEMV), an important disease of legume crops, indicated there were no changes in the growth and reproductive rate of its primary vector the pea aphid, Ac...
