Variability of Bean yellow mosaic virus isolates in the Czech Republic.

An appropriate method to determine the interaction type of Cucumber mosaic virus (CMV) and Bean yellow mosaic virus (BYMV)

The occurrence of viral co-infection is a common phenomenon in cultivated and native plant species and can alter the dynamics of virus infection. In this study, disease progress was examined in single and mixed infections of Cucumber mosaic virus (CMV) and Bean yellow mosaic virus (BYMV) by measuring the rate of symptom development, disease severity and area under disease progress curve on infe...

Degenerate Primers Facilitate the Detection and Identification of Potyviruses From the Northwest Region of Iran

Background: Potyviruses are accounted for 40% of viral diseases of various crops including vegetables and legumes. Potyviruses can be transmitted through plant sap, seeds and many aphid species. Due to ease of spread of these viruses detection of such viruses are crucial as to the control of the incited diseases. Objectives: This study compared the efficiencies of two couples of primers in the...

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...

Silver nanoparticles synthesis mediated by new isolates of Bacillus spp., nanoparticle characterization and their activity against Bean Yellow Mosaic Virus and human pathogens

Extracellular agents produced by newly isolated bacterial strains were able to catalyze the synthesis of silver nanoparticles (AgNPs). The most effective isolates were identified as Bacillus pumilus, B. persicus, and Bacillus licheniformis using molecular identification. DLS analysis revealed that the AgNPs synthesized by the above strains were in the size range of 77-92 nm. TEM observations sh...
