Potato leafroll polerovirus (PLRV) genomic RNA acts as a polycistronic mRNA for the production of proteins P0, P1, and P2 translated from the 5'-proximal half of the genome. Within the P1 coding region we identified a 5-kDa replication-associated protein 1 (Rap1) essential for viral multiplication. An internal ribosome entry site (IRES) with unusual structure and location was identified that re...
Northern blot analysis of Solanum tuberosum infected with potato leafroll luteovirus revealed the 6 kb genomic RNA and a major 2.3 kb subgenomic RNA. The 5' end of the subgenomic RNA was located at nucleotide 3653 in an intergenic region located at the centre of the viral genome upstream of three open reading frames (ORFs). Transient expression in tobacco and potato protoplasts of the beta-gluc...
Grapevine leafroll disease (GLD) is one of the most important grapevine viral diseases affecting grapevines worldwide. The impact on vine health, crop yield, and quality is difficult to assess due to a high number of variables, but significant economic losses are consistently reported over the lifespan of a vineyard if intervention strategies are not implemented. Several viruses from the family...
Grapevine leafroll disease (GLRD) is one of the most important viral diseases grapevine worldwide. The aim this study was to investigate prevelance associated virus-1 (GLRaV-1), leafroll-associated virus-2 (GLRaV-2), virus-3 (GLRaV-3), virus 4 (GLRaV-4), and virus-9 (GLRaV-9) in Tokat province Turkey. In 2018, leaf samples one-year-old shoots plants, showing virus-like symptoms, were collected ...
A GroEL homolog with a molecular mass of 60 kDa, produced by the primary endosymbiotic bacterium (a Buchnera sp.) of Myzus persicae and released into the hemolymph, has previously been shown to be a key protein in the transmission of potato leafroll virus (PLRV). Like other luteoviruses and pea enation mosaic virus, PLRV readily binds to extracellular Buchnera GroEL, and in vivo interference in...
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 thei...
