Effect of Artificial dsRNA on Infection of Pea Plants by Pea seed-borne mosaic virus
Šafářová D., Brázda P., Navrátil M. (2014): Effect of artificial dsRNA on infection of pea plants by Pea seedborne mosaic virus. Czech J. Genet. Plant Breed., 50: 105–108. The effect of direct application of artificial dsRNA molecules derived from the viral coat protein gene and the possibility of RNA interference induction leading to protection against Pea seed borne mosaic virus (PSbMV) have ...
متن کاملP1 peptidase of Pea seed-borne mosaic virus contains non- canonical C2H2 zinc finger and may act in a truncated form
Background: Pea seed-borne mosaic virus (PSbMV) is a member of the genus Potyvirus that can be transmitted by seeds, causing serious losses in legume crop yields. Its genome consists of 3 peptidases-P1, HC-Pro, and NIa. Interestingly, only the P1 peptidase, localized on the N-terminal portion of the viral polyprotein, still remains without any concrete function on influencing viral infections. ...
متن کاملAnalysis of the accumulation of Pea enation mosaic virus genomes in seed tissues and lack of evidence for seed transmission in pea (Pisum sativum).
Pea enation mosaic virus (PEMV) is an important virus disease of pea. International movement of commercial pea cultivars and germplasm can be problematic due to uncertainty about seed transmission of the viruses responsible for the disease. Whether PEMV is seedborne was assessed by collecting developing seed from infected plants and determining the relative concentrations of the PEMV-1 and PEMV...
متن کاملStructure-Based Mutational Analysis of eIF4E in Relation to sbm1 Resistance to Pea Seed-Borne Mosaic Virus in Pea
BACKGROUND Pea encodes eukaryotic translation initiation factor eIF4E (eIF4E(S)), which supports the multiplication of Pea seed-borne mosaic virus (PSbMV). In common with hosts for other potyviruses, some pea lines contain a recessive allele (sbm1) encoding a mutant eIF4E (eIF4E(R)) that fails to interact functionally with the PSbMV avirulence protein, VPg, giving genetic resistance to infectio...
متن کاملCorrection: Narrow Bottlenecks Affect Pea Seedborne Mosaic Virus Populations during Vertical Seed Transmission but not during Leaf Colonization
The effective size of populations (Ne) determines whether selection or genetic drift is the predominant force shaping their genetic structure and evolution. Populations having high Ne adapt faster, as selection acts more intensely, than populations having low Ne, where random effects of genetic drift dominate. Estimating Ne for various steps of plant virus life cycle has been the focus of sever...
