Cell Death Is Not Sufficient for the Restriction of Potato Virus Y Spread in Hypersensitive Response-Conferred Resistance in Potato
Hypersensitive response (HR)-conferred resistance to viral infection restricts the virus spread and is accompanied by the induction of cell death, manifested as the formation of necrotic lesions. While it is known that salicylic acid is the key component in the orchestration of the events restricting viral spread in HR, the exact function of the cell death in resistance is still unknown. We sho...
متن کاملHost-dependent requirement for the Potato leafroll virus 17-kda protein in virus movement.
The requirement for the 17-kDa protein (P17) of Potato leafroll virus (PLRV) in virus movement was investigated in four plant species: potato (Solanum tuberosum), Physalis floridana, Nicotiana benthamiana, and N. clevelandii. Two PLRV P17 mutants were characterized, one that does not translate the P17 and another that expresses a P17 missing the first four amino acids. The P17 mutants were able...
متن کاملEvolutionary features of 8K (KDa) silencing suppressor protein of Potato mop-top virus
The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...
متن کاملAnalysis of the DNase I-hypersensitive site of a developmentally regulated 25-kDa protein gene of Sarcophaga peregrina.
Change in chromatin structure of a developmentally regulated gene of Sarcophaga peregrina (flesh fly) during development was investigated. This gene (25-kDa protein gene) was specifically activated in the fat body, but not the hemocytes of larvae in the middle of the third instar. The mRNA level in the fat body decreased thereafter, reaching one-fifth of the maximum level in the late third inst...
متن کاملPlant Translation Elongation Factor 1Bβ Facilitates Potato Virus X (PVX) Infection and Interacts with PVX Triple Gene Block Protein 1
The eukaryotic translation elongation factor 1 (eEF1) has two components: the G-protein eEF1A and the nucleotide exchange factor eEF1B. In plants, eEF1B is itself composed of a structural protein (eEF1Bγ) and two nucleotide exchange subunits (eEF1Bα and eEF1Bβ). To test the effects of elongation factors on virus infection, we isolated eEF1A and eEF1B genes from pepper (Capsicum annuum) and supp...
