Cooperative binding to nucleic acids by barley yellow mosaic bymovirus coat protein and characterization of a nucleic acid-binding domain.
The capacity of several coat protein (CP) mutants of a German isolate of barley yellow mosaic bymovirus (BaYMV) to bind of nucleic acids was studied in vitro. Recombinant CP, produced by overexpression in Escherichia coli, was purified from inclusion bodies and subsequently renatured. Binding to single-stranded (ss) RNA and ssDNA oligonucleotides was found to be cooperative and sequence non-spe...
متن کامل35S promoter-driven cDNAs of barley mild mosaic virus RNA1 and RNA2 are infectious on barley plants.
Full-length cDNAs of barley mild mosaic bymovirus RNA1 and RNA2 were cloned downstream of a modified cauliflower mosaic virus 35S promoter with double enhancer. Mechanical inoculation of barley seedlings with a mixture of both cDNAs resulted in systemic mosaic symptoms, typical of barley mild mosaic virus infection. The presence of both RNA species and their gene products in the systemically in...
متن کاملComparison of barley stripe mosaic virus strains.
BSMV (barley stripe mosaic virus) particles were obtained in a pure state from infected host plant tissues of Hordeum vulgare. The three genomic parities (alpha, beta and gamma) were amplified by PCR using specific primers for each particle; each was cloned. Partial sequence of the alpha, beta and gamma segments was determined for the Egyptian isolate of barley stripe mosaic virus (BSMV AE1). A...
متن کاملClassical and next generation sequencing approaches unravel Bymovirus diversity in barley crops in France
Despite the generalized use of cultivars carrying the rym4 resistance gene, the impact of viral mosaic diseases on winter barleys increased in recent years in France. This change could reflect i) an increased prevalence of the rym4 resistance-breaking pathotype of Barley yellow mosaic virus Y (BaYMV-2), ii) the emergence of rym4 resistance-breaking pathotypes of Barley mild mosaic virus (BaMMV)...
متن کاملNeuropsychological characteristics of mild cognitive impairment subgroups.
OBJECTIVE To describe the neuropsychological characteristics of mild cognitive impairment (MCI) subgroups identified in the Cardiovascular Health Study (CHS) cognition study. METHODS MCI was classified as MCI-amnestic type (MCI-AT): patients with documented memory deficits but otherwise normal cognitive function; and MCI-multiple cognitive deficits type (MCI-MCDT): impairment of at least one ...
