| molecular characterisation of potexviruses isolated from three different genera in the family cactaceae. | the genome properties of three potexviruses which previously had been isolated from different genera in the family cactaceae and had been found to be only distantly related serologically have been studied. the sequence of the 3040 3' terminal nucleotides of the genomic rna of isolate k11 from schlumbergera bridgesii and the complete rna sequences of isolates b1 and cc10 from zygocactus sp. and opuntia sp., respectively, were determined. starting sequences were obtained by means of immunocapture ... | 2004 | 15098106 |
| zygocactus virus x-based expression vectors and formation of rod-shaped virus-like particles in plants by the expressed coat proteins of beet necrotic yellow vein virus and soil-borne cereal mosaic virus. | expression vectors were constructed from 35s promoter-containing full-length cdna clones of zygocactus virus x (zvx). the expression of foreign genes was driven by the zvx coat protein (cp) subgenomic promoter. it was successful only when the variable region downstream of the conserved putative promoter region gsttaagtt(x(12-13))gaa was retained. most of the zvx cp gene, except for a short 3' part, was replaced by the corresponding sequence of the related schlumbergera virus x (svx) and its cp s ... | 2006 | 16432032 |
| genome assembly of schlumbergera virus x infecting prickly pear (opuntia cochenillifera) in brazil. | potexviruses frequently infect plants from the family cactaceae. we report the complete genome sequence of a new schlumbergera virus x (schvx) isolate. the genome has 6,615 nucleotides and shares 94% nucleotide identity with schvx-k11 from schlumbergera. this is the first sequence of an isolate of schvx from the genus opuntia. | 2015 | 25792054 |
