| coat protein sequence comparisons of three medican isolates of papaya ringspot virus with other geographical isolates reveal a close relationship to american and australian isolates. | the coat protein gene of the papaya ringspot virus was cloned and sequenced in three mexican isolates (two from veracruz, and one from chiapas). the sequences of these viral isolates were compared to those of eleven isolates from other parts of the world. they had higher similarity to isolates from australia and the united states than to asian isolates. a region of about one hundred nucleotides neighboring the putative aphid transmission triplet of the coat protein, contained repeats of an ek (g ... | 2000 | 10893161 |
| molecular characterization of a severe isolate of papaya ringspot virus in mexico and its relationship with other isolates. | the virus most often reported in papaya (carica papaya l.) is papaya ringspot (prsv). the aim of this work was the molecular genomic characterization of a mexican severe isolate of prsv-p "mex-vrpo" (isolate from the state of veracruz in paso de ovejas) as well as its comparison with other isolates from other world regions. the linear, assembled, single-strand positive sense rna genome of prsv-p mex-vrpo was 10320 nt in length (excluding the poly(a) tail) and contained a single large predicted o ... | 2007 | 17082995 |
