| a novel begomovirus isolated from sida contains putative cis- and trans-acting replication specificity determinants that have evolved independently in several geographical lineages. | a novel begomovirus isolated from a sida rhombifolia plant collected in sinaloa, mexico, was characterized. the genomic components of sida mosaic sinaloa virus (simsinv) shared highest sequence identity with dna-a and dna-b components of chino del tomate virus (cdtv), suggesting a vertical evolutionary relationship between these viruses. however, recombination analysis indicated that a short segment of simsinv dna-a encompassing the plus-strand replication origin and the 5´-proximal 43 codons of ... | 2014 | 24737005 |
| complete nucleotide sequences of a new bipartite begomovirus from malvastrum sp. plants with bright yellow mosaic symptoms in south texas. | two isolates of a novel bipartite begomovirus, tentatively named malvastrum bright yellow mosaic virus (mabymv), were molecularly characterized from naturally infected plants of the genus malvastrum showing bright yellow mosaic disease symptoms in south texas. six complete dna-a and five dna-b genome sequences of mabymv obtained from the isolates ranged in length from 2,608 to 2,609 nucleotides (nt) and 2,578 to 2,605 nt, respectively. both genome segments shared a 178- to 180-nt common region. ... | 2016 | 27016928 |
