| three distinct begomoviruses associated with soybean in central brazil. | we report the complete nucleotide sequences of geminiviruses of the genus begomovirus infecting soybean (glycine max) in central brazil. samples obtained from soybean plants collected at santo antonio de goiás, goiás state, showing typical symptoms of viral infection, were analyzed. infection was confirmed by pcr-based amplification of a dna-a fragment with universal begomovirus primers. total dna from infected plants was then subjected to rolling-circle amplification (rca), and 2.6-kb molecules ... | 2009 | 19636495 |
| further evidence reveals that okra mottle virus arose from a double recombination event. | as a result of surveys of okra begomoviruses (genus begomovirus, family geminiviridae) conducted over the last five years in central brazil, we report the complete genome sequence of an isolate of okra mottle virus (omov). the dna-a and dna-b components were 2660 and 2653 nucleotides (nt) long, respectively, and they were most closely related to the dna-a (~99 % nt identity) and dna-b (~98 % nt identity) components of an omov isolate from a soybean plant. a phylogenetic tree was generated based ... | 2013 | 22941555 |
