Adaptive evolution by recombination is not associated with increased mutation rates in Maize streak virus

Author: Monjane, Aderito ; Pande, Daniel ; Lakay, Francisco ; Shepherd, Dionne ; van der Walt, Eric ; Lefeuvre, Pierre ; Lett, Jean-Michel ; Varsani, Arvind ; Rybicki, Edward ; Martin, Darren Date: 2012 BACKGROUND: Single-stranded (ss) DNA viruses in the family Geminiviridae are proving to be very useful in real-time evolution studies. The high mutation rate of geminiviruses and other ssDNA viruses is somewhat mysterious in that their DNA ... Read more c b
Comparative analysis of Panicum streak virus and Maize streak virus diversity, recombination patterns and phylogeography

Author: Varsani, Arvind ; Monjane, Aderito ; Donaldson, Lara ; Oluwafemi, Sunday ; Zinga, Innocent ; Komba, Ephrem ; Plakoutene, Didier ; Mandakombo, Noella ; Mboukoulida, Joseph ; Semballa, Silla ; Briddon, Rob ; Markham, Peter ; Lett, Jean-Michel ; Lefeuvre, Pierre ; Ry Date: 2009 BACKGROUND: Panicum streak virus (PanSV; Family Geminiviridae; Genus Mastrevirus) is a close relative of Maize streak virus (MSV), the most serious viral threat to maize production in Africa. PanSV and MSV have the same leafhopper vector ... Read more c b
Experimental evidence indicating that mastreviruses probably did not co-diverge with their hosts

Author: Harkins, Gordon ; Delport, Wayne ; Duffy, Siobain ; Wood, Natasha ; Monjane, Aderito ; Owor, Betty ; Donaldson, Lara ; Saumtally, Salem ; Triton, Guy ; Briddon, Rob ; Shepherd, Dionne ; Rybicki, Edward ; Martin, Darren ; Varsani, Arvind Date: 2009 BACKGROUND:Despite the demonstration that geminiviruses, like many other single stranded DNA viruses, are evolving at rates similar to those of RNA viruses, a recent study has suggested that grass-infecting species in the genus Mastrevirus ...

A highly divergent South African geminivirus species illuminates the ancient evolutionary history of this family

Author: Varsani, Arvind ; Shepherd, Dionne ; Dent, Kyle ; Monjane, Aderito ; Rybicki, Edward ; Martin, Darren Date: 2009 BACKGROUND:We have characterised a new highly divergent geminivirus species, Eragrostis curvula streak virus (ECSV), found infecting a hardy perennial South African wild grass. ECSV represents a new genus-level geminivirus lineage, and has a ... Read more c b
Recombination hotspots and host susceptibility modulate the adaptive value of recombination during maize streak virus evolution

Author: Monjane, Aderito ; van der Walt, Eric ; Varsani, Arvind ; Rybicki, Edward ; Martin, Darren Date: 2011 BACKGROUND:Maize streak virus -strain A (MSV-A; Genus Mastrevirus, Family Geminiviridae), the maize-adapted strain of MSV that causes maize streak disease throughout sub-Saharan Africa, probably arose between 100 and 200 years ago via homologous ...
