“…It appears to heavily contribute to begomovirus genetic diversity, increasing the evolutionary potential and local adaptation of strains (Berrie et al, 2001;Graham et al, 2010;Harrison & Robinson, 1999;Monci et al, 2002;Padidam et al, 1999). There is ample opportunity for recombination because multiple begomovirus species are often found co-infecting the same plant (Davino et al, 2009;García-Andrés et al, 2006;Harrison et al, 1997;Pita et al, 2001;Ribeiro et al, 2003;Sanz et al, 2000;Torres-Pacheco et al, 1996), and more than one virus can simultaneously replicate in the same nucleus (Morilla et al, 2004). Additionally, the high recombination frequency observed for begomoviruses may be explained by a theoretical recombination-dependent replication mechanism (RDR) (Jeske et al, 2001), in addition to the welldocumented rolling circle replication (RCR) (Saunders et al, 2001).…”
