“…On the other hand, DNA-U3 was notable for having the highest diversity of all BBTV components (Hyder 2009), but the DNA-U3 of Sumatra isolates had high identity (Table S3). This is similar to the results for the Pakistan and Tonga populations (Hyder et al 2011;Stainton et al 2012). Since the nucleotide sequence of DNA-U3 had not been determined in Indonesia isolates until now, our data will be especially useful for the investigation of BBTV in Indonesia.…”

“…Th ese results confi rmed the sequence and phylogenetic analyses of BBTV DNA-R, which supported the geographical structuring of BBTV isolates (Hu et al, 2007;Yu et al, 2012). However, DNA-U3 was more variable (22.2%) than other components of BBTV (2.8-14%), which was caused by diff erent evolutionary pressures on each component and/ or DNA component recombination in the genome of BBTV isolates (Hu et al, 2007;Hyder et al, 2011). Noticeably, DNA-U3 in this study was detected the absence of an additional TATA box or a small ORF, this fi nding is opposite to previous reports (Yu et al, 2012), thereby emphasizing the additional components of DNA-U3.…”

Banana bunchy top virus (BBTV) (the genus Babuvirus, the family Nanoviridae) is a single-stranded circular DNA virus with a genome composed of six components designated as DNA-R, -U3, -S, -M, -C, and -N. This study analyzed the nucleotide identities of the DNA-R of 23 isolates from banana-producing provinces of China, including Guangdong, Hainan, Guangxi, and Yunnan. Results showed that the nucleotide identity of DNA-R was 72.3-100%. Phylogenetic analysis indicated that these BBTV isolates were clustered in different subgroups within the Asian group (AG). Sequence analysis of the five other components (DNA -U3, -S, -M, -C, and -N) of the five isolates from China confirmed the results established for DNA-R of these BBTV isolates. This study suggested that the variation of DNA-R from Chinese BBTV isolates was considerably higher than the variation of other AG isolates, but their genetic diversity was low.

“…It is probable that homologous recombination plays an important role in the production and adaptation of genome component reassortants. Given that DNA-A will rapidly and efficiently rescue a replication incompetent DNA-B component via homologous recombination [46,47,120,121], it is possible (if not probable) that the geminiviral DNA-A and the nanoviral DNA-R components maintain their replicational control over their dependent components by frequently updating the common regions of the dependent components by homologous recombination [46,47,120,121].…”

Although single stranded (ss) DNA viruses that infect humans and their domesticated animals do not generally cause major diseases, the arthropod borne ssDNA viruses of plants do, and as a result seriously constrain food production in most temperate regions of the world. Besides the well known plant and animal-infecting ssDNA viruses, it has recently become apparent through metagenomic surveys of ssDNA molecules that there also exist large numbers of other diverse ssDNA viruses within almost all terrestrial and aquatic environments. The host ranges of these viruses probably span the tree of life and they are likely to be important components of global ecosystems. Various lines of evidence suggest that a pivotal evolutionary process during the generation of this global ssDNA virus diversity has probably been genetic recombination. High rates of homologous recombination, non-homologous recombination and genome component reassortment are known to occur within and between various different ssDNA virus species and we look here at the various roles that these different types of recombination may play, both in the day-to-day biology, and in the longer term evolution, of these viruses. We specifically focus on the ecological, biochemical and selective factors underlying patterns of genetic exchange detectable amongst the ssDNA viruses and discuss how these should all be considered when assessing the adaptive value of recombination during ssDNA virus evolution.
