We also determined the full genome sequences of 19 dicot-infecting mastrevirus isolates recovered from symptomatic plant samples collected in Australia between 2002 and 2011. This dataset was analysed together with all previously described monocot- and dicot-infecting mastreviruses and through this we identified six divergent strains of CpCDV. check details Despite 10 years of effort sampling dicotyledonous plant species and using methods such as rolling circle amplification and next generations sequencing to identify and recover circular ssDNA viruses from infected plant material, the only regions of the world where dicot infecting mastreviruses have been conclusively identified are the Middle East, East Africa, Australia and South Africa. However, fragments of a dicot-infecting mastrevirus-like genome have been discovered through deep sequencing of small RNAs extracted from Peruvian sweet-potatoes (Kreuze et al., 2009) suggesting that the currently known distribution of these viruses is almost definitely an under-estimation of their geographical range. It is nevertheless possible for us to determine which of the regions where these viruses have been sampled is nearest to their geographical origin. Our results support the prevailing Pembrolizumab concentration notion that the degree of dicot-infecting mastrevirus diversity outside of Australia is lower than that within Australia and that the dicot-infecting viruses discovered in the former regions most likely originated either in or near Australia. Forty-nine dicot-infecting mastrevirus genomes (Table 1) were recovered from chickpea (n=40), lentil (n=4), faba bean (n=2), field pea (n=2) and bean (n=1). These 49 viral genomes and 48 others available セレックバイオテック株式会社 in GenBank were assembled into a single dataset and genome-wide pairwise identities between every possible pair of sequences were calculated (1 minus p-distance calculated with pairwise deletion of gaps; Fig. 1A) so as to assess the over-all genetic diversity of these viruses. Based on the recommendations of Muhire et al. (2013) 18 of the 19 Australian dicot-infecting mastrevirus genomes could be assigned to previously named species and strain groupings; TYDV (1/19), CpCAV (7/19), CpCV-A (3/19), CpCV-B (1/19), and CpCV-E (6/19). The one exceptional Australian dicot-infecting isolate was clearly a member of the species CpCV but was
