“…It is interesting to note that sequences of nucleotide at termini of 11 genome segments have been found to be identical between RVD as well as RVA (Trojnar et al 2010). In case of mammalian RVA, segment 5 was found to migrate closer to 6, whereas in AvRVs, segments 7, 8 and 9 were found to migrate as a tight triplet (Wani et al 2003).…”

“…Reassortment is known to occur within mammalian and avian RVA (Ward et al, 1990;Schumann et al, 2009). However, although interspecies transmission of mammalian RVA to birds and of avian RVA to mammals can occur (Brussow et al, 1992a(Brussow et al, , 1992bMori et al, 2001;Wani et al, 2003;Asano et al, 2011), mammalian and avian RVA are believed to have diverged along with their hosts and to have evolved independently without reassortment (Ito et al, 2001;Trojnar et al, 2009). Reassortment may be suppressed not only by the incompatibility of packaging signals but also by incompatibility in the functions of proteins encoded by genomic segments (Hutchinson et al, 2010;McDonald and Patton, 2011).…”

A possible packaging signal in the rotavirus genome

Group A rotavirus (RVA), an etiological agent of gastroenteritis in young mammals and birds, possesses a genome of 11 double-stranded RNA segments. Although it is believed that the RVA virion contains one copy of each genomic segment and that the positive-strand RNA (+RNA) is incorporated into the core shell, the packaging mechanisms of RVA are not well understood. Here, packaging signals of RVA were searched for by analyzing genomic sequences of mammalian and avian RVA, which are considered to have evolved independently without reassortment. Assuming that packaging is mediated by direct interaction between +RNA segments via base-pairing, co-evolving complementary nucleotide sites were identified within and between genomic segments. There were two pairs of co-evolving complementary sites within the segment encoding VP7 (the VP7 segment) and one pair between the NSP2 and NSP3 segments. In the VP7 segment, the co-evolving complementary sites appeared to form stem structures in both mammalian and avian RVA, supporting their functionality. In contrast, coevolving complementary sites between the NSP2 and NSP3 segments tended to be free from base-pairings and constituted loop structures, at least in avian RVA, suggesting that they are involved in a specific interaction between these segments as a packaging signal.

“…Based on above results, the genotypes of AvRV-2 strain were related with those of chicken strains and it suggested that the reassortment between AvRV-2 strain and other species did not yet occurred. Reassortment between mammalian and avian rotaviruses were reported (Wani et al, 2003). Reassortment among bovine, porcine and human rotavirus strains was also reported in Korea (Park et al, 2011).…”

An avian rotavirus (AvRV-2) was isolated from feces of broilers suffering from acute gastroenteritis in 2011. It was the first avian rotavirus isolated in Korea. To investigate the molecular characteristics of AvRV-2, the VP4, VP6, VP7 and NSP4 gene nucleotide sequences were determined and compared with those of rotavirus strains available in the GenBank database. The phylogenetic tree of VP7 gene showed that AvRV-2 had a high degree of nucleotide sequence homology (93.4% to 94.7%) with those of rotaviruses belonging to genotype G19 cluster. The phylogenetic tree of the VP4 gene revealed a high degree of nucleotide sequence homology (95.8% to 95.9%) with genotype P[30] rotaviruses isolated from chickens. The VP6 and NSP4 gene nucleotide sequences showed the highest identities with those of avian strains with 95.3% to 96.4% and 90.3% to 92.2%, respectively. Genetic characterization of the VP4, VP6, VP7 and NSP4 showed that AvRV-2 strain was most closely related to chicken rotavirus strains from Germany and Japan. Comparative nucleotide sequences and phylogenetic analysis indicated that avian rotavirus isolated from broilers belonged to genotype G19P [30] and it was the first report on avian rotavirus infection in Korea.
