Analysis of the complete genomic sequences of two virus subpopulations of the Australian infectious bronchitis virus vaccine VicS 2015-04-01 .txt text/plain 5201 250 56 Compared with VicS-v, the more attenuated VicS-del strain had two non-synonymous changes in the non-structural protein 6 (nsp6), a transmembrane (TM) domain that may participate in autocatalytic release of the 3-chymotrypsin-like protease, a polymorphic difference at the end of the S2 gene, which coincided with the body transcription-regulating sequence (B-TRS) of mRNA 3 and a truncated open reading frame for a peptide encoded by gene 4 (4b). Phylogenetic analysis of the whole genome showed that VicS-v and VicS-del did not cluster with strains from other countries, supporting the hypothesis that Australian IBV strains have been evolving independently for some time, and analyses of individual polymerase peptide and S glycoprotein genes suggested a distant common ancestor with no recent recombination. For VicSdel, the readings were mapped to the genome of VicS-v and the previously determined sequence of the structural protein gene region of VicS-del (GAN JN983807). ./cache/cord-353310-19kzb6ag.txt ./txt/cord-353310-19kzb6ag.txt
