| 520 | _aSugarcane mosaic virus (SCMV), a member of the genus Potyvirus in the family Potyviridae, is an important pathogen that causes mosaic diseases in maize, sugarcane, canna and other graminaceous species worldwide. Previously, several reports have showed the genetic variation and population structure of SCMV. However, the evolutionary dynamics, synonymous codon usage pattern and adaptive evolution of the virus is unclear. In this study, we performed comprehensive analyses of phylodynamics, composition bias and codon usage of SCMV using 108 complete genomic sequences. Our phylogenetic analysis found six host- and geographically confined phylogenetic lineages within the SCMV non-recombinant isolates. We found a relatively stable and conserved genomic composition with a lower codon usage choice in the SCMV protein coding sequences. Mutation pressure and natural selection have shaped the codon usage patterns of the SCMV protein coding sequences with natural selection being the dominant factor. The codon adaptation index (CAI), relative codon deoptimization index (RCDI) and similarity index (SiD) analyses revealed a stronger correlation between SCMV and maize than between SCMV and sugarcane or canna. Our study is the first to evaluate the codon usage pattern of SCMV based on complete sequences and may provide a better understanding of the origin of SCMV and its evolutionary patterns for future research. | ||
