Host Plants Shape the Codon Usage Pattern of Turnip Mosaic Virus

Abstract: Turnip mosaic virus (TuMV), an important pathogen that causes mosaic diseases in vegetable crops worldwide, belongs to the genus Potyvirus of the family Potyviridae. Previously, the areas of genetic variation, population structure, timescale, and migration of TuMV have been well studied. However, the codon usage pattern and host adaptation analysis of TuMV is unclear. Here, compositional bias and codon usage of TuMV were performed using 184 non-recombinant sequences. We found a relatively stable change existed… Show more

“…Moreover, our study contributes to understanding the mutation pressures shaping codon usage in ToBRFV genes. We found a preference for A/G in TuMV protein-coding regions, indicative of mutation pressures (Qin et al, 2022). This insight underscores the dynamic nature of codon usage and its implications for viral evolution and adaptation.…”

“…The results of this index were in line with the CAI index. A low RCDI may suggest a strong adaptation to the host [47,48], while in the CAI index, this phenomenon is vice versa. The field of plant virus phylogenetics has advanced significantly due to the exponential increase in available genome sequence data and the development of dedicated bioinformatics tools for analyzing these data.…”

“…A slope approaching 1 suggests that codon usage is primarily influenced by mutation pressure. Conversely, a slope closer to zero signifies that natural selection plays a more prominent role in shaping the bias of codon usage [34].…”
