摘要
族群s of plant RNA 病毒es are highly polymorphic in infected plants, which may allow rapid within-host 演化. To understand tobacco etch poty病毒 (TEV) 演化, longitudinal samples from experimentally evolved 族群s in the natural host tobacco and from the alternative host pepper were phenotypically characterized and 遺傳ally analyzed. Temporal and compartmental variabilities of TEV 族群s were quantified using high throughput Illumina sequencing and 族群 遺傳 approaches. Of the two viral phenotypic traits measured, virulence increased in the novel host but decreased in the original one, and viral load decreased in both hosts, though to a lesser extent in the novel one. Dynamics of 族群 遺傳 多樣性 were also markedly different among hosts. 族群 heterozygosity increased in the ancestral host, with a dominance of synonymous
