摘要
Tomato black ring 病毒 (TBRV) is a worldwide‐distributed RNA 病毒 infecting a wide range of different host plants, including crop 物種, trees, shrubs, and weeds. Here, we investigated the molecular 演化 of TBRV and its adaptability to different plant 物種. The TBRV‐Pi isolate was used to generate five independent 演化 lineages serially passaged in either quinoa, tobacco, or tomato plants. After 15 passages, the 遺傳 variability present in all the lineages was characterized for the movement (MP) and coat (CP) coding cistrons. We addressed two main questions: to what extent does the amount of 遺傳 variability in the TBRV 基因組 depend on the host 物種, and are there host 物種‐specific adaptive 突變s? Overall, 201 different nucleotide substitutions emerged during the 演化 experiment, with some of them appearing multipl
