摘要
Pepino mosaic 病毒 (PepMV) is an emerging pathogen that causes severe 經濟 losses in tomato crops in the Northern hemisphere. After its first identification, the new viral strain PepMV-CH2 has been isolated in several countries worldwide. In order to further understand the 演化ary dynamics of PepMV before and after PepMV-CH2 湧現, we analyzed a collection of PepMV isolates from southeastern Spain, estimating the rate of PepMV molecular 演化 and the coalescence process for the effective number of PepMV infections using a 貝氏 系統發育 approach. Our results show that the rate of PepMV molecular 演化 was 5.570 x 10(-3) substitutions/site/year, a value which is approximately an order of magnitude higher than the rates recently reported for other plant RNA 病毒es. Moreover, PepMV-CH2 was estimated to have originat
