摘要
Knowledge about the distribution of 突變al fitness effects (DMFE) is essential for many 演化ary models. In recent years, the properties of the DMFE have been carefully described for some microorganisms. In most cases, however, this 資訊 has been obtained only for a single environment, and very few studies have explored the effect that environmental variation may have on the DMFE. Environmental effects are particularly relevant for the 演化 of multi-host parasites and thus for the 湧現 of new pathogens. Here we characterize the DMFE for a collection of twenty single-nucleotide substitution mutants of Tobacco etch poty病毒 (TEV) across a set of eight host environments. Five of these host 物種 were naturally infected by TEV, all belonging to family Solanaceae, whereas the other three were partially suscept
