摘要
Effective 族群 size (N-e) is a key parameter for understanding 演化ary processes, but it is generally not considered in 流行病學ological studies or in studying infections of individual hosts. Whether Ne has an effect on the onset of symptoms and viral accumulation in Tobacco etch 病毒 (TEV) infection of Nicotiana tabacum plants is considered here. Using mixtures of TEV variants carrying fluorescent markers, the dose dependence of N-e was confirmed, and the inoculation procedure was found to be the main source of variation in these experiments. Whereas the onset of symptoms was independent of N-e, there was less and more variable accumulation at 6 days postinoculation for small N-e values (N-e < 5). The observed variation in accumulation was not heritable, however, suggesting that this variation was
