摘要
Effective 族群 size (N-e) determines the strength of 遺傳漂變 and the frequency of co-infection by multiple genotypes, making it a key factor in viral 演化. Experimental estimates of N-e for different plant 病毒es have, however, rendered diverging results. The independent action hypothesis (IAH) states that each virion has a probability of infection, and that virions act independent of one another during the infection process. A corollary of IAH is that N-e must be dose dependent. A test of IAH for a plant 病毒 has not been reported yet. Here we perform a test of an IAH infection model using a plant RNA 病毒, Tobacco etch 病毒 (TEV) variants carrying GFP or mCherry fluorescent markers, in Nicotiana tabacum and Capsicum annuum plants. The number of primary infection foci increased linearly with dose, and w
