摘要
Background: Theory suggests that high virulence could hinder between-host 傳播 of microparasites, and that virulence therefore will evolve to lower levels. Alternatively, highly virulent microparasites could also curtail host development, thereby limiting both the host resources available to them and their own within-host effective 族群 size. In this case, high virulence might restrain the 突變 supply rate and increase the strength with which 遺傳漂變 acts on microparasite 族群s. Thereby, this alternative explanation limits the microparasites' potential to adapt to the host and ultimately the ability to evolve lower virulence. As a first exploration of this hypothesis, we evolved Tobacco etch 病毒 carrying an eGFP fluorescent marker in two semi-permissive host 物種, Nicotiana benthamiana and Datura stramo
