Viruses are thought to be fundamental in driving microbial diversity in the oceanic planktonic realm. That role and associated emerging infection patterns remain particularly elusive for eukaryotic phytoplankton and their viruses. Here we used a vast number of strains from the model system /Emiliania huxleyi Virus to quantify parameters such as growth rate (µ), resistance (R), and viral production (Vp) capacities. Algal and viral abundances were monitored by flow cytometry during 72-h incubation experiments. The results pointed out higher viral production capacity in generalist EhV strains, and the virus-host infection network showed a strong co-evolution pattern between and EhV populations. The existence of a trade-off between resistance and growth capacities was not confirmed.
病毒被认为是推动海洋浮游生物领域微生物多样性的重要因素。对于真核浮游植物及其病毒而言,这一作用以及相关的新出现感染模式仍然特别难以捉摸。在此,我们使用了来自模式系统/赫氏颗石藻病毒的大量菌株,以量化诸如生长速率(µ)、抗性(R)和病毒产生(Vp)能力等参数。在72小时的培养实验中,通过流式细胞术监测藻类和病毒的丰度。结果表明,泛嗜性EhV菌株的病毒产生能力更强,并且病毒-宿主感染网络显示出[此处原文缺失信息]和EhV种群之间有很强的共同进化模式。抗性和生长能力之间存在权衡这一观点未得到证实。
