When viruses infect microbial cells, their phenotypes depend on the host's genotype and on the environmental conditions. Here we describe such an effect in laboratory strains of the chlorovirus PBCV-1 and its algal host Chlorella variabilis. We studied the growth of six virus isolates, and found that the mean lysis time was 1.34±0.05 times longer at multiplicity of particles (MOP) 10 than at MOP 1. We could not detect any associated changes in burst size. This is a novel plastic trait for chloroviruses, and we hypothesize that it is caused by our specific laboratory algae.

叶绿素-小球藻相互作用中高粒子复数下的延迟裂解时间。

当病毒感染微生物细胞时，它们的表型取决于宿主的基因型和环境条件。在这里，我们描述了这种对氯病毒 PBCV-1 及其藻类宿主变异小球藻实验室菌株的影响。我们研究了六种病毒分离株的生长，发现在粒子复数 (MOP) 10 时的平均裂解时间比在 MOP 1 时长 1.34±0.05 倍。我们无法检测到爆发大小的任何相关变化。这是氯病毒的一种新的塑料特性，我们假设它是由我们特定的实验室藻类引起的。
