Data from Pliant pathogens: Estimating viral spread when confronted with new vector, host, and environmental conditions

To determine the effects of new conditions (host, vector, and nutrient) on pathogen spread rate, we introduced a vector-borne viral plant pathogen, Barley Yellow Dwarf Virus PAV (BYDV-PAV) into hosts, vectors, and host nutrient supplies that it had not encountered for thousands of viral generations. We quantified pathogen prevalence over the course of two serial inoculations under the new conditions.

为探究宿主、介体与营养三类新环境条件对病原物传播速率的影响，我们将媒介传播型植物病毒病原——大麦黄矮病毒PAV株系（Barley Yellow Dwarf Virus PAV, BYDV-PAV）接种至该病毒历经数千个病毒复制世代未曾接触过的宿主、介体与宿主营养基质中。我们在上述新环境条件下，通过两次连续接种实验对病原的流行率进行了定量测定。
