Ploidy-level variation is common and can drastically affect organismal fitness. We focus on the potential consequences of this variation for parasite resistance. First, we elucidate connections between ploidy variation and key factors determining resistance, including allelic diversity, gene expression and physiological condition. We then argue that systems featuring both natural and artificially manipulated ploidy variation should be used to evaluate whether ploidy level influences host-parasite interactions.
倍性水平的变化很常见,会极大地影响生物个体的适应性。我们专注于这种变化对寄生虫抗性的潜在影响。首先,我们阐明了倍性变化与决定抗性的关键因素之间的联系,包括等位基因多样性、基因表达和生理状况。然后,我们认为应该利用同时具有自然和人为控制倍性变化的系统来评估倍性水平是否影响宿主-寄生虫相互作用。
