作物病原体因其对宿主的快速适应而臭名昭著。我们仍然对它们的生命周期的演变以及是否可能存在健身组件之间的权衡知之甚少，限制了这些病原体的进化潜力。本研究探讨了小麦叶锈菌产孢能力与潜育期之间的平衡关系。使用简单的多变量（manova）技术，我们表明两个性状之间的协方差受宿主和病原体的共同控制，其中宿主基因型（57%）、病原体基因型（18.4%）和基因型×基因型相互作用（12.5%）的贡献。我们还发现了变化的迹象和强度的病原体的遗传相关性，当测量不同的主机品种。我们的研究结果表明，这些重要的病原体的生活史特征不自由地响应定向选择，精确的进化轨迹是偶然的相互作用的主机和病原体的遗传身份。
Crop pathogens are notorious for their rapid adaptation to their host. We still know little about the evolution of their life cycles and whether there might be trade-offs between fitness components, limiting the evolutionary potential of these pathogens. In this study, we explored a trade-off between spore production capacity and latent period in Puccinia triticina, a fungal pathogen causing leaf rust on wheat. Using a simple multivariate (manova) technique, we showed that the covariance between the two traits is under shared control of host and pathogen, with contributions from host genotype (57%), pathogen genotype (18.4%) and genotype × genotype interactions (12.5%). We also found variation in sign and strength of genetic correlations for the pathogen, when measured on different host varieties. Our results suggest that these important pathogen life-history traits do not freely respond to directional selection and that precise evolutionary trajectories are contingent on the genetic identity of the interacting host and pathogen.
