Abstract

Plants associate with a wealth of microbes, collectively referred to as the plant microbiota, whose composition is determined by host plant genetics, immune responses, environmental factors and intermicrobial relations. Unsurprisingly, microbiota compositions change during disease development. Recent evidence revealed that some of these changes can be attributed to effector proteins with antimicrobial activities that are secreted by plant pathogens to manipulate host microbiota to their advantage. Intriguingly, many of these effectors have ancient origins, predating land plant emergence, and evolved over long evolutionary trajectories to acquire selective antimicrobial activities to target microbial antagonists in host plant microbiota. Thus, we argue that host-pathogen co-evolution likely involved arms races within the host-associated microbiota.

干预微生物群:真菌感染植物宿主的伎俩
植物与大量微生物(统称为植物微生物群)有联系,其组成由寄主植物遗传、免疫反应、环境因素和微生物间关系决定。毫不奇怪,微生物群的组成在疾病发展过程中会发生变化。最近的证据表明,其中一些变化可归因于植物病原体分泌的具有抗菌活性的效应蛋白,这些蛋白能操纵宿主微生物群,使其对自己有利。耐人寻味的是,这些效应蛋白中有许多起源古老,早于陆生植物的出现,并经过漫长的进化过程,获得了选择性抗菌活性,以宿主植物微生物群中的微生物拮抗剂为目标。因此,我们认为宿主与病原体的共同进化可能涉及宿主相关微生物群内部的军备竞赛。
