Plants associate with a wide diversity of microorganisms. Some microorganisms engage in intimate associations with the plant host, collectively forming a metaorganism. Such close coexistence with plants requires specific adaptations that allow microorganisms to overcome plant defenses and inhabit plant tissues during growth and reproduction. New data suggest that the plant immune system has a broader role beyond pathogen recognition and also plays an important role in the community assembly of the associated microorganism. We propose that core microorganisms undergo coadaptation with their plant host, notably in response to the plant immune system allowing them to persist and propagate in their host. Microorganisms, which are vertically transmitted from generation to generation via plant seeds, putatively compose highly adapted species and may have plant-beneficial functions. The extent to which plant domestication has impacted the underlying genetics of plant-microbe associations remains poorly understood. We propose that the ability of domesticated plants to select and maintain advantageous microbial partners may have been affected. In this review, we discuss factors that impact plant metaorganism assembly and function. We underline the importance of microbe-microbe interactions in plant tissues, as they are still poorly studied but may have a great impact on plant health.

植物代谢产物中的相互作用和共适应。

植物与各种各样的微生物相关。一些微生物与植物寄主密切联系，共同形成一种新生物。与植物的这种紧密共存要求进行特殊的适应，以使微生物能够克服植物的防御能力，并在生长和繁殖过程中栖息于植物组织中。新数据表明，植物免疫系统在病原体识别之外具有更广泛的作用，并且在相关微生物的群落组装中也起着重要作用。我们建议核心微生物与它们的植物宿主进行共适应，特别是对植物免疫系统的响应，使它们在宿主中得以持久和繁殖。微生物通过植物种子在世代之间垂直传播，推测组成高度适应的物种，并可能具有植物有益的功能。植物驯化在多大程度上影响了植物-微生物协会的基础遗传学，仍然知之甚少。我们提出，驯化植物选择和维持有利的微生物伴侣的能力可能已经受到影响。在这篇综述中，我们讨论了影响植物代谢组装和功能的因素。我们强调了微生物-微生物在植物组织中的相互作用的重要性，因为它们的研究仍很少，但可能对植物健康产生重大影响。我们提出，驯化植物选择和维持有利的微生物伴侣的能力可能已经受到影响。在这篇综述中，我们讨论了影响植物代谢组装和功能的因素。我们强调了微生物-微生物在植物组织中的相互作用的重要性，因为它们的研究仍很少，但可能对植物健康产生重大影响。我们提出，驯化植物选择和维持有利的微生物伴侣的能力可能已经受到影响。在这篇综述中，我们讨论了影响植物代谢组装和功能的因素。我们强调了微生物-微生物在植物组织中的相互作用的重要性，因为它们的研究仍很少，但可能对植物健康产生重大影响。
