植物与它们的微生物组建立了关键的关系，并且通常被概念化为全生生物。尽管如此，全生生物理论还是引起了很多批评，特别是关于全生生物很少是一个选择单位的事实。在以前的工作中，我们讨论了植物微生物组如何被认为是一个“皮带上的生态系统”，它受到自然选择对植物性状的影响。我们提出，在驯化的植物中，植物微生物组的组装可以被有效地概念化为受到“双重束缚”，这包括驯化者对植物性状施加的人工选择的影响和从植物到微生物组的束缚。在这里，我们的方法驯化植物holobiont，简单地定义为一个社区的生物体，从社会进化的角度来看，并显示如何社区遗传力（社区选择的措施）补充的“双皮带”框架，提供一个社区层面的植物驯化及其对植物微生物相互作用的影响。我们还提出了简单的实验，可以进行调查是否植物驯化改变了社区选择的潜力，在holobiont水平。
Plants establish a pivotal relationship with their microbiome and are often conceptualized as holobionts. Nonetheless, holobiont theories have attracted much criticism, especially concerning the fact that the holobiont is rarely a unit of selection. In previous work, we discussed how the plant microbiome can be considered to be an ‘ecosystem on a leash’, which is subject to the influence of natural selection acting on plant traits. We proposed that in domesticated plants the assembly of the plant microbiome can usefully be conceptualized as being subject to a ‘double leash’, which encompasses both the effect of artificial selection imposed by the domesticator on plant traits and the leash from the plant to the microbiome. Here we approach the domesticated plant holobiont, simply defined as a community of organisms, from a community evolution point of view, and show how community heritability (a measure of community selection) complements the ‘double-leash’ framework in providing a community-level view of plant domestication and its impact on plant–microbe interactions. We also propose simple experiments that could be performed to investigate whether plant domestication has altered the potential for community selection at the holobiont level.
