真菌异养植物是由它们独特的物种相互作用定义的，大多数已经进化到利用植物-真菌互惠互利来获得碳资源。一组不同的植物已经进化出真菌异养，并且各种各样的真菌已经被利用。真菌异养通常与对特定真菌的高度特异性有关，这可能会对这些植物生物学的其他方面产生影响，例如分布模式和多样化。人们还推测，它将影响这些植物参与的更广泛的物种相互作用网络，例如与传粉者的相互作用。例如，长期以来一直假设真菌异养植物应该倾向于自花授粉或通性授粉策略。我们回顾了这些假设的证据，并讨论了这些植物的相互作用网络的各种案例研究。很明显，真菌异养生活方式对这些植物的影响超出了它们的营养。因此，真菌异养提供了很好的案例研究的影响，一个专门的相互作用对植物生态学和进化的多个方面，包括授粉，草食动物，和物种形成。
Mycoheterotrophic plants are defined by their unique species interactions—the majority have evolved to exploit plant–fungal mutualisms for carbon resources. A phylogenetically diverse group of plants have evolved mycoheterotrophism, and a wide variety of fungi have been exploited. Mycoheterotrophy is often associated with high specificity towards particular fungi, and this is likely to have consequences for other aspects of these plants’ biology, such as distribution patterns, and diversification. It has also been speculated that it will impact the wider network of species interactions that these plants engage in, such as those with pollinators. For example, it has long been hypothesized that mycoheterotrophic plants should be predisposed to either self-pollination or a generalist pollination strategy. We review the evidence for these hypotheses and discuss various case-studies into the interaction networks of these plants. It is clear that the mycoheterotrophic lifestyle has consequences for these plants beyond their nutrition. As such, mycoheterotrophy offers excellent case-studies into the effects of a specialized interaction on multiple aspects of plant ecology and evolution, including pollination, herbivory, and speciation.
