All plants host diverse microbial assemblages that shape plant health, productivity, and function. While some microbial effects are attributable to particular symbionts, interactions among plant-associated microbes can nonadditively affect plant fitness and traits in ways that cannot be predicted from pairwise interactions. Recent research into tripartite plant–microbe mutualisms has provided crucial insight into this nonadditivity and the mechanisms underlying plant interactions with multiple microbes. Here, we discuss how interactions among microbial mutualists affect plant performance, highlight consequences of biotic and abiotic context-dependency for nonadditive outcomes, and summarize burgeoning efforts to determine the molecular bases of how plants regulate establishment, resource exchange, and maintenance of tripartite interactions. We conclude with four goals for future tripartite studies that will advance our overall understanding of complex plant–microbial interactions.

三方共生作为理解植物与微生物相互作用的模型。

所有植物都具有多种微生物组合,这些组合可塑造植物的健康状况,生产力和功能。虽然某些微生物作用可归因于特定的共生体,但植物相关微生物之间的相互作用可以以无法从成对相互作用中预测的方式非加性地影响植物的适应性和性状。对三方植物-微生物共生关系的最新研究为这种非可加性以及植物与多种微生物相互作用的潜在机制提供了重要的见识。在这里,我们讨论了微生物共生者之间的相互作用如何影响植物的生长性能,突出了非依赖性结果对生物和非生物背景依赖性的后果,并总结了为确定植物如何调节建立,资源交换和维持三方相互作用的分子基础而进行的迅速努力。
