During 450 million years of diversification on land, plants and microbes have evolved together. This is reflected in today's continuum of associations, ranging from parasitism to mutualism. Through phylogenetics, cell biology, and reverse genetics extending beyond flowering plants into bryophytes, scientists have started to unravel the genetic basis and evolutionary trajectories of plant-microbe associations. Protection against pathogens and support of beneficial, symbiotic, microorganisms are sustained by a blend of conserved and clade-specific plant mechanisms evolving at different speeds. We propose that symbiosis consistently emerges from the co-option of protection mechanisms and general cell biology principles. Exploring and harnessing the diversity of molecular mechanisms used in nonflowering plant-microbe interactions may extend the possibilities for engineering symbiosis-competent and pathogen-resilient crops.
在陆地 4.5 亿年的多样化过程中，植物和微生物共同进化。这反映在当今从寄生到共生的连续体中。通过系统发生学、细胞生物学和超越开花植物进入苔藓植物的反向遗传学，科学家们已经开始揭示植物-微生物共生的遗传基础和进化轨迹。对病原体的保护和有益的共生微生物的支持是由不断进化、速度不同的保守和类群特异性植物机制的混合来维持的。我们提出，共生关系始终是从保护机制和一般细胞生物学原理的共同选择中产生的。探索和利用非开花植物-微生物相互作用中使用的分子机制的多样性，可能会扩展工程共生能力和抗病原体作物的可能性。
