尽管人们普遍认识到微生物可以增强植物对环境胁迫的耐受性，但微生物介导暴露反应的性质尚不清楚。我们通过检查微生物介导植物对盐度升高的反应是否取决于环境和宿主固有的因素来解决这一缺陷。我们通过利用从两个 100 多年沿海沼泽种子库中回收的美洲鲽鱼基因型的祖先和后代群体进行普通花园实验，评估了对比环境条件相对于宿主基因型、起源和进化的影响。我们比较了S。根据植物基因型、种源和年龄组，在高盐度和低盐度胁迫下，有或没有本地土壤接种的情况下，美洲龙的生产力和性状变异以及相关的内生微生物群落。 S的微生物介导的大小和方向。美洲鳄对盐度升高的反应因个体基因型、起源以及基因型变异的时间变化和G × E（基因与环境）相互作用而异。植物性状与内圈群落结构之间的关系不同。我们的研究结果表明，植物-微生物关联和植物胁迫的微生物介导不仅依赖于环境，而且是动态的。我们的结果还表明，进化可以通过改变微生物赋予植物对全球变化相关压力的耐受性的方式来塑造沼泽生态系统的命运。
Although it is becoming widely appreciated that microbes can enhance plant tolerance to environmental stress, the nature of microbial mediation of exposure responses is not well understood. We addressed this deficit by examining whether microbial mediation of plant responses to elevated salinity is contingent on the environment and factors intrinsic to the host. We evaluated the influence of contrasting environmental conditions relative to host genotype, provenance and evolution by conducting a common‐garden experiment utilizing ancestral and descendant cohorts ofSchoenoplectus americanusgenotypes recovered from two 100+ year coastal marsh seed banks. We comparedS. americanusproductivity and trait variation as well as associated endophytic microbial communities according to plant genotype, provenance, and age cohort under high and low salinity stress with and without native soil inoculation. The magnitude and direction of microbial mediation ofS. americanusresponses to elevated salinity varied according to individual genotype, provenance, as well as temporal shifts in genotypic variation and G × E (gene by environment) interactions. Relationships differed between plant traits and the structure of endosphere communities. Our findings indicate that plant‐microbe associations and microbial mediation of plant stress are not only context‐dependent but also dynamic. Our results additionally suggest that evolution can shape the fate of marsh ecosystems by altering how microbes confer plant tolerance to pressures linked to global change.
