由于人为气候变化，干旱的频率和严重程度正在增加，并且已经限制了世界许多地区的作物系统生产力。植物微生物群中很少有微生物类群能够在包括水分亏缺在内的非生物胁迫事件下对其宿主的适应性和生产力做出潜在贡献。然而，微生物群落是复杂的，需要考虑多个共存的生物群体的综合工作，以更好地了解整个微生物组如何应对环境压力。我们假设水分亏缺胁迫将不同地塑造细菌，真菌和原生生物微生物组组成，并影响玉米和甜菜根际微生物的相互作用。我们使用扩增子测序来描述在灌溉和缺水条件下生长的玉米和甜菜根际中的细菌、真菌和原生生物群落。水分亏缺处理对细菌组成的影响强于宿主物种，而原生生物则相反。这些结果表明，不同的微生物王国对环境压力和宿主因素有不同的反应。水分亏缺也影响了王国内和王国间的微生物协会，其中原生生物类群在水分亏缺条件下形成了一个单独的集群。我们的研究结果有助于阐明农业根际环境中细菌，真菌和原生生物群落组装和共存的环境和宿主驱动因素的影响。
The frequency and severity of drought are increasing due to anthropogenic climate change and are already limiting cropping system productivity in many regions around the world. Few microbial groups within plant microbiomes can potentially contribute towards the fitness and productivity of their hosts under abiotic stress events including water deficits. However, microbial communities are complex and integrative work considering the multiple co‐existing groups of organisms is needed to better understand how the entire microbiome responds to environmental stresses. We hypothesize that water deficit stress will differentially shape bacterial, fungal, and protistan microbiome composition and influence inter‐kingdom microbial interactions in the rhizospheres of corn and sugar beet. We used amplicon sequencing to profile bacterial, fungal, and protistan communities in corn and sugar beet rhizospheres grown under irrigated and water deficit conditions. The water deficit treatment had a stronger influence than host species on bacterial composition, whereas the opposite was true for protists. These results indicate that different microbial kingdoms have variable responses to environmental stress and host factors. Water deficit also influenced intra‐ and inter‐kingdom microbial associations, wherein the protist taxa formed a separate cluster under water deficit conditions. Our findings help elucidate the influence of environmental and host drivers of bacterial, fungal, and protistan community assembly and co‐occurrence in agricultural rhizosphere environments.
