世界人口的指数增长正在满足全球对可耕地的不断增长的需求，这是一种已经处于高需求状态的资源。这一趋势导致在次干旱和半干旱土地上的耕作增加，这些土地上水资源有限，加上一系列环境压力，往往严重降低作物产量。缓解与干旱气候相关的非生物胁迫的传统方法是培育耐胁迫品种，这是一项时间和劳动密集型的冒险，通常忽略了作物生长的土壤环境的复杂生态背景。近年来，研究试图鉴定能够赋予植物宿主相同胁迫耐受性的微生物共生体，基因组技术的新发展极大地促进了此类研究。在这里，我们强调了这些基于共生体的方法的许多优点，并主张更广泛地认识到作物物种作为不同微生物群落的生态位，这些微生物与植物宿主相互作用，在波动的环境条件下茁壮成长。
The exponential growth in world population is feeding a steadily increasing global need for arable farmland, a resource that is already in high demand. This trend has led to increased farming on subprime arid and semi-arid lands, where limited availability of water and a host of environmental stresses often severely reduce crop productivity. The conventional approach to mitigating the abiotic stresses associated with arid climes is to breed for stress-tolerant cultivars, a time and labor intensive venture that often neglects the complex ecological context of the soil environment in which the crop is grown. In recent years, studies have attempted to identify microbial symbionts capable of conferring the same stress-tolerance to their plant hosts, and new developments in genomic technologies have greatly facilitated such research. Here, we highlight many of the advantages of these symbiont-based approaches and argue in favor of the broader recognition of crop species as ecological niches for a diverse community of microorganisms that function in concert with their plant hosts and each other to thrive under fluctuating environmental conditions.
