在气候变化中养活不断增长的世界人口需要优化粮食生产的可靠性、资源利用和环境影响。帮助实现这些目标的一种方法是整合有益的植物微生物组-即，提高植物生长、养分利用效率、非生物胁迫耐受性和抗病性的技术--用于农业生产。这种整合将需要学术研究人员、行业研究人员和农民之间的大规模努力，以了解和管理现代农业系统背景下的植物-微生物组相互作用。在这里，我们确定了该领域研究的优先事项：（1）开发具有相关微生物培养物集合和参考基因组的作物植物和非作物植物的模型宿主-微生物组系统，（2）定义这些模型系统中的核心微生物组和宏基因组，（3）阐明合成的、功能可编程的微生物组组装的规则，（4）确定植物-微生物组相互作用的功能机制，以及（5）表征和改进植物基因型-环境-微生物组-管理的相互作用。实现这些目标应加快我们设计和实施有效的农业微生物组操作和管理战略的能力，这反过来将为世界粮食供应的消费者和生产者带来红利。
Feeding a growing world population amidst climate change requires optimizing the reliability, resource use, and environmental impacts of food production. One way to assist in achieving these goals is to integrate beneficial plant microbiomes—i.e., those enhancing plant growth, nutrient use efficiency, abiotic stress tolerance, and disease resistance—into agricultural production. This integration will require a large-scale effort among academic researchers, industry researchers, and farmers to understand and manage plant-microbiome interactions in the context of modern agricultural systems. Here, we identify priorities for research in this area: (1) develop model host–microbiome systems for crop plants and non-crop plants with associated microbial culture collections and reference genomes, (2) define core microbiomes and metagenomes in these model systems, (3) elucidate the rules of synthetic, functionally programmable microbiome assembly, (4) determine functional mechanisms of plant-microbiome interactions, and (5) characterize and refine plant genotype-by-environment-by-microbiome-by-management interactions. Meeting these goals should accelerate our ability to design and implement effective agricultural microbiome manipulations and management strategies, which, in turn, will pay dividends for both the consumers and producers of the world food supply.
