Salinization of the soils is one of the most prominent problems threatening global food security. Root microbiome engineering using biofertilizers provides a sustainable way to increase agricultural productivity. Halophytes, which are extremely salt-tolerant plants, can tolerate up to 1300 mM NaCl. Members of the halophytic root microbiome now provide a promising solution to meet the increased demand in the agricultural output. Here, we explore the members of this microbiome and explain the plant growth-promoting functions of them. We discuss the manipulation of the root microbiome with synthetic microbial communities including keystone microorganisms of the halophytic root microbiome. Importantly, we provide a simple method in R software to find these putative keystone taxa using network analysis. We believe this strategy will provide a valuable tool for future studies performing the combined investigation of the root bacteria and fungi of halophytes.

部署盐生植物根部微生物组以提高农作物的耐盐性

土壤盐渍化是威胁全球粮食安全的最突出问题之一。使用生物肥料的根微生物组工程学提供了提高农业生产率的可持续方式。盐植物是极耐盐的植物，可耐受高达1300 mM的NaCl。盐生根微生物群的成员现在提供了一种有前途的解决方案，可以满足农业产量不断增长的需求。在这里，我们探索了该微生物组的成员，并解释了它们的植物生长促进功能。我们讨论了包括合成盐菌根微生物组的关键微生物在内的合成微生物群落对根微生物组的操作。重要的是，我们在R软件中提供了一种简单的方法，可以使用网络分析来找到这些假定的梯形分类群。
