Customized plant microbiome engineering for food security.

Optimizing beneficial plant–microbe interactions can significantly enhance plant growth and resilience, which may be achievable through a targeted step-by-step process using customized microbiome engineering. 'Plant/microbe-friendly' soils can be prepared through traditional and targeted soil amendments to increase microbial diversity and soil fertility to suit specific plant cultivation needs. 'Microbe-friendly' plants and genotypes should be chosen because different crops and varieties vastly differ in their ability to benefit from microbes. 'Plant-friendly' microbiomes can be generated by applying suitable functional microbial inoculants with optimal formulations and supportive substrates. Microbiome breeding, microbiome transplanting, and the use of artificial microbial consortia to fill microbiome functional deficiencies are promising emerging areas that warrant further validation. Plant microbiomes play a vital role in promoting plant growth and resilience to cope with environmental stresses. Plant microbiome engineering holds significant promise to increase crop yields, but there is uncertainty about how this can best be achieved. We propose a step-by-step approach involving customized direct and indirect methods to condition soils and to match plants and microbiomes. Although three approaches, namely the development of (i) 'plant- and microbe-friendly' soils, (ii) 'microbe-friendly' plants, and (iii) 'plant-friendly' microbiomes, have been successfully tested in isolation, we propose that the combination of all three may lead to a step-change towards higher and more stable crop yields. This review aims to provide knowledge, future directions, and practical guidance to achieve this goal via customized plant microbiome engineering.
