Soil microbiomes are extremely complex, with dense networks of interconnected microbial species underpinning vital functions for the ecosystem. In advanced agricultural research, rhizosphere microbiome engineering is gaining much attention, as the microbial community has been acknowledged to be a crucial partner of associated plants for their health fitness and yield. However, single or combined effects of a wide range of soil biotic and abiotic factors impact the success of engineered microbiomes, as these microbial communities exhibit uneven structural and functional networks in diverse soil conditions. Therefore, once a deep understanding of major influential factors and corresponding microbial responses is developed, the microbiome can be more effectively manipulated and optimized for cropping benefits. In this mini-review, we propose the concept of a microbiome-mediated smart agriculture system (MiMSAS). We summarize some of the advanced strategies for engineering the rhizosphere microbiome to withstand the stresses imposed by dominant abiotic and biotic factors. This work will help the scientific community gain more clarity about engineered microbiome technologies for increasing crop productivity and environmental sustainability.Key points⢠Individual or combined effects of soil biotic and abiotic variables hamper the implementation of engineered microbiome technologies in the field.⢠As a traditional approach, reduced-tillage practices coinciding with biofertilization can promote a relatively stable functional microbiome.⢠Increasing the complexity and efficiency of the synthetic microbiome is one way to improve its field-application success rate.⢠Plant genome editing/engineering is a promising approach for recruiting desired microbiomes for agricultural benefit.
