Moreover, the interaction dynamics between SynCom members and the host plant, as well as among the microbial members themselves, add another layer of complexity that needs to be understood and managed (Yin et al., 2022). 7.2 Ecological and environmental considerations The introduction of SynComs into agricultural ecosystems raises several ecological and environmental concerns. One primary concern is the potential impact on native microbial communities and the broader ecosystem. The introduction of non-native microbial strains could disrupt existing microbial networks and ecological balances, leading to unintended consequences (Pradhan et al., 2022). Additionally, the long-term ecological impacts of SynComs are not well understood, and there is a risk that these engineered communities could outcompete or displace native beneficial microbes, potentially leading to reduced biodiversity (Arnault et al., 2023). Furthermore, the environmental conditions, such as soil type and climate, can significantly influence the effectiveness and stability of SynComs, making it challenging to predict their performance across different agricultural settings (Sai et al., 2022). 7.3 Economic and scalability issues The economic viability and scalability of SynComs are critical factors that need to be addressed for their widespread adoption. Developing and producing SynComs at a commercial scale can be cost-prohibitive, particularly given the need for precise formulation and quality control (Shayanthan et al., 2022). Additionally, the variability in field performance necessitates extensive field trials and optimization, which can be resource-intensive and time-consuming (Yin et al., 2022). The scalability of SynComs also depends on the ability to produce them in large quantities while maintaining their functional integrity and effectiveness. This requires advancements in biotechnological processes and infrastructure to support large-scale production and distribution (Sai et al., 2022). 7.4 Regulatory and safety concerns The deployment of SynComs in agriculture is subject to regulatory scrutiny and safety concerns. Regulatory frameworks for the use of genetically engineered microorganisms in agriculture are still evolving, and there is a need for clear guidelines and standards to ensure the safe use of SynComs (Pradhan et al., 2022). Safety concerns include the potential for horizontal gene transfer between SynCom members and native microbes, which could lead to the spread of undesirable traits (Shayanthan et al., 2022). Additionally, there is a need to assess the potential risks to human health and the environment, including the possibility of SynComs affecting non-target organisms or entering the food chain (Arnault et al., 2023). Addressing these regulatory and safety concerns is essential to gain public trust and ensure the responsible use of SynComs in agriculture. 8 Future Directions and Perspectives 8.1 Emerging trends and technologies in SynCom engineering The field of synthetic microbial communities (SynComs) is rapidly evolving, with several emerging trends and technologies poised to enhance their application in agriculture. One significant trend is the integration of computational methods, such as machine learning and artificial intelligence, to screen and identify beneficial microbes, thereby improving the process of determining the best combination of microbes for desired plant phenotypes (Souza et al., 2020). Additionally, advances in omics technologies, including genomics, proteomics, and metabolomics, are being leveraged to gain deeper insights into plant-microbe interactions and to design more effective SynComs (Pradhan et al., 2022). The use of non-invasive real-time phenotyping platforms to monitor plant physiological responses to SynCom inoculation is another promising development, allowing for the precise measurement of temporal variations in plant traits under different environmental conditions (Armanhi et al., 2021). Furthermore, remote sensing technologies are being employed to assess crop status at field scale, integrating big data into predictive and prescriptive management tools to enhance agricultural resilience (Jung et al., 2020).
