Sustainable agriculture demands innovative strategies to enhance crop productivity through plant–microbe interactions. Synthetic communities (SynCom) offer a targeted approach for this purpose. This study investigated the molecular mechanisms underlying sugarcane responses and the dynamics of its rhizosphere microbial community following inoculation with a SynCom called MetG2 at the gene expression level. A greenhouse inoculation experiment was conducted, followed by shotgun metagenome and metatranscriptome sequencing. Multi-omics analysis revealed significant temporal shifts in the microbial community, with an up-regulation of genes related to flagellar assembly, chemotaxis, quorum sensing, and biofilm formation, particularly within Proteobacteria, indicating active microbial movement toward root surfaces. Additionally, genes associated with nutrient acquisition, hormone synthesis, siderophore production, and volatile organic compound (VOC) synthesis were enriched, suggesting stimulated beneficial microbial activities. Sugarcane plants also exhibited dynamic responses, including the up-regulation of hormone-related genes (auxin, cytokinin, salicylic acid) and nutrient transporter genes (nitrate, phosphate, potassium, sulfur). Stress resistance genes such as trehalose 6-phosphate phosphatase, phenylalanine ammonia-lyase, expansin, and antioxidant-related genes were also induced. These findings highlight the complex molecular interplay between sugarcane and microbes after MetG2 inoculation, supporting its potential as a sustainable strategy to enhance crop productivity and resilience. © 2025 Elsevier B.V., All rights reserved.
