摘要

United Nations Framework Convention on Climate Change (UNFCCC) at Conference of the Parties (COP30; 2025) highlights the urgent need to accelerate climate action and substantially reduce greenhouse gases (GHGs: CH₄ and N₂O) emissions from rice-based ecosystems. Although, agronomic practices have so far achieved 24–46% reductions in CH₄ and N₂O emissions across diverse ecologies, additional mitigation strategies need to be explored for meeting country specific commitment for GHGs emissions reduction. The strategies could be unlocked through biotechnological interventions targeting both the rice plant and its associated microbiome. Plant-mediated innovations could include manipulation of aerenchyma orientation, alteration of root exudation patterns, development of low-nitrogen-efficient and aerobic cultivars, transfer of C₄ photosynthetic traits into rice, introgression of genes/QTLs for reduced tillering, photosynthate reallocation, mitochondrial enzyme modification and engineering rice to express nosZ gene for N₂O reduction. Microbiome-centric interventions encompass enhancement of methanotrophic activity, introduction of beneficial endophytic methanotrophs, deployment of genetically engineered bacteria with elevated N₂O-reducing enzyme (N₂O reductase) activity within rice tissues, and the use of Synthetic Microbial Communities (SynComs) and engineered archaeal communities. In this review, we have documented futuristic biotechnological strategies and discussed the supporting evidence demonstrating how these approaches can regulate the mechanistic pathways of GHGs emissions from rice ecosystems. Collectively, the document highlights the substantial potential as well as the scientific and practical challenges of leveraging biotechnology not only for modifying rice plants but also for optimizing their associated microbiome to achieve higher and sustainable reductions in GHGs emissions from rice.
