Plants and animals use chemical tags on their RNA molecules to fine-tune which genes are active during development and in response to environmental stress. This review maps three major tag types, how scientists detect them, and why they could matter for engineering climate-resilient crops.
Three RNA modification types, noncanonical caps, m6A, and pseudouridine, form a chemical regulatory layer above DNA that dynamically shapes gene activity during development
These RNA marks influence how plants and animals process, transport, and use genetic messages in response to both developmental stages and environmental stressors
New transcriptome-wide profiling tools have revealed the scope of these modifications, with potential applications in human disease therapy and climate-resilient crop breeding
