Non-coding RNAs (ncRNAs) play a crucial role in plant stress responses, offering potential for developing stress-resilient crops. Key challenges include the accurate identification, annotation, and functional validation of ncRNAs, as well as distinguishing correlation from causation in ncRNA-mediated stress responses. Additionally, proving the functional roles of ncRNAs in abiotic stress tolerance under chemically induced conditions remains a significant challenge. Looking ahead, the integration of advanced technologies, such as high-throughput sequencing, single-cell RNA analysis, and CRISPR-based approaches, promises to enhance our understanding of ncRNA functions. Research into ncRNA-driven epigenetic modifications could further reveal their role in transgenerational stress adaptation. Moreover, genetic engineering and molecular breeding strategies incorporating ncRNAs hold potential for developing stress-resilient crops. By addressing these challenges and leveraging emerging technologies, researchers can unlock the full potential of ncRNAs in enhancing plant stress tolerance. A deeper understanding of ncRNA functions will be instrumental in breeding climate-resilient crops, a crucial step toward ensuring global food security in the face of increasing environmental uncertainties.
