Abiotic stresses such as extreme temperatures, drought, and high soil salinity affect the plant growth and crop production and pose serious threat to global food security. Due to their immobility and ongoing exposure to environmental signals, including extremely high (hot) and low (cold) temperatures, plants have evolved sophisticated molecular regulation systems to adapt to extreme conditions and maintain their normal growth and development. Recent studies show that in plants, noncoding RNAs (ncRNAs) play an important role to abiotic stresses. These ncRNAs include such as small interfering RNAs (siRNAs), long noncoding RNAs (lncRNAs), and microRNAs (miRNAs). Recent advances in molecular biology and biotechnology have introduced new ways to improve crop resilience using the recent CRISPR-Cas gene editing and synthetic ncRNA applications. This prospect is very exciting; however, delivery systems, off–target effects, and the potential ethical considerations of genetic manipulation are practical obstacles that need to be addressed before they can be used in crop improvement. More research and technological innovation are needed in order to overcome these barriers. Furthermore, these ncRNAs can be used to enhance plant abiotic stress tolerance through gene expression, hormonal crosstalk, and epigenetic modifications to allow for dynamic adaptation of the plant to changing environmental conditions, salt, and heat stress. Sustainable solutions to achieving improved crop resilience, maintaining food security, and mitigating the effects of climate change in agriculture can be achieved by using ncRNAs, and advanced biotechnological approaches can harness them.
