The increasing salinity of agricultural lands highlights the urgent need to improve salt tolerance in crops, a critical factor for ensuring food security. Epigenetic mechanisms are pivotal plant adaptation stress. This review elucidates complex roles DNA methylation, histone modifications, variants, and non-coding RNAs fine-tuning gene expression response It emphasizes how heritable changes, which do not alter sequence but significantly impact phenotype, contribute this adaptation. methylation is notably prevalent under high-salinity conditions associated with changes that enhance resilience salt. Modifications histones, including both acetylation, directly linked regulation salt-tolerance genes. presence such as H2A.Z, altered stress, promoting environments. Additionally, RNAs, miRNAs lncRNAs, intricate regulatory network also underscores importance understanding these epigenetic developing stress memory enhancing tolerance.

Plants often encounter challenging environmental factors, including intense sunlight, drought, extreme heat, cold temperatures, salinity, excessive metals, and nutrient shortages, which can heavily affect their growth survival. In this regard, L-ascorbic acid (AsA) is not only an essential for human health but also plays a significant role in plant responses to stresses, regulating various functions during development, redox signaling, phytohormone biosynthesis. The growing need cope with climate change, together the advancement of CRISPR/Cas9-editing technologies, stimulated new opportunities enhance AsA biosynthesis improve crop stress tolerance. review, we discuss regulation abiotic response mechanisms. We explore latest advancements CRISPR/Cas9 applications, challenges as tools modifying genes associated metabolism, aiming develop crops more tolerant resilient changes.
