Bananas, including plantains (Musa spp.), are among the most widely cultivated fruit crops globally. However, various biotic and abiotic stresses hamper their production. The triploid chromosomal nature of most cultivated banana varieties poses significant challenges to conventional breeding efforts. Gene editing has recently emerged as a powerful tool to address these challenges. Among available technologies, CRISPR/Cas9 stands out for its precision, efficiency and relatively short development time. The CRISPR/Cas9 system operates through an RNA-guided endonuclease mechanism that introduces double-strand breaks (DSBs) at specific genomic locations. These targeted modifications result in heritable changes, making it a promising approach for developing stress-resistant banana varieties. CRISPR/Cas9 has been employed to manage biotic stress by combating bacterial diseases such as Xanthomonas Wilt (BXW) and viral infections including Banana Streak Virus (BSV) and Banana Bunchy Top Virus (BBTV). This involves editing susceptibility genes like Musa DMR6, or enhancing the expression of defense-related genes such as chitinase. For abiotic stress tolerance, genome editing and gene overexpression techniques have been utilized to increase resilience to environmental factors like drought, salinity and cold. Additionally, disruption of the 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) gene crucial in ethylene biosynthesis has been used to reduce ethylene production, thereby extending the shelf life of banana fruits. This review explores the potential of CRISPR/Cas9 and related gene editing technologies as transformative tools in improving stress tolerance in bananas, ultimately contributing to sustainable cultivation and global food security.
