Development of Genomic Editing Technologies for Creating Climate-Resilient Crops in Tropical Regions

Abstract

Climate change poses a severe threat to global food security, particularly in tropical regions where rising temperatures, erratic rainfall, soil salinization, and increased pest pressures significantly constrain crop productivity. In response to these challenges, this study investigates the development and application of advanced genomic editing technologies for creating climate-resilient crops tailored to tropical agroecosystems. Using a mixed experimental methodology, precision genome-editing tools including CRISPR/Cas systems, base editors, and prime editors were employed to modify key stress-responsive regulatory genes associated with drought, heat, and salinity tolerance. Quantitative assessments were conducted through molecular validation, controlled-environment phenotyping, and multi-location tropical field trials to evaluate editing efficiency, yield stability, and stress tolerance indices across edited crop genotypes. The results demonstrate consistently high editing efficiency and significant improvements in yield performance and stress tolerance compared to non-edited controls under adverse environmental conditions. Multivariate analyses further confirmed strong correlations between genome-editing precision and phenotypic resilience traits. Visual analytics and hybrid plots reinforced the robustness of genotype performance across environments, highlighting the stability and reproducibility of genome-edited traits. Collectively, the findings underscore the transformative potential of genome editing for enhancing crop resilience to climate-induced stresses in tropical regions. This study provides critical experimental evidence supporting the integration of genome-editing technologies into sustainable breeding programs and contributes to advancing climate-smart agriculture and long-term global food security.
