摘要

Abiotic stress factors such as drought, salinity, extreme temperatures, and oxidative stress significantly limit crop productivity and threaten global food security. Traditional breeding and transgenic approaches have been employed to enhance stress tolerance, but they are often time-consuming and face regulatory hurdles. The advent of CRISPR/Cas genome editing technology has revolutionized plant genetic engineering by enabling precise modifications to stress-responsive genes. This review explores recent advancements in CRISPR/Cas-based genome editing for improving abiotic stress resilience in crops. We discuss the mechanisms of CRISPR/Cas systems, their applications in stress tolerance, and emerging approaches such as multiplex genome editing, base editing, and AI-assisted CRISPR. Furthermore, we highlight challenges, ethical considerations, and future directions for integrating CRISPR into agricultural biotechnology. This review underscores the potential of CRISPR-based strategies in developing climate-resilient crops to ensure sustainable food production in the face of global climate change.
