As climate change becomes increasingly complex, prolonged drought is emerging as one of the major challenges facing agricultural production worldwide. Water scarcity not only reduces crop yields but also directly affects food security and the sustainable development of the agricultural sector. Therefore, researching and developing crop varieties with improved drought tolerance has become an important objective for scientists.

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology has marked a major breakthrough in biotechnology and crop breeding. With its ability to edit genes precisely, rapidly, and efficiently, CRISPR enables researchers to directly modify genes associated with drought tolerance, thereby developing crop varieties that can better adapt to dry conditions without compromising other important agronomic traits.

The application of CRISPR technology in breeding drought-tolerant crop varieties not only helps improve crop yields and agricultural product quality but also contributes to mitigating the impacts of climate change on agricultural production. This article explores the working principles of CRISPR technology, its key applications in improving crop drought tolerance, and the potential and challenges of implementing this technology in practical agricultural production.
