In the context of increasingly complex climate change, prolonged droughts are becoming one of the major challenges for agricultural production worldwide. Water scarcity not only reduces crop yields but also directly impacts food security and the sustainable development of the agricultural sector. Therefore, research and development of drought-tolerant plant varieties is a key objective for scientists.

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology has opened a breakthrough in biotechnology and plant breeding. With its ability to precisely, quickly, and efficiently edit genes, CRISPR allows researchers to directly intervene in genes related to drought tolerance, thereby creating plant varieties that are better adapted to arid conditions without affecting other important agronomic characteristics.

The application of CRISPR technology in breeding drought-tolerant crops not only helps improve agricultural productivity and quality but also contributes to mitigating the impact of climate change on agricultural production. This article will present the operating principles of CRISPR technology, its prominent applications in improving drought tolerance in crops, and the potential and challenges in implementing this technology in agricultural production.
