摘要

Climate change, with its increasing temperatures, is significantly disrupting global agricultural systems, and wheat, a key cereal crop faces severe challenges. Heat stress has emerged as a critical threat, accelerating wheat growth, leading to premature maturation, reduced grain filling, and ultimately lower yields. The situation is exacerbated by more frequent and intense heat waves, particularly in regions already struggling with water scarcity. Maintaining the delicate balance of temperature and water necessary for optimal wheat production is becoming challenging, posing a serious risk to global food security. Therefore, there is an urgent need to develop adaptive strategies with innovations in breeding and transgenic technologies crucial to improving wheat resilience to environmental stresses, especially to combat the growing impacts of heat stress. Modern tools like CRISPR/Cas9, Transcription Activator-Like Effector Nucleases, and Zinc Finger Nucleases have been instrumental in developing wheat varieties with improved traits. However, the future of wheat cultivation requires more than just resistance to a single stressor. As climate change intensifies, there is an urgent need for wheat varieties that can withstand multiple stresses, including heat, drought, and pests. Developing these multi-stress-tolerant cultivars is crucial for ensuring food security in a rapidly changing climate.
