Approaches to address heat stress (HS) challenges (IMAGE)

Diagram of potential approaches to mitigate the harmful effects of HS on crops. Identifying favorable alleles from germplasm resources through forward or reverse genetics and breeding heat-tolerant varieties is fundamental to overcoming the effects of HS. Given the variable environment, exploring rare alleles with enhanced functions, such as thermomemory, combined stress tolerance, and stress response–growth balance, is essential. Genome editing offers a rapid, targeted method to create beneficial mutations. Additionally, developing low-cost, eco-friendly plant regulators provides a complementary approach to alleviate the effects of HS, especially as understanding HS mechanisms and mass-producing heat-tolerant crops remain long-term challenges.
