  Future research should aim to validate the study's findings in other wheat varieties and environments. Future research should examine the potential for breeding programs to improve wheat heat tolerance by selecting for stomatal traits. Future research should investigate the molecular mechanisms underlying the relationship between stomatal traits and heat tolerance in wheat.

  Heat stress is a major constraint to global crop productivity, particularly in wheat. Stomata play a central role in balancing photosynthetic carbon assimilation and evaporative cooling, but the mechanisms underlying this process are not well understood. Breeding programs aimed at improving wheat heat tolerance are limited by a lack of understanding of the genetic architecture underlying stomatal traits.
