Summary
Changing variable environments are causing plants to respond to repeated high temperatures impairing plant growth and reducing crop yields. To engineer crops with improved thermotolerance, it is crucial to understand how plants tolerate repeated high temperatures. Plants that experience moderate high temperatures can survive subsequent extreme lethal heat. This acquired heat tolerance is critical for plant survival, but its underlying mechanisms are unclear. Photosynthesis, the process by which plants use sunlight to produce food, is one of the most heat sensitive functions in plant cells. Und
