• Resumen

  • How do plants breathe? This research reveals how tiny structures called stomata—microscopic valves on leaves that regulate gas exchange—have evolved in angiosperms to balance water loss and gas exchange with remarkable precision. By combining plant anatomy, physiology and environmental signals, the study uncovers how innovations like stomatal hydroactive closure and guard cell-epidermal cell interaction boost water-use efficiency and drought resilience. From responses to light and vapour pressure to the impact of polyploidy on stomatal dynamics, the findings offer new insights into plant adaptability and open promising avenues for breeding climate-resilient crops.
