Abstract:Summary
Climate change‐induced drought is a major threat to agriculture. C4 crops have a higher water use efficiency (WUE) and better adaptability to drought than C3 crops due to their smaller stomatal morphology and faster response. However, our understanding of stomatal behaviours in both C3 and C4 Poaceae crops is limited by knowledge gaps in physical traits of guard cell (GC) and subsidiary cell (SC).
We employed infrared gas exchange analysis and a stomatal assay to explore the relationship between GC/SC … Show more
