Stomatal dynamics in Alloteropsis semialata arise from the evolving interplay between photosynthetic physiology, stomatal size and biochemistry

Y Zhou, CP Osborne - Plant, Cell & Environment, 2024‏ - Wiley Online Library
C4 plants are expected to have faster stomatal movements than C3 species because they
tend to have smaller guard cells. However, little is known about how the evolution of C4 …
