About this Research Topic
We welcome submissions of Original Research, Reviews, and Opinion articles encompassing the breadth of stomatal research. In particular, we encourage those that bridge knowledge gaps between the molecular genetics of stomatal development and physiology; model, non-model, and crop species; evo-devo and ecological processes.
To approach the vast continuum of stomatal research across scales, our Research Topic addresses the following themes and related questions:
1. Coordination of stomatal development with plant growth, development and environmental signaling.
How do changes in the core developmental program - at the gene sequence, protein expression, or cellular level - explain natural variation in stomatal traits (including stomatal function, density, size, or gsmax)?
2. The role of stomatal development in plant acclimation and adaptation to the environment.
How does intraspecies stomatal developmental plasticity facilitate environmental acclimation or improve physiological performance? How have stomatal morphology, patterning, and physiology been modified by plants to adapt to specific environments and evolutionary pressures?
3. Influence of stomatal development and function on plant resource use (e.g carbon, nutrients, and water), ecosystem processes, and global climate.
How important is the developmental program relative to guard cell mediated physiology? Does the balance shift at different scales (organismal, ecosystem, global)? How do stomata sense and respond to water availability and how does this affect C3, C4 and CAM photosynthesis in water-limited environments? How do stomatal traits feed back to ecosystem and environmental processes?
4. Selection for stomatal traits in plant evolution, crop domestication and breeding, and designing food for the future.
How have crop domestication and recent crop breeding affected stomatal traits and how can we exploit stomatal mechanisms and variation to develop the crops of the future?
