AI Technical Summary
Technical Problem
Current methods to improve plant water use efficiency focus on reducing stomatal density, which can decrease CO2 availability for photosynthesis and slow plant growth, without effectively accelerating stomatal kinetics to balance carbon assimilation and water conservation.
Method used
Introducing mutations into the C-linker domain and the cytosolic N-terminal domain of stomatal voltage-gated potassium channels to alter channel clustering and voltage- and K+-dependencies, thereby enhancing guard cell membrane transport and accelerating stomatal movements.
Benefits of technology
This approach enhances water use efficiency and carbon assimilation by accelerating stomatal kinetics, allowing for increased growth and yield in crops without negatively impacting photosynthesis.

Abstract
The invention relates to methods of increasing stomatal function in plants, which leads to an increase in water use efficiency and ultimately an increase in biomass and yield. In particular the methods of the invention relate to modifying stomatal voltage-gated potassium channels to accelerate stomatal conductance and kinetics. Also described are plants expressing these modified channels and well as methods of producing such plants.
