Crop Plants, Water Use efficiency (WUE)

Current development stage

The development is currently applicable to GMO – transgenic plants


Most technologies to improve Water Use Efficiency (WUE) in plants involve enhancement of Abscisic Acid Production and/or ABA responding genes. However, these approaches have many drawbacks.

Our Innovation

The new technology allows increased water use efficiency, drought and stress resistance of potentially all crop plants, increased yield and accelerated flowering.

The researchers discovered an enzyme that plays a role in the coordination between photosynthesis and transpiration. Controlled expression of the enzyme in guard cells led to reduced transpiration and thus increased overall Water Use Efficiency.


The technology employs molecular and cellular mechanisms controlling whole-plant Water-Use Efficiency, water-potential homeostasis and crop productivity, under normal and abiotic stress conditions.


The technology could be implemented by seed companies open to GMO in crop plants.
