Research Interest

I'm a molecular physiologist interested in elucidate the molecular and cellular mechanisms controlling whole-plant Water-Use Efficiency, water-potential homeostasis and crop productivity, under normal and abiotic stress conditions. Mainly we focused in small membrane proteins which function as water channels – Aquaporins (AQPs).

Our research hypothesis is that AQPs might be good candidates for controlling the plant's osmotic and hydraulic conductivity, and since some AQPs have been reported to conduct CO2, there was a strong likelihood that they could be used to improve osmotic stress tolerance and Water-Use Efficiency in plants (Our agricultural model plant is tomato (Solanum lycopersicom)).

Major Projects

  1. The role of Solanaceae aquaporins in improving plant vigor, abiotic stress tolerance and yield production.
  2. The regulatory role of aquaporins in controlling plant cell water permeability.
  3. Developing a high-throughput automated screening system for the on-line collection and analysis of data from many plants simultaneously.  Pinpointing plants showing improved transpiration-use efficiency under normal and stress conditions at an early developmental stage.
  4. Development of quantitative criteria to screen forest trees regarding their resistance to water deficiency and water-use efficiency.
  5. The role of C3 bundle-sheath cells as the plant's first line of defense against embolisms and as a sensor for stress-induced ABA.
