RESEARCH 

Plants need to assimilate CO2 for photosynthesis and, at the same time, prevent excessive loss of water. Therefore, land plants have developed stomata, which regulate the exchange of gases between the atmosphere and the interior of the leaf. Each stomatal pore is mediated by two guard cells that increase and decrease in size, thereby controlling the rate of transpiration and the diffusion of CO2. Over 95% of plant water is lost through stomatal pores. For this reason, opening and closing of the stomata are tightly regulated by physiological and environmental factors.

 

Our world is going through dramatic climate change, which forecasts water scarcity, elevated world temperatures, extreme colds and dramatic increase in atmospheric CO2. Stomatal conductance is mediated by these environmental factors which dramatically affect crop plants physiology, viability, growth, productivity and eventually yield.

 

In our lab, we use physiological, biochemical and molecular tools to study the different aspects of climate change on plant transpiration regulation. Our research focuses, on exploring mechanisms and pathways that involves in stomatal conductance regulation in response to CO2, drought and cold stress.  We combine applicative and basic science to advance knowledge and provide with practices for agricultural problems.
