[Webinar] Ion transport in stomata – From mechanism to the potentials in improving plant fitness

11:18, 19/04/2022

Most living activities on Earth are fueled by a phenomenon occurring in plant, algae, and some groups of bacteria, the photosynthesis. This process uses energy from light to convert CO2 to sugar and releases O2 as a byproduct. To acquire CO2 required for photosynthesis, higher plants have to trade off their precious water through evaporation. Maintaining the balance between controlling water loss and uptaking CO2 for photosynthesis is a crucial task assigned for stomata, the microscopic pores formed by pairs of guard cells on the leaf surface. Since the first observation of potassium accumulation in the pair of guard cells in 1905 by Macallum, the mechanism controlling stomatal movement has been intensively studied. More than a century of research has revealed a complex picture of how plant sophistically manipulates the aperture of these tiny pores in response to environmental stimuli. The wealth of knowledge about guard cell ion transport in the model plant Arabidopsis allows researchers to explore the more complex stomatal structure often found in many important crop species. Understanding the mechanism controlling the function of those stomata potentiates the enhancement of the crop plant fitness, which in turn, will have a strong impact on the food security.
