Abstract

Water is a key factor in plant life. Therefore, reaching and holding water is a crucial part in plant survival. Plants sense water through a set of sensors which includes sensors for water activity (potential), for specific components of water potential, or for specific solutes contributing to water potential and for hydraulic signals. While these sensors are common to different plants and other organisms, their functions and modes of action are yet far from being understood. It is also unknown how these sensing mechanisms are linked to cellular and whole-plant responses to changes in water status in the soil or in the atmosphere. Advanced technologies that would provide means for single-cell physiological manipulations together with high-throughput noninvasive real-time monitoring systems of shoots and roots and advanced biochemistry and structural studies at atomic resolution of sensor proteins and protein complexes are imperative for understanding water sensing by plants.
