Hydrosensing Project

Discovering How Plants Sense Water Stress

The Hydrosensing Project Team is on a mission to transform our understandingof how plants sense and respond to water availability. We aim to uncover the mechanisms plants use to perceive water stress, a key factor in their survival and productivity.

HYDROSENSING

a Synergy Project

By combining cutting-edge genomics, structural biology, biophysics and imaging approaches, we strive to revolutionize crop resilience and pave the way for climate-proof agriculture.

Join us as we explore new frontiers in plant science, working towards a future where crops are better equipped to withstand the challenges of a changing climate.

Image: Tissue-specific ABA responses are shaped by transporter-mediated hormone distribution. ABA and AB-ald (abscisic aldehyde) are delivered from source tissues (purple) to distinct target sites (red), where ABA drives physiological responses, including stomatal closure in guard cells, seed development and germination, suberin formation in the endodermis, and xerobranching in the root epidermis. Directional movement of ABA and its precursor AB-ald between tissues (black arrows) is mediated by multiple ABA delivery mechanisms. The spatial distribution of ABA transporters determines tissue-specific ABA accumulation and responses. ABA, abscisic acid. Credit: Current Opinion in Plant Biology

HYDROSENSING after 18 Months: Growing Knowledge and Growing Impact

While still being at an early stage of our 5-year journey, the HYDROSENSING project is moving forward with strong momentum. Over the past 18 months, we have advanced our scientific understanding of how plants perceive and respond to water, while also contributing to broader discussions about foundational plant science, agriculture,…
