How do plants translate environmental stimuli into biological action? The answer lies in “calcium signatures”—the complex, tightly regulated Ca²⁺ fluxes that define how plants respond to the world around them.

In this webinar, Prof. Alex Costa will present advanced, non-invasive imaging approaches to study in vivo Ca²⁺ dynamics from single organelles to whole organisms, using transgenic plants expressing genetically encoded fluorescent Ca²⁺ indicators combined with wide-field, stereomicroscopy, and confocal imaging.
