Older technologies (e.g. aequorin) enabled detection of cytosolic Ca2+signatures triggered by different stimuli at low spatial resolutions. Recent developments in microscopy techniques coupled with the use of plants expressing genetically encoded fluorescent Ca2+ sensors are now revealing a hidden world where Ca2+ increases not only occur in individual, stimulated cells but propagates as waves within the plant body. The use of specific targeting sequences or tissue-specific promoters for sensor expression, is also enabling investigation into Ca2+dynamics in different subcellular compartments and in different tissues.

In the webinar, the technical aspects of the imaging tools needed to perform Ca2+ imaging in plants will be presented.
