Calcium ion dynamics in roots: Imaging and analysis

Abstract

Calcium sensors are indispensable tools to study the role of Ca2+ and visualize Ca2+ dynamics during biological processes. Over the past years, the field of Ca2+ imaging has strongly expanded by the development of a wide palette of sensors and optimization of sample handling. Here, we provide guidelines for imaging of the Ca2+ sensor R-GECO1 in Arabidopsis thaliana roots which can be interpolated to other intensiometric Ca2+ sensors. Furthermore, we demonstrate a procedure for image analysis of the acquired time-lapse recordings.
