Abstract This chapter describes the procedure for globally analyzing fluorescence lifetime imaging (FLIM) data for the observation and quantification of Förster resonance energy transfer (FRET) in live plant cells. The procedure is illustrated by means of a case study, for which plant protoplasts were transfected with different visible fluorescent proteins and subsequently imaged using two-photon excitation FLIM. Spatially resolved fluorescence lifetime images were obtained by application of global analysis using the program Glotaran, which is open-source and freely available software. Using this procedure it is possible to extract the fraction and distance of interacting species between, or conformational changes within proteins, from complex experimental FRET–FLIM datasets, even at low signal-to-noise ratios. In addition, the software allows excluding inherently present autofluorescence from the plant cells, which improves the accuracy of the FRET analysis. The results from the case study are presented and interpreted in the context of the current scientific understanding of these biological systems.
