Abstract

The adventof fluorescent probesand the characterization of their photochemical properties in the past years allowed significant advances in the studies ofspatiotemporal cellular processes within complex and crowded systems.Dyesareindeedextremely useful tools forthe visualization ofcellular and subcellular structures present in living cells, as well asto studytheirdynamicand molecular composition or physiological changes. There are some areas of plant cell biology that have been more challenging to explore due to the physiology and organization of certain endomembrane compartments. In this study we characterize the labeling properties of cresyl violet as quick and inexpensive imaging agent for tracking endosomes, vacuole compartments which are usually very differentiated and categorized as more acidic as well as acidic plant compartments. Its photobleaching, labelling and cytotoxic properties are compared with other well-known and currently most used synthetic and molecular probes.
