Pin-ItThis microanimal lives in a self-built tube attached to waterplants. We see the rotifer using fast moving cilia to create a vortex. This enables it to sweep in food particles like algae. Inside the organism we can also see jaw-like structures that grind the food.

A sheet of light is used to illuminate the plant (Arabidopsis thaliana), from the side while collecting the emitted light at a perpendicular axis. The plant grows in an upright position in the microscope’s specimen chamber. While the leaves remain in the air, the root system is perfused with liquid medium. and root stably expresses the early endosome/exosome marker 35S::GFP-RabA1d. The quick endosomes move with up to 10 µm/s, which presents a serious imaging challenge. This technique allows new insides in the dynamics of endosomal compartments in plant cells. The Arabidopsis line was kindly provided by Tobias Berson and Jozef Samaj.
