Image courtesy of Brian Duarte (Hamelin lab, Forest Conservation Sciences). 3D reconstruction of the confocal images acquired with the Leica Stellaris 8; Cronartium ribicola (causal agent of white pine blister rust) aeciospores on Ribes nigrum (black currant leaves), germinating and entering through the Stomata, 3 days after inoculation. The fungus was stained with Alexa fluor 488, and the plant was stained with propidium iodide. The Z-depth of the image is colour coded with red (top of the sample) to blue (bottom of the sample) in the range of 250 micrometers in depth (left image), and 110 micrometers in depth (right image).
