Rust fungus on a rose leaf, SEM C017 / 7132
Rust fungus on a rose leaf. Coloured scanning electron micrograph (SEM) of rust fungus (Phragmidium sp.) spores emerging from a rose (Rosa sp.) leaf (brown). Spores are the reproductive cells of a fungus. Two types of spore are seen, the over-wintering teleutospores (long, khaki) and the summer uredospores (bottom left, bright green). Rust fungi are parasitic on both wild and cultivated plants, often causing severe disease. Magnification: x440 when printed at 10 centimetres tall

EDITORS COMMENTS
This print showcases the intricate world of rust fungus on a delicate rose leaf. Through the lens of a scanning electron microscope, we are granted a mesmerizing glimpse into the reproductive cells of this parasitic organism. The brown hue of the leaf serves as an eerie backdrop for the emergence of Phragmidium sp. spores, which play a crucial role in spreading disease among both wild and cultivated plants. The image reveals two distinct types of spores: teleutospores and uredospores. The long, khaki-colored teleutospores represent over-wintering cells, while the bright green uredospores signify those produced during summer months. This visual distinction highlights the adaptability and resilience of rust fungi in their quest to survive and reproduce. With its magnification set at x440 when printed at 10 centimeters tall, this photograph allows us to appreciate the microscopic details that often go unnoticed by our naked eyes. It is through such scientific exploration that we gain deeper insights into plant pathology, mycology, and microbiology. As we marvel at this stunning display captured by Microfield Scientific Ltd. , let us not forget that behind these vibrant colors lies a potential threat to our beloved roses and other plant species. This image serves as a reminder for researchers and enthusiasts alike to continue studying these fascinating organisms in order to develop effective strategies for combating their destructive impact on our natural environment.
