Abstract Rust fungi are phylogenetically very old pathogens attacking cereals and other plants. The life cycle of Puccinia graminis involves five different spore types on two alternate hosts, barberry and cereals or grasses. It is therefore suitable as an exemple of rusts in teaching. In collaboration with John Webster, its life cycle has been documented for the first time. With the help of time lapse and cinemicrography processes such as germination, formation and discharge of spores were observed. The complicated nuclear behaviour is also shown. Graphs are used to structure, explain and summarize the topic. This video can be used to teach students at university or schools, but is also appropriate for private study.
