Gene-for-Gene Interactions in Rust Fungi and Rathjen explain how gene-for-gene interactions in rust fungi are important for economic gain. They suggest that knowing the genetics and co-evolution of gene-for-gene interactions can help strengthen plant immune systems, which will provide more efficient growth of crops. Gene-for-Gene Interactions in Rust Fungi The study of gene-for-gene interactions uncovers genetic components, evolutionary impacts, and ecological/economic implications between rust fungi and plants. Rust fungi utilize the gene-for-gene interaction to invade host plants. Conversely, host plants utilize the gene-for-gene interaction to prevent invasion of rust fungi. Gene-for-gene interactions between plants and rust fungi are helping us further understand the ecology and
Anaerobic organism using hydrogenosomes. Some organisms metabolise primarily using glycogen, for example the Nereid (worm)s and some polychaetes, or the juvenile form of the pork parasite "Trichinella spiralis" which causes trichinosis. Anaerobic organism An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present. (In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.) An anaerobic organism may be unicellular (e.g. protozoans, bacteria) or multicellular. For practical purposes, there are three categories of anaerobe: obligate anaerobes, which are harmed by the presence
