Gene-for-Gene Interactions in Rust Fungi 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 evolution of plant-microbe interactions, specifically pathogenicity. There are implications of gene-for-gene interactions for fitness in real world populations. Co-evolution due to gene-for-gene interactions can help us understand evolutionary advantages and disadvantages. Co-evolution can help understand how the host-pathogen interactions
Rust for corrosion of iron and its alloys, such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called rust. Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen. Rebar used in underwater concrete pillars, which generates green rust, is an example. Although rusting is generally a negative aspect of iron, a particular form of rusting, known as "stable rust," causes the object to have a thin coating of rust over the top, and if kept in low relative humidity, makes the "stable" layer
