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
Stem rust healthy crop about three weeks before harvest into a black tangle of broken stems and shriveled grains by harvest. Stem rust of cereals causes yield losses in several ways: Stem rust on wheat is characterized by the presence of uredinia on the plant, which are brick-red, elongated, blister-like pustules that are easily shaken off. They most frequently occur on the leaf sheaths, but are also found on stems, leaves, glumes and awns. On leaves they develop mostly on the underside but may penetrate to the upperside. On leaf sheaths and glumes pustules rupture the epidermis, giving a ragged appearance. Towards
