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
Soybean rust kidney beans, peas, leguminous forage crops such as trefoil and sweet clover and weeds such as kudzu. At the early stage of Asian Soybean Rust, it causes yellow mosaic discoloration on the upper surfaces of older foliage. At this stage, it is usually hard to identify since the symptoms are relatively small and poorly defined. Later as the disease continues to progress, the leaves will turn yellow and there will be lesions mostly on the undersides of the leaves and sometimes on petioles, stems or pods and premature defoliation can also be observed. Asian Soybean Rust produces two types of
