Soybean rust on the leaves of soybean plants and eventually kills the plants. The disease has caused serious yield loss of soybeans. In the areas where this disease is common, the yield losses can be up to 80%. In 2002, USDA reported 10-60% of yield losses in South America and Africa. Soybean rust is caused by two types of fungi, "Phakopsora pachyrhizi" and "Phakopsora meibomiae". It affects several important commercial plants, however, most notable for soybeans. Asian Soybean Rust can infect and reproduce on 90 known plant species, 20 of which are found in the United States, such as, soybeans, dry beans,
Mimicry in plants of signals. Cryptic mimicry in plants is usually achieved visually. The South American "Boquila trifoliata", of the Lardizabalaceae family, is a climbing vine with a highly variable phenotype. It is capable of mimicking the leaf features of plant species that it clings to, adopting color shape and size. By camouflaging its leafy appendages, "Boquila" lowers its rate of herbivory. Mimicry in plants In evolutionary biology, mimicry in plants is where a plant organism evolves to resemble another organism physically or chemically, increasing the mimic's Darwinian fitness. Mimicry in plants has been studied far less than mimicry in animals, with fewer
