Chrysanthemum white rust in diameter, but may turn brown as the tissue becomes necrotic. On the underside of the leaf, the spots develop into pink or white pustules that become prominent as the teliospores develop. Chrysanthemum white rust Chrysanthemum white rust is a disease of plants caused by the fungus Puccinia horiana that infects species of the genus "Chrysanthemum". Chrysanthemum white rust was first identified in Japan, although it is now established throughout Asia, Europe, South America. It has been found in the United States, Australia, and New Zealand on several occasions, but early detection and eradication efforts have prevented the disease from
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
