Rust (fungus) fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are obligate plant pathogens that only infect living plants. Infections begin when a spore lands on the plant surface, germinates, and invades its host. Infection is limited to plant parts such as leaves, petioles, tender shoots, stem, fruits, etc. Plants with
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
