Over the past decades host–parasite coevolution has received particular scientific interest because it is associated with very high selective constraints, resulting in fast and complex evolutionary dynamics that affect a large variety of trait functions (Woolhouse et al., 2002).On the one hand, parasite-induced reduction in host fitness enhances selection for host resistance mechanisms.

Fungi are by far the most common parasites of plants; the study of these fungi is a major component of the science of plant pathology. Less common, but frequently well known, are some flowering plants, such as mistletoe, that parasitize other plants.

"Parasites have evolved, through years of co-evolution with their host. The spores of one parasitic fungus, for example, invade an ant’s body, where the fungus grows and consumes the ant’s organs.
Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its host.Unlike commensalism and mutualism, the parasitic relationship harms the host, either feeding on it or, as in the case of intestinal parasites, consuming some of its food.However, parasites are different from saprophytes. Because parasites interact with other species, they.
If you want more data on life support than you know what to do with, try reading this NASA document.Otherwise, read on. For some great notes on spacecraft life support, read Rick Robinson’s Rocketpunk Manifesto essay. As a very rough general rule: one human will need an amount of mass/volume equal to his berthing space for three months of consumables (water, air, food).

One example of a parasitic fungus is Ceratocystis fagacearum, a fungus that causes the disease oak wilt, which quickly kills healthy oak trees. Fungi in the genera Alternaria and Cladosporium are also parasitic, taking up residence in wheat and other grain plants and causing blackpoint disease. Keep Learning.
Coevolution is the interactive evolution of two or more species that results in a mutualistic or antagonistic relationship. When two or more different species evolve in a way that affects one another’s evolution, coevolution is taking place. This interactive type of evolution is characterized by the fact that the participant life-forms are acting as a strong selective pressure upon one.

The fungus forces its host to climb up to the top of a plant, clamp down onto it to steady itself, and wait to die. Then, the fungus slowly emerges through the bug’s exoskeleton, forming a stalk up.
Many of these plants associate with fungi that are not related to the mycorrhizal fungi of green orchids, including ECM associates of trees, wood‐rotting and parasitic fungi. These associations have a high degree of host‐fungus specificity and species of Corallorhiza , Gastrodia and Galeola may only associate with a single fungal genus.

Abstract. Like other parasites that have intimate associations with their hosts, fungal parasites of plants show host specificity. Although the complete host range of a single fungal parasite is rarely known for certain (Heath 1985), it is generally assumed that any one species can successfully attack relatively few of the many species of extant flowering plants, and may even be restricted to.
