The uses of fungi are numerous. Ravenalia 5. Importance in Human Life ADVERTISEMENTS: The following points highlight the five important genera of family pucciniaceae. Fungi are important decomposers in most ecosystems. Study of bacteria — Bacteriology Study of fungi — Mycology. CHARACTERISTICS OF FUNGI 6. Ans. WE WILL LEARN General characteristics of fungi Structure of fungi Economic Importance Pathogenicity Brief intro of some fungi 4. All fungal genera of medical importance can be classified into 5 sexual groups which are Ascomycetes, Basidiomycetes, Zygomycetes, Chytridiomycetes or Chytrids and Fungi Imperfecta (Doctor Fungus USA, 2007).

Trichoderma viride and T. harzianum are other examples which are used against a large number of soil-borne pathogens. Most fungi are not dangerous, but some types can be harmful to health. Most of the species are heteroecious and demicyclic, the telial stage occurs on Gymnosperms while […] Mycorrhizal fungi are essential for the growth of most plants. The fungus is also commercially important. 5 million fungal species is a reasonable estimate, the vast majority of all extant fungi are yet to be named. However, due to their ability to convert organic dead matter into mineral resources, they play an important role in the global substance flow. Some pathogenic fungi are opportunistic, meaning that they mainly cause infections when the host’s immune defenses are compromised and do not normally cause illness in healthy individuals.

Many saprophytic fungi decompose plant and animal debris and continuously remove it from the man’s environment. Fungi, as food, play a role in human nutrition in the form of mushrooms, and also as agents of fermentation in the production of bread, cheeses, alcoholic beverages, and numerous other food preparations. RNA polymerase II is a necessary enzyme involved in the production of a type of RNA called messenger RNA (mRNA). Fungi are one of the most important microorganisms in our environment. What Is the Economic Importance of Fungi? The play a number of important roles in medicine and in commercial agriculture. Let us have a look at some of the fields where fungi are really important. They play an important role in medicine by yielding antibiotics, in agriculture by maintaining soil fertility, are consumed as food, and forms the basis of many industries. Uromyces.
