  • Introduction to Mycology
    INTRODUCTION TO MYCOLOGY The term "mycology" is derived from Greek word "mykes" meaning mushroom. Therefore mycology is the study of fungi. The ability of fungi to invade plant and animal tissue was observed in early 19th century but the first documented animal infection by any fungus was made by Bassi, who in 1835 studied the muscardine disease of silkworm and proved the that the infection was caused by a fungus Beauveria bassiana. In 1910 Raymond Sabouraud published his book Les Teignes, which was a comprehensive study of dermatophytic fungi. He is also regarded as father of medical mycology. Importance of fungi: Fungi inhabit almost every niche in the environment and humans are exposed to these organisms in various fields of life. Beneficial Effects of Fungi: 1. Decomposition - nutrient and carbon recycling. 2. Biosynthetic factories. The fermentation property is used for the industrial production of alcohols, fats, citric, oxalic and gluconic acids. 3. Important sources of antibiotics, such as Penicillin. 4. Model organisms for biochemical and genetic studies. Eg: Neurospora crassa 5. Saccharomyces cerviciae is extensively used in recombinant DNA technology, which includes the Hepatitis B Vaccine. 6. Some fungi are edible (mushrooms). 7. Yeasts provide nutritional supplements such as vitamins and cofactors. 8. Penicillium is used to flavour Roquefort and Camembert cheeses. 9. Ergot produced by Claviceps purpurea contains medically important alkaloids that help in inducing uterine contractions, controlling bleeding and treating migraine. 10. Fungi (Leptolegnia caudate and Aphanomyces laevis) are used to trap mosquito larvae in paddy fields and thus help in malaria control. Harmful Effects of Fungi: 1.

E-mail: [email protected] Received 15 July 2004; accepted 3 October 2004. Basidiomycete mycelia are ubiquitous in forest soils where they fulfil a range of key ecological functions. Population studies, based largely on basidiome collections, indicate that mycelia of many ectomycorrhizal and saprotrophic basidiomycetes can spread vegetatively for considerable distances through soil, but the extent to which these become physically or physiologically fragmented is unclear. This review considers aspects of the distribution, dynamics and translocatory activities of individual basidiomycete mycelia in forest soil, highlighting current gaps in our understanding and possible ways to address these. INTRODUCTION in soil have been constrained by a lack of suitable techniques for discrimination between them, but some On the basis of basidiome collections, it is evident that progress is now being made.

  • The Lifecycle of a Mushroom
    WEB TUTORIAL 21.1 The Lifecycle of a Mushroom Text Sections Section 21.3 Reproduction in Fungi, p. 354 Introduction Mushrooms have an unusual life cycle. After spores are released from mature fruit- ing bodies, they germinate to form hyphae. Collectively, the hyphae make up a branching web, called a mycelium. Hyphae derived from the spores of two differ- ent mating types then fuse to become one cell with two distinct nuclei. Thus begins a phase of life that is unique to fungi: the dikaryotic phase, in which cells in a fun- gal mycelium have two nuclei. This tutorial illustrates the relationships among these phases in the life cycle of a mushroom. Learning Objectives • Know the structures involved in each stage of a mushroom’s life cycle. • Understand why the life cycle of fungi is unique in the tree of life. Narration The Life Cycle of a Mushroom A mushroom is a member of a group of fungi called the Basidiomycota. Let's con- sider its life cycle, beginning with the spores that are produced by the mature fruit- ing body. A spore germinates, dividing by mitosis to produce a filament called a hypha. The hypha grows and branches to produce a filamentous network called a mycelium. The mycelium has a high surface-area-to-volume ratio, which allows the fungus to absorb nutrients efficiently. If the hyphae of different mating types meet, they are attracted to each other and fuse, forming a cell with two nuclei. This is an unusual condition for a cell; in the normal case, one cell has one nucleus.

  • The Dynamics of Hyphal Growth
    Myco!. Res. 99 (4): 385-394 (1995) Printed in Great Britain 385 Presidential address 1993 The dynamics of hyphal growth GRAHAM W. GOODAY Department of Molecular and Cell Biology, University of Aberdeen, Aberdeen AB9 lAS, UK This account reflects diverse aspects of hyphal growth and development that I have encountered since first becoming interested in fungi. Apical growth is discussed, with particular reference to the phenomena of hyphal maturation and the formation of helical hyphae. It is contrasted with cases of intercalary growth and reversed growth of hyphae. Localization of chitin synthesis at the apex and at other particular sites in the wall is described in detail. It is suggested that chitin microfibrils are synthesized at hyphal tips and at other sites by a transmembrane enzyme complex of several polypeptides allosterically regulated by effector molecules but also perhaps by local physical stress of the membrane. Behaviour of hyphae is discussed with examples of mating zygophores, of contact sensing of surfaces and of responses to applied electric fields. The hypha is the characteristic growth form of fungal cells. Its its extension by insertion of new material. Thus it must be most important feature is that it enables the fungus to explore progressively rigidified as it is transformed to become the and exploit new environments and substrates. It can also lateral wall of the hypha. Chiefly from studies of Wessels and differentiate to form a variety of structures, such as sporangia, conidiophores, rhizoids and fruit bodies. A major interest of mine for many years has been the many guises of hyphal growth, with the aim of understanding the mechanisms of these dynamic processes.

  • Red-Brown Blushing Morel—Morchella Rufobrunnea (Fig. 5)
    Ecology and Management of Morels Harvested From the Forests of Western North America Red-brown blushing morel—Morchella rufobrunnea (fig. 5). Description—Head: conical to subconical to ovoid when mature. Ribs: whitish to grayish when young, becoming yellowish, brownish, or brownish-yellow with age. Pits: vertically elongate when young, becoming irregularly shaped with age. Stalk: irregularly wrinkled near base with minute dark granules toward the top; whitish to cream, pale gray, darker grayish brown, yellowish toward base, blush- ing in irregular spots brown, brownish orange, or pinkish red to ferruginous when injured or maturing (both head and stalk), sometimes almost completely reddish brown. Spore size: (19-) 20–24 (-25.5) x (13-) 14–16 (-17) µm. Ecology—Growing in moist subtropical oak, sweetgum, white-alder (Clethra), and alder forests in the Xalapa region of Mexico. Perhaps also along coastal Cali- fornia in landscaping mulch. Comments—Kuo (2005, 2006) suggested that what has been identified as M. deliciosa in California is actually M. rufobrunnea. He also suggested that M. rufo- brunnea was the morel that Ower described cultivating in his first patent (Ower and others 1986), rather than M. esculenta. At the time of the patent, M. rufobrunnea had not yet been described and was not yet suspected as a separate species along coastal California. M. guatemalensis and M. herediana are other morel species that occur in subtropical regions of Mexico and Central America, but do not range further into North America (Guzmán and Tapia 1998).

  • Mycology: Unravelling the Riddle of the Filamentous Fungi
    Microbiology The picture shows different color mutants of Aspergillus nidulans. Wild type forms green spores which cover almost the entire colony. It is easy to generate mutants in which pigment biosynthesis is blocked at certain stages and thus a different pigment variant (yellow) or no pigments (white) are produced. Mutants are a great starting point for a molecular analysis. This approach has been used to study many cellular processes and made A. nidulans a model organism for lower eukaryotes and beyond. The diameter of a colony is about 1 cm. less well known is that they play a vital role, not only in generating nutrients, but also in plant nutrient uptake: every metre of plant root in the soil is associated with roughly a kilometre of symbiotic fungal hyphae, known as ‘mycorrhiza’, which take up nutrients and pass them to the plant. Filamentous fungi are important pathogens of crop plants, and in a few cases cause serious human disease, particularly in the immunocompromised. They have also been harnessed for biotechnological uses, including crucially in the production of antibiotics such With the help of the jellyfish green fluorescent protein (GFP) researchers visualised the microtubule as penicillin, other medicines, citric acid, cytoskeleton in Aspergillus nidulans. Round spores and foods such as soy sauce and cheese. To produced long hyphae, and microtubules are visible as long filaments in the cells.
