Extractions: [Prev] [Next] [Index] http://users.caribnet.net/~lec/types.html Title: Mycorrhizae The roots of almost all higher plants are known to form mutualistic symbioses with fungi. These are termed mycorrhizae (fungus roots, from the Greek: mykes = mushroom or fungus and rhiza = root). Allen (1991) defined a mycorrhiza as " a mutualistic symbiosis between plant and fungus localised in a root or root-like structure in which energy moves primarily from plant to fungus and inorganic resources move from fungus to plant Fungi of very diverse kinds, belonging to all the major groups, take part in mycorrhizae. Based on morphology and the species involved, several different types are recognised. These are described below. The types can be distinguished by their positions along two gradients, from a lack of penetration of cortical cells (ectomycorrhizae) to penetration (vesicular-arbuscular mycorrhizae) and from an enclosed (ectomycorrhizae) to open root (vesicular-arbuscular mycorrhizae). Any natural ecosystem normally contains a mixture of types of mycorrhizal associations The main mycorrhizal response is one of increased efficiency of mineral uptake especially of poorly mobile ions and there is a voluminous literature dealing with the nutritional benefits that plants derive from mycorrhizal associations. Mycorrhizae are also involved in the transfer of nutrients from components of soil minerals and organic residues to solution, and in nutrient cycling in an ecosystem.

Extractions: Mycorrhizae Spores Most plant species exploit the soil with the help of beneficial microorganisms called mycorrhizal fungi. The fine threads that make up the fungus branch between soil particles, grow into decomposing organic matter, even explore the shells of dead insects, where they find phosphorus and other vital nutrients. The nutrients are then passed back to the roots of the plant. The word Mycorrhizae comes from Greek roots (appropriately enough). It refers to any of several types of associations between plant roots and soil fungi. Mycorrhizae offers several benefits to the host plant, including faster growth, improved nutrition, greater drought resistance, and protection from pathogens. Benefits to the plant community, especially important in revegetation, are higher plant species diversity and improved soil structure. Omni Mycorrhizae can Benefit the Growth and Health of Plants. Mycorrhizae is Critical to the Health and Well Being of Plants Especially in Soils that have been Disturbed and are in need of Reclamation. The Management of Soil Biology is still a new Concept to many Growers, but many Soil Scientists now believe that the Planned use of Omni Mycorrhizae will be the next big Advancement in Plant Culture, both in Horticultural Food Crops and Ornamentals. Omni Mycorrhizae is the Result of Many Years of Research and Thousands of Growth Tests and is Recognized Internationally as the Best Available.

Extractions: In practical terms, these fungal organisms attach to a plant's root system and then search the surrounding soil to bring nutrients, particularly phosphorus, to their host plant. A plant with the right species of mycorrhizae can uptake ten times more nutrients, creating a very vigorous and healthy plant, needing much less fertilizer. Some plants have thick, fleshy roots which are not efficient (such as citrus, grapes, asparagus, tomatoes, melons, squash, and many fruit trees). These plants depend on mycorrhizae and may not even survive without it. We have several of the best species available for use right now. Our inoculant has been propagated in sterile greenhouse conditions, and it comes in dry granular form for long shelf life. We sell a mixture of the most beneficial species, including

Extractions: 46. Molecular cloning and characterization of phosphate transporters from arbuscular mycorrhizal associations. Maria J. Harrison, H. Liu, I.E. Maldonado-Mendoza and M. L. van Buuren. The Samuel Roberts Noble Foundation, Plant Biology Division, 2510 Sam Noble Pkwy, Ardmore, Oklahoma 73401. Arbuscular mycorrhizal (AM) fungi are soil borne fungi that form mutualistic associations with the majority of species of land plants. The fungi are obligate symbionts and colonize the cortex of the plant root in order to obtain carbon from their plant hosts. The association is also beneficial for the plant as the fungi assist the plant with the aquisition of phosphate and other mineral nutrients from the soil. Our aim is to investigate the molecular mechanisms underlying phosphate transport in the symbiosis. Towards this goal we have isolated cDNA clones encoding phosphate transporters from roots of M. truncatula colonized with the AM fungus Glomus versiforme. cDNA clones from both the fungus and the plant were obtained and both encode proteins that are predicted to contain 12 membrane spanning domains, a secondary structure that is typical of membrane transporters from prokaryotes and eukaryotes. The cDNAs were expressed in yeast where they were able to complement a yeast phosphate transport mutant, therefore indicating that the encoded proteins are functional phosphate transporters. Phosphate transporters have been cloned previously from Neurospora and Saccharomyces.

August, 1994. Authors : Dwayne L. Stenlund, Robert L. Jacobson, and Iris D. Charvat. Department of Plant Biology, University of Minnesota, 1445 Gortner Avenue, St. Paul, MN 55108. Sponsoring Organization : Minnesota Department of Transportation, Office of Research Administration, 200 Ford Building Mail Stop 330, 117 University Avenue, St. Paul, MN 55155. All phases of the project were successful. The survey indicated that differences in VA mycorrhizae composition exist between different sites. It is possible to produce VA mycorrhizae in a greenhouse by culturing on live plant hosts. The VA mycorrhizae produced was successfully installed along with seed into field plots and did form mycotrophic associations with newly planted prairie species. Preliminary results obtained from this project indicate that further investigation is warranted.

Extractions: The term "mycorrhizae" comes from the Greek "myco" or fungus and "rhiza" or root and literally means "fungusroot." Mycorrhizae have been described as perhaps the ultimate in reciprocal parasitism (symboisis) wherein the fungus supplies the higher plant partner with mineral nutrients and plant growth hormones and protects the roots against pathogens, and the higher plant supplies the fungus with energy substrates. Almost all higher plants are dependent upon one of the mycorrhizal associations outlined in Table XIX, as only crucifers, chenopods, sedges, and aquatic plants are thought to be non-mycorrhizal.

Extractions: Here is a classic picture of mycorrhizae. These pictures are high resolution and will look fantastic on computers with modern video cards. This is the mycorrhizal fungus Laccaria laccata on ponderosa pine. Note the bifuricate shape of the mycorrhizae. You can see the fungal sheath (white area), hyphae, and hyphal strands (if you have 400x vision!). Thank you Jim Trappe for the slide! This is what the outer fungal sheath of a mycorrhizae actually looks like. As the micrograph shows the hyphae are about 1 micron in width. The bar at the bottom is 10 microns. Note the clamp connections i.e. those raised bulbous looking things! Some of the little dots are (likely) bacteria. Yes, the soil bacteria probably have some interaction with the fungus. In this photo you are looking at the cross section of a feeder root in mycorrhizal association with a fungus. In the center of the picture you can see the xylem. The large cells are cortical cells. Moving outwards look closely and you will see that the fungus has pushed itself between the cortical cells (Hartig Net: named for Dr. Hartig). Finally, there is the fungal sheath on the outside. The bar in the picture (lower left) is 10 microns. Another close up!

Extractions: Last Updated January 17, 2002 Note on titles Background Among vascular plants families, Ericaceae is unique for the number of distinct mycorrhizal types that have evolved within it. It is also an interesting case where the mycorrhizal types of different genera more accurately followed than did floral morphology or other traditional morphological features. Until the last decade, most plant systematists divided the ericad clade into a number of closely related families, such as Ericaceae, Empetraceae, Epacridaceae, Monotropaceae, Pyrolaceae, Rhodendraceae, Vacciniaceae, etc, usually in the order Ericales. The fact that these plants were closely related was not disputed, but the morphological differences among the different genera led to an understandable desire to separate them. For instance, Arbutus is a woody tree with fleshy fruits, Vacciniums (including the familiar cranberries, blueberries and huckleberries) are shrubs with berries, but Ericas have woody capsules, often with reduced leaves, Empetrums have reduced, often wind pollinated flowers
