Extractions: There is a lot of confusion about mycorrhizae, a word that describes the common relationship between plants and beneficial fungi. While the modern gardener is just beginning to learn about mycorrhizae, it has actually been around for millions of years. In fact, the fossil record shows that mycorrhiza appeared at about the same time as plants appeared on land. Under natural conditions, many plants, especially California native plants, live in close association with soil microorganisms. The roots of almost all higher plants are known to form "mutualistic symbioses" with fungi. This is termed "mycorrhizae" which means fungus-root. This term is derived from the Greek, "mykes" which means mushroom or fungus and "rhiza" which mean root. The relationship is mutually beneficial. It forms colonies on the roots of a host plant. The fungus spreads threadlike feeding structures called hyphae into the soil. This type of colonization allows the host plant to develop a much larger root system, sometimes 100 times in length with up to 2000 times more surface area. The increased the root surface area provides more room for water and nutrients to be taken in. The fungus serves as a bridge between the host plant and available nutrients. The hyphae help to break down organic material thus helping to release nutrients to the plant. Some fungi release chemicals to inhibit other organisms that might otherwise harm the plant. They develop a soil community that supports friendly bacteria, nematodes, springtails, earthworms, etc., but inhibits herbivores and pathogens. The fungus is considered a plant, but it has no chlorophyll so can not produce its own food. In return for their hard work, the fungi obtain a steady source of food (sugar) from the host plant.

Extractions: MYCORRHIZAE Mycorrhizae is a greek word that means Root - Fungus. Over 20,000 research papers have shown that mycorrhizae are a critical ingredient to the survival of forest trees. We now know that these mycorrhizae can help urban trees in a biological way that fertilizers and other synthetic treatments can't. Mycorrhizae help the tree by tapping nutrient rich soil spaces that the tree roots cannot reach by themselves. Mycorrhizae make trees healthier and more beautiful. Root hyphae Courtesy: Dr. David Syliva, Univ. of Florida The biology of trees requires all of the basics for life. Space, sunlight, water and nutrients are all important factors for tree health. However, the uptake of water and nutrients in trees is accomplished through the trees own roots and through beneficial fungi called mycorrhizae. Virtually all trees in a natural setting form relationships with these highly beneficial organisms. The forest is a highly competitive ecosystem, and plants must endure tremendous stresses in order to survive. Trees with the most expansive root systems have thrived at the expense of those with fewer, or less efficient, roots. In the forest, the role of mycorrhizae is paramount. When naturally-occurring mycorrhizal fungi colonize a host plant root, their strands of microscopic hyphae extend outward into the soil where they function like a network of siphons to absorb additional nutrients and water.

Benefits include: Do I need to add Mycorrhizae? In today's man-made environments plants can be greatly stressed. Environments often suffer from man-made disturbances like asphalt, concrete, compaction, top soil loss, and the absence of quality organic matter. These conditions reduce the ability of the Mycorrhizal fungus to survive and thrive. The relationship between fungi and roots are important. Artificial landscapes impact the Mycorrhizae relationship. Many nursery and agricultural soils lack Mycorrhizae due to excessive and long-term uses of chemical fertilizers and pesticides. Without the Mycorrhizal fungi, plants require more water and nutrients and are more susceptible to infestations of insects and diseases than they would in their natural environments. click here to e-mail our customer service.

http://bbclabs.com/mycorrhi.htm

Extractions: VA Mycorrhizae (VAM) in Agriculture What Are VA Mycorrhizal (VAM) Fungi? VA mycorrhizae [alias: vesicular arbuscular mycorrhizal fungi (VAM) and arbuscular mycorrhizal fungi (AMF)] are beneficial fungi that penetrate and colonize the root of the plant, then send out filaments (hyphae) into the surrounding soil. The term mycorrhizae literally means " fungus-root s" and VAM is considered endomycorrhizal since it colonizes the interior of the root. How Do VAM Fungi Work? VAM fungi are associated with the plant in a mutually beneficial relationship. The VAM fungi, nestled inside the root, sends out long filaments or hyphae to explore up to 200 times the soil area available to the root alone. The hyphae literally form a bridge that connects the plant root with large areas of soil and serves as a pipeline to funnel nutrients back to the plant. In return, the plant must supply the VAM fungi with carbon for the fungal growth and energy needs. This plant-fungal relationship is an elegant association and its development is evidently regulated by several factors. The promotion of root colonization by the VAM fungi is enhanced by different soil bacteria known as

Plant microbial interactions: positive interactions in relation to crop production and utilisation A range of micro-organisms interact positively with crop plants and play a major role in crop production. For example, soil and rhizosphere micro-organisms can: mediate the generation of inorganic nutrient ions such as nitrate, ammonium and phosphate from organic and/or inorganic material. Also, some soil micro-organisms can fix significant amounts of atmospheric nitrogen which becomes available to plants while others produce plant growth substances which enhance crop growth. The population of micro-organisms in the rhizosphere can be manipulated by inoculation of seed with specific micro-organisms. This procedure can lead to increased production of cereals such as wheat and rice. Pasture, grain and tree legume crops have symbiotic nitrogen fixing

Extractions: STAND REPLACEMENT PRESCRIBED BURNING FOR FUEL REDUCTION AND REGENERATION OF TABLE MOUNTAIN COMMUNITIES IN THE SOUTHERN APPALACHIAN MOUNTAINS SRS 4104-Disturbance and Management of Southern Ecosystems Preliminary results indicate that Pisolithus tinctorius Suillus granulatus , and Cenococcum spp. are the predominant symbionts that form mycorrhizal root tips in Table Mountain pine stands. Two years after burning, seedlings growing in areas burned at medium-low and medium-high fire intensities had twice as many mycorrhizal root tips than seedlings from sites burned at high intensities (Figure 2), indicating a lasting negative impact of high-intensity prescribed fires. Laboratory results were similar, showing that mycorrhizal roots tips are less common after fungi have been exposed to temperatures over 120 o F and almost absent after exposure to temperatures up to 180 o F. These results suggest that poor formation of mycorrhizal root tips could have caused poor regeneration of Table Mountain pine in the Tallulah burn after high-intensity burning. Frequent low-intensity burning would be one means of avoiding loss of mycorrhizal fungi.

Extractions: Mycorrhizae Associated With a Root Mycorrhizae Mycorrhizae are mutualistic symbioses between fungi (usually Asco- or Basidiomycota) and plant roots. Here, the fungi become integrated into the physical structure of the root. In ectomycorrhizae, the fungus forms an external sheath which may ultimately comprise about 40% of the root-fungus association. Hyphae also penetrate the intercellular spaces of the epidermis and cortex but do not enter cells. However, fungi in endomycorrhizal interrelationships penetrate the living cells of the root, which may become filled with mycelial clusters. Plants benefit from the association because feeder roots live longer, nutrients are absorbed more efficiently, susceptibility to plant pathogens decreases, and increased tolerance to toxic materials and environmental fluctuations results. The fungi benefit in that they receive photosynthate from the plant. Updated

The Role Of Mycorrhizae In Forestry

http://www.pearson-college.uwc.ca/pearson/fungi/mycorrh.htm

Extractions: By : Chantalle Simmons, Christopher Kreuzweiser, Cindy Graves There is a group of fungi which grow associated with plant roots in a symbiotic relationship. These are called mycorrhizae fungus root. A large volume of the soil is penetrated by fine, highly branched fungal hyphae which are "extensions" of the tree's own root system. As the fungal hyphae are very absorptive, and more efficient than the plant's roots themselves, they take up mineral nutrients from the soil and then pass some of these minerals to the plant. In return, the fungi receive sugars and other nutrients from the plant's photosynthetic processes. Hence the symbiotic relationship. The most common species of mycorrhizae are known as endomycorrhizae ( endon = within ). The fungus grows in the root's outer layer and sends the highly branched hyphae inside the cell walls. Ectomycorrhizae ( ecktos = outside ) is a separate form of mycorrhizae, in which a sheath develops around the outside of the root and extend hyphae between cells of the outer layers of the roots. Mycorrhizae also contain nitrogen fixing bacteria which fix atmospheric nitrogen. Nitrogen, in a usable form is one of the plant's most important requirements. However, plants are defendant upon the activity of soil microorganisms which in corporate nitrogen through this form of nitrogen fixation. After, nitrogen fixation has occurred usable nitrogen compounds, N02 and NH3 are available for both the micro-organism and the plants.

Extractions: People have taken plants out of their natural environments to cultivate them in agricultural systems such as plantations, orchards and farms. However, we have not changed the plant's basic needs. Plants co-evolved with soil life over hundreds of millions of years. Many plant and tree species adapted to depend on some kinds of soil microlife. Soil fungi known as mycorrhizal fungi make vital contributions to plant and soil health. Mycorrhizae simply means, "root fungus," and refers to fungi which live in close association with the root systems of plants, extending out from the plant's own roots. By nurturing and, where necessary, re-introducing mycorrhizal species, we can cultivate an essential ecological connection that will benefit our crops, our environment, and our own bottom line in agriculture or forestry. Mycorrhizal fungi have evolved in association with plants, acting to greatly increase the ability of plants to take up water and certain nutrients, while often protecting associated plants from pests and diseases. They live in and around the root zone of plants, extending far out from the plant's roots with their own network of thread-like filaments known as hyphae. This greatly extends the effective surface area of the plants roots. The association with mycorrhizal fungi greatly enhances plant health in most species, and has even become essential for the survival of certain types of plants. Avocados, bamboos, bananas, cassava, coconuts, coffee, mahogany, mangoes, palms, papayas, soybeans, and sweet potatoes are just a few examples of plants that benefit from mycorrhizae.

Extractions: Many plants benefit greatly from a symbiotic relationship with soil fungi known as mycorrhizal fungi. These fungi live on and in the root systems of plants and provide nutrients to the plant in exchange for carbohydrates exuded by the plant. Mycorrhizal fungi have root-like filament systems known as hyphae with many times the surface area of the plant roots, and thereby can extract nutrients from a much larger volume of soil than the plant can by itself. Many plants are stronger and healthier with mycorrhizae than without, and less susceptible to disease and insect attacks.
