Close Search. Nutrient Efficiency. How Mycorrhizae Increase Nutrient Efficiency. The mycorrhizal symbiosis can increase the production of solubilizing enzymes by the plants themselves, also helping to make tightly bound nutrients accessible. Mycorrhizae also work together with other soil microorganisms, which help the fungus extract more nutrients for the plant.

Research confirms that mycorrhizae are particularly important in mobilizing phosphorus, nitrogen, zinc, iron, calcium, magnesium, manganese, sulfur and other important soil nutrients by enzymatic release from tightly held chemical bonds and transporting them back to the plant. Mycorrhizal fungi reduce nutrient runoff The additional absorptive surface area provided by mycorrhizal mycelium ensure that more of the nutrients from fertilizers are absorbed and utilized, reducing the amount that is wasted via runoff.

Not only does this avoid the financial waste of these inputs running off into the ground water rather than being utilized by the plant, this also has an ecological benefit, reducing the negative impact that this nutrient runoff can have on waterways and groundwater.

Mycorrhizae can mitigate negative effects of over fertilization Through the buffering effect that mycorrhizal provide, which protect plants from toxic conditions, heavy metals, salts, etc. How it Works Links Overview Technical Resources Mycorrhizae FAQs Research Recent News.

Nitrogen and phosphorus are among the elements considered most limiting to plant growth and productivity because they are often present in small quantities locally or are present in a form that cannot be used by the plant. As a result, the evolution of many plant species has included the development of mutually beneficial symbiotic relationships with soil-borne microorganisms.

In these relationships, both the host plant and the microorganism symbiont derive valuable resources that they need for their own productivity and survival as a result of the association.

Nitrogen Fixation. Despite the fact that nitrogen is the most abundant gaseous element in the atmosphere, plants are unable to utilize the element in this form N 2 and may experience nitrogen deficiency in some soils that have low nitrogen content.

Since nitrogen is a primary component of both proteins and nucleic acids, nitrogen deficiency imposes significant limitations to plant productivity. In an agricultural setting, nitrogen deficiency can be combated by the addition of nitrogen-rich fertilizers to increase the availability of nutrients and thereby increase crop yield.

However, this can be a dangerous practice since excess nutrients generally end up in ground water, leading to eutrophication and subsequent oxygen deprivation of connected aquatic ecosystems. Plants are able to directly acquire nitrate and ammonium from the soil.

However, when these nitrogen sources are not available, certain species of plants from the family Fabaceae legumes initiate symbiotic relationships with a group of nitrogen fixing bacteria called Rhizobia.

These interactions are relatively specific and require that the host plant and the microbe recognize each other using chemical signals. The interaction begins when the plant releases compounds called flavanoids into the soil that attract the bacteria to the root Figure 4.

In response, the bacteria release compounds called Nod Factors NF that cause local changes in the structure of the root and root hairs. Specifically, the root hair curls sharply to envelop the bacteria in a small pocket. The plant cell wall is broken down and the plant cell membrane invaginates and forms a tunnel called an infection thread that grows to the cells of the root cortex.

The bacteria become wrapped in a plant derived membrane as they differentiate into structures called bacteroids. These structures are allowed to enter the cytoplasm of cortical cells where they convert atmospheric nitrogen to ammonia, a form that can be used by the plants.

Mycorrhizal interactions with plants. In addition to symbiotic relationships with bacteria, plants can participate in symbiotic associations with fungal organisms as well. There are several classes of mycorrhiza, differing in structural morphology, the method of colonizing plant tissue, and the host plants colonized.

However, there are two main classes that are generally regarded as the most common and therefore, the most ecologically significant. The endomycorrhizae are those fungi that establish associations with host plants by penetrating the cell wall of cortical cells in the plant roots.

By contrast, ectomycorrizae develop a vast hyphae network between cortical cells but do not actually penetrate the cells. The most common endomycorrhizal interaction occurs between arbuscular mycorrhizal fungi AMF; also called Vesicular-Arbuscular Mycorrhiza or VAM and a variety of species of grasses, herbs, trees and shrubs.

When phosphate is available in the soil, plants are able to acquire it directly via root phosphate transporters. However, under low phosphate conditions, plants become reliant on interactions with mycorrhizal fungi for phosphorus acquisition.

Mycorrhizal spores present in the soil are germinated by compounds released from the plant. Hyphae extend from the germinating spore and penetrate the epidermis of the plant root. Inside the root, the hyphae branch and penetrate cortical cells, where highly branched structures called arbuscules develop Figure 5.

Growth factors stimulate anabolic metabolism by directing nutrient uptake It appears that these presumably unwelcomed microbes dominated in the relationships under the examined conditions; alternatively, the observations may indicate compromises for unidentified benefits in the plants.

Farmers invest significant resources in purchasing and applying fertilizers, only to witness considerable portions of these investments literally flowing away. For instance, colonization of AM fungi significantly increased the transcript level of LePT4, a phosphate transporter in tomato plants, with a concomitant 2-fold increase in phosphate uptake; meanwhile a loss-of-function mutation in LePT4 significantly impaired the AM fungi-enhanced phosphate uptake Xu et al.
