Fungal-bacterial endosymbiosis encompasses the mutualistic relationship between a fungus and intracellular bacteria species residing within the fungus. Highly complex interactions among roots, fungi and bacteria underlie the Credit: Ectomycorrhizal Fungi image by Dr. Hugues Massicotte, Forest suggest that a more intricate symbiosis of microbial life underpins willows'. Hyphae and asexual sporangia of Rhizopus microsporus (photo by Stephen Understanding how fungal-bacterial interactions influence lipid.

Through mycorrhization, the plant obtains phosphate and other minerals, such as zinc and copper, from the soil. The fungus obtains nutrients, such as sugars, from the plant root.

Synergistic Relationship between plants, fungi, and bacteria

Mycorrhizae help increase the surface area of the plant root system because hyphae, which are narrow, can spread beyond the nutrient depletion zone. Hyphae are long extensions of the fungus, which can grow into small soil pores that allow access to phosphorus otherwise unavailable to the plant.

The beneficial effect on the plant is best observed in poor soils. The benefit to fungi is that they can obtain up to 20 percent of the total carbon accessed by plants. Mycorrhizae function as a physical barrier to pathogens.

They also provides an induction of generalized host defense mechanisms, which sometimes involves the production of antibiotic compounds by the fungi. Fungi have also been found to have a protective role for plants rooted in soils with high metal concentrations, such as acidic and contaminated soils.

Hyphae proliferate within the mycorrhizae, which appears as off-white fuzz in this image. These hyphae greatly increase the surface area of the plant root, allowing it to reach areas that are not depleted of nutrients. There are two types of mycorrhizae: Ectomycorrhizae form an extensive dense sheath around the roots, called a mantle. Hyphae from the fungi extend from the mantle into the soil, which increases the surface area for water and mineral absorption.

Within the fungi, N. They have been observed replicating within vacuoles and have been found in all stages of the life of the fungus including the spores, vegetative hyphae, and plant cell-associated hyphae.

It is thought that the bacteria are transmitted vertically from parent to offspring in the fungi as permanent residents. Thus, bacterial endosymbionts are typically incorporated into growing fungi either through phagocytosis during some point in the life cycle of the fungus or passed on vertically forming permanent associations with the fungus. Benefits and metabolism[ edit ] In most cases, bacteria provide the fungus with some form of metabolic benefit while the fungus often provides a suitable living environment.

The bacteria also appears to play a role in dictating asexual spore formation in R. The benefit gained by the bacteria in this case is not specifically known.

In other cases such as N. The AM fungi host relies on the plant host for its nutrients. Interactions between bacteria and fungi are based on benefits to metabolism and represent complex interactions between bacterial, fungal and plant components.

Applications and significance[ edit ] Many of the fungal partners involved in the endosymbiotic relationship with the bacteria are also in mutualistic or parasitic relationships with other plants. The presence of intracellular bacteria living within these fungi add another level of complexity and suggests that at some level, the plant is benefitting indirectly from the interaction between fungi and bacteria.

These interactions increase nutrient availability in the plant and lead to increased plant growth and environmental stress-resistance. There exists a current demand in agriculture to cultivate and optimize to increase yield sustainably. Without considering the bacteria that live within AM fungi, like Ca. On the other side of the spectrum are the fungi that cause disease in agricultural crops leading to huge loses, such as R.
