Ant–fungus mutualism - Wikipedia
Leafcutter ants constitue 41 species of ant across the genera Atta and Acromyrmex, Indeed, their unique relationship with a symbiotic fungus has been compared to Mutualism is typically understood to describe the interaction between two. Mutualism is also commonly referred to as a symbiotic relationship, which are Instead, they are used to grow fungus within the leaf cutter ant colony, which is. Trying to capture the movement of a colony of leaf-cutter ants in a to feed their mutualistic fungus (of the family Lepiotaceae), which acts as a.
Soldiers protect the nest; workers gather leaf material. So, they actually groom it, and clean it, and prune it," explains Currie. There is also a specialized group of ants that are the trash workers, who carry the old garden material and put it in specialized refuse dumps. A third "player" is also crucial in this symbiotic city.
Many microbes, plants and animals benefit from 'friendly' associations. Researchers describe the complex relationship between a beetle, two types of tree fungus and a bacterium that aids in their struggle to survive and thrive.
Adult beetles have a specialized compartment in their bodies used to store two other organisms: Interestingly, the antibiotic inhibits the growth of a fast-growing competitor fungus but does not affect the slow-growing beneficial fungus.
Leafcutter ants, fungi, and bacteria
Zina Deretsky, National Science Foundation Bacteria found on the bodies of the ants produce antibiotics that help maintain the health of the fungus garden. Over the years, these bacteria appear to have evolved new antibiotics to keep the gardens healthy.
This co-evolution could help researchers create new antibiotics for humans. Energy experts Leaf-cutter ants are also adept teachers in energy research.
Figuring out how the ants do it could lead to cleaner replacements for petroleum. Donohue says the success of this renewable energy work could also provide farmers and foresters with a second revenue stream from their agricultural products; essentially another income from what is now a waste product. Fungus can only grow if it is free from pests, which means the leaf ants must constantly tend their garden to prevent these fungi pests from spreading.
On the skin of leaf ants live bacteria whose only purpose is preventing fungi pests.
Leaf ants and the bacteria on their skin are also involved in mutualism because the bacteria are allowed to live on the ants in exchange for helping the ants care for their fungus garden. Now that you know the basics of leaf cutter ants mutualism, we can dive into this subject in greater detail. During mating season, a young leaf ant queen will set out to start a new colony.

In order to do so, she takes a small amount of fungus from her old colony. The queen will lay her eggs and build a chamber for the fungus.
Leaf Cutter Ants
Once the eggs hatch, the new worker ants will be responsible for tending to the fungus to support mutualism. Until that time occurs, the queen will take care of the fungus. Leaf cutter ants are considered social insects, which means different ants serve different roles within the colony. Some ants will forage for leaves, others will take care of the fungus garden, and some will be responsible for defending the colony.
Preventing Contamination Because leaf ants and the fungus that they tend to and eat are so dependent on each other, both are especially vulnerable to harm.
For instance, both can be killed by a variety of microbes, many of which can be found on the leaves that the ants and the fungus need to survive. Fortunately, their symbiotic relationship works to protect each species from harm. First, fungus has the natural ability to protect itself from microbes by producing antibiotics, which can also protect ants when they eat the fungus.
Second, when ants grow their garden, they are very careful about cleaning both themselves and the fungus.
In addition to weeding their gardens, many leaf ant colonies have a dedicated waste storage chamber, which serves to further protect the garden. The fecal matter of leaf ants also contains several chemicals that can suppress pests and promote fungal growth. As you can see, the relationship between ants and fungus gardens helps to protect both, which is the essence of mutualism.
Antimicrobials and Ants In a previous section, we briefly touched on the fact that certain types of bacteria can live on the skin of leaf ants. Examining this issue in a little more detail can help you better understand how mutualism works. These bacteria are very interesting in that their antifungal properties will attack pests while leaving the fungus in the garden unharmed.
