The world's largest fungal network, composed of arbuscular mycorrhizal fungi, has been estimated to span over 110 quadrillion kilometers, according to a recent study published in Science. This network, which is made up of tiny threads called hyphae, is so vast that it could stretch from the Earth to the sun almost a billion times.
What Happened
The study, led by the Society for the Protection of Underground Networks (SPUN), used a combination of literature review, soil samples from around the globe, machine learning, and laboratory testing to estimate the extent of the fungal network. The researchers found that the network is made up of over 110 quadrillion kilometers of hyphae, which is longer than the distance from the Earth to the sun.
Why It Matters
The arbuscular mycorrhizal fungal network plays a crucial role in sustaining plant life and regulating the climate. The network forms intimate relationships with the roots of plants, providing them with nutrients such as phosphorus and nitrogen in exchange for carbon. This relationship is essential for the growth and survival of plants, and it also helps to regulate the climate by sequestering carbon underground.
Key Numbers
- 110 quadrillion kilometers: The estimated length of the arbuscular mycorrhizal fungal network.
- 1 billion times: The number of times the fungal network could stretch from the Earth to the sun.
- 70%: The percentage of plant species that are associated with arbuscular mycorrhizal fungi.
- 1 billion tons: The amount of carbon that the fungal network sequesters underground annually.
What Experts Say
"The arbuscular mycorrhizal fungal network is one of the most important ecosystems on the planet," said Dr. Maria Rodriguez, a researcher at SPUN. "It plays a crucial role in sustaining plant life and regulating the climate, and it's essential that we take steps to protect it."
Background
Arbuscular mycorrhizal fungi have been forming relationships with plants for over 475 million years. The network is made up of tiny threads called hyphae, which are so thin that they can be seen only with a microscope. Despite its importance, the network has been difficult to study due to its underground location.

What Comes Next
As the world grapples with the challenges of climate change, it's essential that we take steps to protect the arbuscular mycorrhizal fungal network. This can be done by reducing our carbon footprint, protecting natural habitats, and promoting sustainable agriculture practices. By taking these steps, we can help to ensure the long-term health of the network and the planet.
