Upsettingly Great Mushroom in Michigan weighs 440 Tons and is 2500 Years Old


Evidence of Armillaria gallica mushroom on a scrap of wood. Picture: James B. AndersonIt's name is an unusual mushroom growth of a single genetic individual, nicknamed "genetic mushroom". An updated analysis of this gigantic mushroom monster shows that scientists at first were much older and older than they thought. This single genetic individual, known as C1, belongs to a species of fungus called Armillaria gallica known as honey fungus. When the University of Toronto biologist James B. Anderson first examined this great growth in 1992, his size was astonishing. Anderson and his colleagues estimated that they were 1,500 years old, and occupied an area of ​​100,000 kilograms (110 tons) and nearly 37 acres (15 hectares) of forest in the Upper Peninsula of Michigan. Although there are no thousands of tree roots, the C1 sample, which has been present for hundreds of years, has been declared to be among the largest and oldest organisms on earth. Almost 30 years later, and before his retirement, Anderson decided to return. Take more precise C1 measurements and see the forests have changed over the decades.

As the updated study notes, the gigantic fungus is actually closer to the age of 2,500 and weighs 400,000 kilograms or 440 tons. Growth covers about 173 acres (70 hectares) of the same size as the total floor area of ​​the Pentagon building. . I see these estimates as a lower limit, And said Anderson. Di Mushrooms could have been much older. However, we believe that we have limited all dimensions as in 1992. Or Like other mushrooms, A. gallica germinates fungi on the forest floor, but these species also use underground strips, which are underground underground. Excessive organism by searching and locking food sources. Mushrooms, as you will remember from the 4th grade science class, cannot do photosynthesis, instead they have to grow up in other living or dead organisms such as decaying plant or animal substances, and have to obtain food. The branches of the Armillaria fungi are equipped with an organ called rhizomorphs and the rhizomorphs of A. gallica can absorb nutrients from the living tree. And in fact, it is known that this species infects living trees and then continues to feed the decaying substance. Anderson says A. gallica plays a “major role in causing wood decay and root disease And. In addition to characterizing the height, weight and age of Anderson, Anderson also investigated cells that were compared to the A. reference genome. Gallica. Analysis of the cell sample on 245 showed that the DNA mutation rates in C1 were extremely low. Some mutations were observed, but did not affect the health of the fungus or its appearance. Ir What we're going to tell us is that the fungus must be a mechanism that protects itself from the mutation, And said Anderson. This mechanism allows one way to localize mutations in areas where the fungus does not cause too much damage. In this article, Anderson and his colleagues believe that this mechanism prevents harmful organisms from occurring in some parts of rhizomorphs that are responsible for maintaining the continued growth and development of the organism. Learning more about this process suggests that researchers can lead to improvements in cancer research. Olabilir It can be an interesting point of comparison, And said Anderson. , Cancer is very unstable, highly mutated and prone to genomic changes, whereas A. gallica is a very persistent organism with very few mutations. while, it is not the biggest creature in the world. This distinction goes to the personal development of Armillaria ostoyae in Eastern Oregon, covering 2,352 acres of the Malheur National Forest. This particular individual is estimated to be between 2,400 and 8,650 years of age. Or, with another measure, the largest organism, unfortunately, can now be dying, the 13 million pound clonal aspen forest in Utah.[biorxiv]Original Article can be found by clicking here.
