Mycology Definition
Mycology is the study of fungi, their relationships to each other and other organisms, and the unique biochemistry which sets them apart from other groups. Fungi are eukaryotic organism which belong to their own kingdom. Until advances in DNA technology, it was assumed that fungi were an offshoot of the plant kingdom. DNA and biochemical analysis has revealed that fungi are a separate lineage of eukaryotes, distinguished by their unique cell wall made of chitin and glucans which often surrounds multinucleated cells. Mycology is a necessary branch of biology because fungi is considerably different from both plants and animals.
History of Mycology
Until the 1800’s, it was assumed that fungi were simply a different kind of plant. Mushrooms, the reproductive bodies of fungi, were eaten, used as medicine, and used for their hallucinogenic effects since antiquity. Many classic Greek philosophers and naturalists considered fungi, but still assumed they were more related to plants. By the mid-1800’s the microscope was invented, and scientists began to examine the inner workings of fungi. Microscopes revealed that fungi had distinct features, separate from both plants and animal cells. The term mycology was coined in 1836 in a paper by M.J. Berkeley, when fungi were beginning to be recognized as their own unique kingdom.
However, it was not until the advent of modern biochemistry and DNA analysis that it was fully realized how different fungi were. Instead of a cell wall made of cellulose, the wall in fungi is composed of glucans and chitin, molecules found in plants and insects, respectively. Instead of having a single nucleus, like most plants and animals, fungi are often multinucleated and contain special pores allowing the cytoplasm and nucleus to flow freely between various chambers in the fungal organism. DNA analysis revealed a closer relation to animals than plants. As scientists observed fungal lifecycles further, they realize that the majority of most fungi spends its time as a mold or ooze. This multicellular lifeform moves its way through decaying organic material, utilizing the minerals and organic molecules as it goes. Not only was fungi the major decomposing organism in the world, scientist also determined that certain fungi were responsible for events like fermentation and crop diseases.
With this, the field of mycology exploded. Agricultural mycology focuses on utilizing and controlling fungi in commercial crops. Toxicologists study mushroom and fungi for compounds which adversely affect other organisms. Pharmaceutical companies race to extract useful compounds from mushrooms. Careers in mycology are as diverse and complex as the field itself.
Careers in Mycology
Mycology first became an important science in the agricultural industry, and remains so today. A phytopathologist studies plant diseases, especially those which affect crops. Fungi are a major pest for many crops, but also serve symbiotic roles and allow plants to extract nutrients and water from the soil. Mycology is needed to distinguish between beneficial and harmful fungi, as well as to treat crops and prevent future infections. Further, certain types of fungi are used as pesticides, as they are more natural than synthetic pesticides and can kill targeted insects.
