The fungus kingdom encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from unicellular aquatic chytrids to large mushrooms. However, little is known of the true biodiversity of the fungus kingdom, which has been estimated at 2.2 million to 3.8 million species. [ 7 ]
Rust fungi are often categorized by their life cycle. Three basic types of life cycles are recognized based on the number of spore types as macrocyclic, demicyclic, and microcyclic. [3] The macrocyclic life cycle has all spore states, the demicyclic lacks the uredinial state, and the microcyclic cycle lacks the basidial, pycnial, and the aecial ...
Entomopathogenic fungi show a diversity of lifecycles, with differences across lineages, as well as within lineages, between species, and even between isolates within species. [5] Some fungal entomopathogens are opportunistic whereas some have evolved into highly specific pathogens of insects. [1]
Some time after the Permian-Triassic extinction event (251.4 Ma), a fungal spike (originally thought to be an extraordinary abundance of fungal spores in sediments) formed, suggesting that fungi were the dominant life form at this time, representing nearly 100% of the available fossil record for this period. [33]
The 1995 edition of the influential Ainsworth and Bisby’s Dictionary of the Fungi sought to replace the term anamorph with mitosporic fungus and teleomorph with meiosporic fungus, based on the idea that the fundamental distinction is whether mitosis or meiosis preceded sporulation. This is a controversial choice because it is not clear that ...
Mold had been used as a common name for now non-fungal groups such as water molds or slime molds that were once considered fungi. [ 6 ] [ 7 ] [ 8 ] Molds cause biodegradation of natural materials, which can be unwanted when it becomes food spoilage or damage to property.
After two weeks of being infected by the fungus, the plant no longer generates the sugary liquid, and the fungus produces sclerotia. The sclerotium is an overwinter structure, which contains ergot alkaloids. Claviceps purpurea ' s life cycle is an interesting model for plant pathologists and cell biologists because: [4] Strict organ specificity ...
Roles of fungi in the marine carbon cycle by processing phytoplankton-derived organic matter. Parasitic fungi, as well as saprotrophic fungi, directly assimilate phytoplankton organic carbon. By releasing zoospores , the fungi bridge the trophic linkage to zooplankton , known as the mycoloop.
