Site dedicated to the taxonomy of Ascomycota. Vanderbilt University. A bird’s beak or a whale’s flipper contains information not only its function but also about its history.
Similarly, information stored in DNA includes not only instructions about a cell’s function or the transformation of an egg into an embryo, but also a record of the organism’s biological past, and its history of change and adaptation. Far from the prevailing notion of the genome as a “blueprint”, the DNA of any organism more likely resembles a continually edited palimpsest, assembled over 3.5 billion years, whose sequence of letters contains important clues to major organism features that are largely yet to be deciphered.
In the Rokas lab, we study the DNA record to gain insight into the patterns and processes of evolution, focusing on three major questions: Partial mycoheterotrophs: The green plants that feed on fungi. You probably learned this basic lesson of biology in elementary school: Plants are self-feeders.
These so-called autotrophs use the sun’s energy and water to turn carbon dioxide from the air into food through the process known as photosynthesis. Autotrophic organisms sit at the base of every food chain on Earth and sustain all levels of life as we know it. But competition among plants for resources like water, light and nutrients can be intense. Stinkhorns, truffles, smuts: The amazing diversity – and possible decline – of mushrooms and other fungi.

Viewable. The Global Fungal Red List Initiative. Species of fungi are threatened by habitat loss, loss of symbiotic hosts, pollution, over exploitation, and climate change, but the vast majority of fungal species have not been assessed. The aim of the global IUCN Red List of Threatened Species™ is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community reduce species decline and extinction.
The IUCN Red List is widely recognized as the most comprehensive, objective global approach for evaluating the conservation status of animal, fungal and plant species, and it has a large impact on the setting of priorities in nature conservation. How can I contribute? Nominations are encouraged from anyone who can provide information on fungal species that are likely to be globally threatened and therefore should be evaluated.
