Introduction Common characteristics all fungus share are that  their cells feature membrane-bound, complex  structures such as a nucleus, enclosed within  membrane  Pathogenic fungi are fungi that cause disease in  humans and other organisms with the uncanny  ability to spread fear amongst the general public and  concern within the medical profession

Introduction Fungus is dangerous in the way it pushes other  organisms to the brink or completely to extinction  Scientists are studying fungi to gain a better  understanding of its methods of surviving, infection  of hosts and protection mechanisms With greater understanding scientists hope to get a  handle on fungi in its beginning stages of infection,  mainly recognizing the symptoms

Evolution Fungal phylogeny was  once based on  morphological  characteristics and  heterotrophic nutrition The new classification  is based on molecular  analysis of fungal DNA  and distinguishing  fungal characteristics  http://www.springerlink.com.ezproxy2.library.drexel.edu/content/vl13

Evolution New classification is based on molecular analysis of  fungi, and finding traits from the organisms’ life  cycles, structural anatomy, and biochemical pathways Examples of fungi characters include flagellation, cell  wall structure, and the site of meiosis to determine a  modern monophyletic classification

Evolution Blastocladiomycota, the phylum containing the  Chytridmycota, the chytrid fungi, are estimated to be  the oldest fungal group in the phylogenetic tree  Blastocladiomycota are unique in that meiosis is  sporic, the result is an alternation of generations
