Chytridiоmycоtа аnd Relаtives: Fungi with ZоosporesThe Chytridiomycota are closely related to ancestral fungi.Chytrids produce flagellated asexual spores called zoospores and are common in aquatic environments and soils, with several species pathogenic in plants, algae, and amphibians. The chytrid B. dendrobatidis may be responsible for a global reduction in amphibian populations.Blastocladiomycetes exhibit an alternation of generations.Blastocladiomycetes, also known as blastoclads, are found in both aquatic and terrestrial environments. They are parasites of plants, invertebrates, algae, and in one case, other fungi. Possibly the most distinguishing feature of blastocladiomycetes is a haplodiplontic life cycle where there is alternation between haploid and diploid generations in multicellular forms of the organism. Given the ease with which some blastoclads can be grown in culture, they are sometimes used in teaching laboratories to demonstrate the alternation of generations seen in some plant reproductive cycles.Neocallimastigomycetes anaerobically digest cellulose in ruminant herbivores.Members of the Neocallimastigomycota are found in the guts of ruminants, where they digest cellulose and lignin, making valuable nutrients available to the animals. Organisms in the genus Neocallimastix can survive on cellulose alone. Genes encoding digestive enzymes such as cellulase made their way into the Neocallimastix genomes via horizontal gene transfer from bacteria. Due to the anaerobic growth of these fungi and their abilities to degrade cellulose at relatively high temperatures, they have potential uses in biotechnology for biofuel production.
