Document Summary
* chytrids are swimmers depends on having free water in their environment; live in lakes and soil. * in soil there is film of water surrounding soil particles when the film is moist; when the soil is dry, chytrids don"t live there. * synchytrium endobioticum lives in potatoes and causes potato wart disease and is very serious if you"re a potato grower because you can"t sell the potatoes anywhere. * treated as an order of the zygomycetes before, but now they"ve gone from order to phylum. * they"ve been around since the origin of land plants (+400 mil years) * may be essential for colonization of land plants. * all of them form symbioses with photosynthetic autotrophs (photoautotrophs); most form mycorrhizae with vascular plants called endomycorrhizae (or arbuscular mycorrhizae) * they deliver nutrients with hyphae to roots of plants, which exchanges sugars from ps. * they grow in the ground filamentously, and produce spores so can"t see them aboveground.
