Document Summary
Arbuscular mycorrhizae (endomycorrhizae) glomeromycota: form monophyletic group, hyphae grow inside cells when attached to plant roots. Ectomycorrhizae: formed in both ascomycota and basidiomycota, coat outside of roots, extend root surface, provide water, decompose, external mantle of hyphae on fine roots, endomychorrhizal symbiosis evolved multiple times. Dikarya: basidiomycota (club fungi, mushrooms/toadstools, wheat rust, bracket fungi, basidium: the base or pedestal on which spores are borne (cid:498)basidiocarps of basidiomycota(cid:499) or (cid:498)fruiting bodies with basidia(cid:499) Dikaryotic for most of life cycle so they don"t have to look for a. In club fungi, the products of meiosis are borne on the surface of the gills on specialized hyphal tips called basidia. Fruiting bodies consist solely of dikaryotic hyphae, and the dikaryotic phase can last a long time: more successful than ascomycota mating partner. Nuclei are proliferated by mitosis and recombination occurs during meiosis (importance of sexual reproduction: one mating event leads to multiple recombination events.
