BLG 144 Lecture Notes - Lecture 1: Lignin Peroxidase, Pathogenic Fungus, Hypha
Document Summary
Evidence that fungi are closely related to animals: both synthesize chitin, dna sequence data, fungal flagella, both store glucose as glycogen. Primary food of many animals (moose caribou eat lichen) d. iii) Initiate soil production in barren areas: non-lichen formers are found in virtually every terrestrial habitat, as well as some freshwater and marine environments e. i) many are single-celled yeasts e. ii) Some form emf associations with tree roots e. iii) Ascus-bearing cup- or saucer-shaped reproductive structure, called an ascocarp e. iv) most common fungal endophytes e. v) Used often to clean up contamination; this group also includes fungus to make penicillin, as well as yeast and the valuable foods truffles and morels. Lichen can be classified as: nitrogen-sensitive (ex: usnea, evernia, hypogymnia, nitrogen-loving (ex: leafy xanthoria, cushion xanthoria, physcia) a) (shows a lot of acid rain in that area) Soredia: spore which contain algal cell wrapped by a fungal hyphae. Chytrids and zygomycetes are paraphyletic and are poorly resolved.
