Study Notes
Fungal Diversity and Ecology
- Lignin, a complex polymer in woody plants along with cellulose, provides rigidity and is decomposed mainly by wood-rotting fungi, such as brown rot and white rot fungi.
- Most fungi are multicellular, forming hyphae and asexual spores, and some grow as single cells known as yeasts.
- Fungal cell walls consist of chitin, with other polysaccharides and small amounts of proteins, lipids, polyphosphates, and inorganic ions.
- Some fungi form mycorrhizal associations with plant roots to facilitate mineral uptake, while others form lichens with cyanobacteria or green algae.
- Fungal pathogens cause widespread crop and plant damage, as well as human fungal diseases, ranging from minor to life-threatening conditions.
- Mucoromycota and Glomeromycota are two groups of fungi, with Mucoromycota commonly found in soil and on decaying plant material, and Glomeromycota forming symbiotic relationships with plant roots.
- Rhizopus nigricans, a common black bread mold, undergoes a complex life cycle involving both asexual and sexual reproduction, forming haploid spores and diploid zygospores.
- The white rot fungi play a key role in decomposing woody materials in forests, making them of major ecological importance.
- Fungal hyphae typically grow together across and above a surface to form a compact mycelium, from which aerial hyphae reach up into the air above the surface, and spores called conidia are formed on their tips.
- Fungal plant pathogens cause significant yearly losses in fruit and grain crops, and human fungal diseases range from minor conditions to serious systemic mycoses.
- Ectomycorrhizae typically forms between basidiomycetes and the roots of woody plants, while endomycorrhizae forms between glomeromycete fungi and many nonwoody plants.
- Some fungi also form associations with cyanobacteria or green algae, known as lichens, and can invade and cause disease in plants and animals.
