Fungi and Plants/Animals Flashcards
Symbiosis
Close long-term biological relationship between two organisms
Biotrophs
Pathogens that obtain nutrients and energy from a living host
Model biotroph
Ustilago maydis (corn smut)
Teliospores
Thick-walled resting spores formed by corn smut
Specialized structure used to penetrate plant cells
Appressorium
Haustorium
Feeding structure containing receptors and transport proteins to absorb nutrients from cell
Necrotrophs
Pathogens that kill and obtain energy from a dead host
Model necrotroph
Black spot disease
Hemibiotrophs
Fungal pathogens with an initial biotrophic phase that shift to necrotrophic once infection well-established
Highly conserved molecules present and essential in microbes but absent from plants
Microbe-Associated Molecular Patterns
Surface-localized transmembrane proteins that recognize MAMPs and transmit alarm signal
Pattern Recognition Receptors
Hartig net
Fungal growth between root cells found in ectomycorrhiza
Dense fungal mycelium that coats root in ectomycorrhiza
Mantle
Arbuscule
Fungal growth within plant cells, site of nutrient exchange
Specialized hyphal extension for attachment and penetration in AMF
Hyphopodium
Model ectomycorrhiza
Laccaria bicolor
Hormone secreted by plant roots under N or P deprivation
Strigolactone
Perifungal membrane
Extension of plant cell membrane surrounding hypha
Peri-arbuscular membrane
Extension of plant cell membrane surrounding arbuscules
Nutrient-rich hyphal swelling used as ant food
Gonglydia
Ruminants
Hoofed herbivores that can acquire nutrients from plant-based foods
Generalists
Infect and consume insect host rapidly, not host specific, necrotrophic
Specialists
Infect specific host, often affecting behaviour/morphology, use host for food and spore dispersal, hemibiotrophic
Fungal disease in humans
Mycosis
Aspergillosis
Disease of lungs caused by inhaling conidia/spores of Aspergillus fumigatus
