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
