Ib ectomycorrhiza (los ntawm Greek ἐκτός ektos, "sab nraum", μύκης mykes, "fungus", thiab ῥίζα rhiza, "root"; pl. ectomycorrhizas lossis ectomycorrhizae,) yog sau los ntawm E symbiotic kev sib raug zoo uas tshwm sim ntawm ib tug fungal symbiont, los yog mycobiont, thiab cov hauv paus hniav ntawm ntau hom nroj tsuag.
Tus kab mob Ectomycorrhiza yog dab tsi?
feem ntau kis tus kab mob Ericaceous mycorrhiza (Dighton thiab Coleman, 1992). Cov fungus ib txwm koom nrog kev tsim cov kab mob yogascomycete Hymenoscyphus ericaelossis nws cov anamorphs, thiab cov nyiaj tseem ceeb ntawm chitin-N tuaj yeem xa mus rau cov nroj tsuag tswv (Kerley thiab Nyeem, 1995).
Tus kab mob twg feem ntau koom nrog Endomycorrhizal koom haum?
Glomeromycota. Cov tswv cuab ntawm Glomeromycota, yog lub luag haujlwm tsim cov koom haum sib koom ua ke hu ua endomycorrhizae nrog cov hauv paus hniav txog li 70% ntawm lub ntiaj teb cov nroj tsuag. Cov endomycorrhizae no tseem hu ua arbuscular mycorrhizal fungi, abbreviated AMF.
YPuas Ectomycorrhizal yog cov kab mob fungus?
Ectomycorrhizal (ECM) fungi form mutualistic symbioses nrog ntau hom ntoothiab suav tias yog cov kab mob tseem ceeb hauv cov khoom noj thiab cov pa roj carbon monoxide hauv hav zoov ecosystems. Peb qhov kev txaus siab ntawm lawv lub luag haujlwm hauv cov txheej txheem no yog cuam tshuam los ntawm qhov tsis muaj kev nkag siab ntawm lawv cov av-yug mycelial systems.
hom kab mob twg pom nyob hauv mycorrhizae?
Mycorrhizal fungi account rau txog10% ntawm cov kab mob uas tau txheeb pom, suav nrog txhua qhov tseem ceeb ntawm Glomeromycota thiab feem ntau ntawm Ascomycota thiab Basidiomycota. Muaj ntau yam sib txawv ntawm cov koom haum mycorrhizal, suav nrog arbuscular, ericoid, orchid thiab ectomycorrhiza.
