Fungi tseem ceeb heev rau cog lub neej ob leeg ua khub thiab ua yeeb ncuab. Lawv yog cov khoom tseem ceeb ntawm kev noj qab haus huv vaj ecosystems, qhov chaw uas lawv rhuav tshem cov organic teeb meem, pab tsim av, thiab tsim kev koom tes nrog cov hauv paus hniav.

Feem ntau ntawm cov fungi yog microscopic. Qee hom tsim cov hlua ntawm cov hlwb hu ua hyphae, uas yog lawv tus kheej nqaim dhau lawm; lwm tus, hu ua poov xab, loj hlob raws li ib leeg hlwb. Fungal hyphae taug kev tsis pom los ntawm cov av thiab colonize cov khoom noj. Txawm li cas los xij, ntau hom fungal siv hyphae los tsim cov qauv loj dua uas koj tuaj yeem pom hauv koj lub vaj lossis vaj. Txawm tias nceb muaj ntau hyphae nyob ze ua ke. Peb txhua tus tau pom cov nceb, tab sis cov neeg saib xyuas yuav tuaj yeem txheeb xyuas lwm cov kab mob fungal, rhizomorph.

Rhizomorphs yog dab tsi?

Ib rhizomorph yog ib txoj hlua zoo li sib sau ua ke ntawm ntau hyphal strands. Lo lus "rhizomorph" txhais tau tias "hauv paus daim ntawv". Rhizomorphs muaj npe vim tias lawv zoo li cov cag ntoo.

Rhizomorphs nyob rau hauv lub tiaj nraum qaum tsev los yog hav zoov yog ib tug kos npe rau ntawm ib tug vibrant fungal zej zog. Tej zaum koj yuav tau pom lawv nyob hauv av, hauv qab cov ntoo uas tuag lawm, los yog qhwv ib ncig ntawm cov stumps.

Rhizomorphs Zoolos yog phem?

Cov fungi uas tsim rhizomorphs tuaj yeem yog cov phooj ywg cog, cog cov yeeb ncuab, lossis cov neeg tsis sib haum xeeb. Nrhiav ib lub rhizomorph hauv koj lub vaj tsis tas yuav zoo lossis phem hauv nws tus kheej. Txhua yam nyob ntawm seb hom kab mob fungal twg yog qhov chaw ntawm rhizomorph thiab seb cov nroj tsuag nyob ze puas noj qab haus huv lossis mob.

Ib tug yeeb ncuab cog uas tsim rhizomorphs yog bootlace fungus (Armillaria mellea). Hom Armillaria no yog ib qho tseem ceeb ntawm cov hauv paus rot uas feem ntau tua cov ntoo thiab tsob ntoo. Nws tuaj yeem kis tau cov ntoo noj qab haus huv yav dhau los ntawm cov kab mob raug mob, lossis nws tuaj yeem tua cov kab mob uas twb muaj lawm ntawm lwm hom ntoo. Cov rhizomorphs dub los yog xim liab-xim av ntawm cov tsiaj no loj hlob hauv qab tsob ntoo uas muaj kab mob thiab hauv cov av ib puag ncig. Lawv zoo li bootlaces thiab tuaj yeem ncav cuag li 0.2 nti (5 mm.) inch. Yog tias koj pom ib qho ntawm cov rhizomorphs ntawm tsob ntoo, tsob ntoo muaj kab mob thiab tej zaum yuav tau muab tshem tawm.

Lwm cov rhizomorph-forming fungi yog saprophytes, txhais tau tias lawv nyob ntawm decomposing organic khoom xws li poob nplooj thiab cav. Lawv tau txais txiaj ntsig tsis ncaj rau cov nroj tsuag los ntawm kev tsim cov av thiab ua lub luag haujlwm tseem ceeb hauv cov zaub mov hauv av.

Qee mycorrhizal fungi form rhizomorphs. Mycorrhizae yog symbiotic alliances ntawm cov nroj tsuag thiab fungi nyob rau hauv uas cov fungus xa dej thiab as-ham absorbed los ntawm cov av mus rau cov nroj tsuag nyob rau hauv sib pauv rau carbohydrates uas cov nroj tsuag tsim. Ntev-ntev rhizomorphs pab tus khub fungal nqa dej thiab cov as-ham los ntawm cov av ntau dua li cov nroj tsuag cov hauv paus hniav tuaj yeem tshawb pom ntawm lawv tus kheej. Cov txiaj ntsig norhizomorphs yog cov khoom noj tseem ceeb rau ntau hom ntoo.

Rhizomorphs Ua dab tsi?

Rau cov kab mob, cov rhizomorph lub luag haujlwm suav nrog kev tawm mus nrhiav cov khoom noj ntxiv thiab thauj cov as-ham mus ntev. Rhizomorphs ntawm fungi tuaj yeem mus deb tshaj li tus neeg hyphae tuaj yeem. Qee cov rhizomorphs muaj qhov chaw khoob zoo ib yam li cov nroj tsuag xylem, uas tso cai rau cov fungus thauj cov dej ntim ntau dua thiab cov khoom noj uas muaj dej-soluble.

Rhizomorph-forming mycorrhizal fungi siv cov qauv no los nrhiav cov ntoo tshiab los koom tes nrog. Cov bootlace fungus siv nws cov rhizomorphs taug kev los ntawm cov av thiab ncav cuag cov ntoo tshiab kom kis tau. Nov yog qhov fungus kis los ntawm hav zoov ntawm cov ntoo raug mob.

Tom ntej no koj pom cov hauv paus zoo li cov hlua hauv koj lub vaj av lossis loj hlob ntawm lub cav poob, xav txog cov ntaub ntawv rhizomorph hauv kab lus no thiab xav tias lawv yuav tsis yog cov hauv paus tab sis ib qho kev tshwm sim ntawm lub ntiaj teb feem ntau pom tsis pom fungal..
