Qhov sib txawv tseem ceeb ntawm thawj thiab theem nrab mycelium yog thawj mycelium tsim los ntawm cov kab mob fungal thaum lawv loj tuaj thiab tsim cov kab mob thaum cov ntaub ntawv thib ob mycelium los ntawm kev sib deev hyphae thaum lawv sib txuas thaum sib deev.
Basidiomycetes yog ib pawg loj ntawm cov kab mob. Lub mycelium ntawm basidiomycete fungi tau dhau los ua ntau yam kev hloov pauv xws li theem pib, theem nrab thiab theem nrab. Primary mycelium tshwm nyob rau hauv thawj theem thaum theem nrab mycelium tshwm nyob rau theem nrab ntawm lawv lub neej voj voog. Thawj mycelium tsim los ntawm basidiospores. Spores paub tab thiab tsim ag erm raj thiab tsim mus rau hauv thawj mycelium. Thaum muaj kev sib deev, kev sib deev tau sib deev ob hom hyphae sib txuas nrog ib leeg thiab tsim cov mycelium thib ob.
Primary Mycelium yog dab tsi?
Y Primary mycelium yog cov sau ntawm hyphae tsim los ntawm kev loj hlob ntawm haploid basidiospores. Yog li ntawd, thawj mycelium yog tsim tom qab germination ntawm basidiospores ntawm basidiomycetes.
Daim duab 01: Basidiospore Germination
YPrimary mycelium muaj monokaryotic hyphae. Yog li ntawd, mycelium muaj ib tug haploid nucleus. Thawj mycelium sawv cev rau theem monokaryotic ntawm lub neej voj voog. Hyphae ntawm thawj mycelia tuaj yeem sib txuas thiab tsim cov mycelium thib ob. Hauv lwm lo lus, mycelia ntawm kev sib raug zoo mating hom tuaj yeem ua ke thiab tsim cov mycelium theem nrab. Txawm li cas los xij, tsis zoo li cov mycelium thib ob, thawj mycelium tsis muaj qhov txuas txuas. Ntxiv mus, lub neej ncua ntawm thawj mycelium yog luv.
Secondary Mycelium yog dab tsi?
Secondary mycelium yog mycelium uas tsim tom qab kev sib txuas ntawm ob qho kev sib deev thawj hyphae ntawm basidiomycete fungi. Kev sib deev sib xws hyphae yog lub npe hu ua ntxiv thiab rho tawm mating hom mycelia.
Daim duab 02: Basidiomycete Lub Neej Cycle
Secondary mycelium muaj ob lub nuclei haploid, ib qho los ntawm txhua tus niam txiv. Yog li ntawd, theem nrab mycelium sawv cev rau theem dikaryotic ntawm lub voj voog nyob ntawm cov fungus. Lub dikaryotic theem tsis yog diploid. Ob tug nuclei nyob twj ywm unfused kom txog rau thaum tsis ntev ua ntej spore ntau lawm. Qhov theem dikaryotic no yog theem tseem ceeb ntawm lub neej basidiomycete. Secondary mycelium generates ib tug basidiocarp los yog fruiting lub cev uas peb hu ua nceb. Basidiocarp muaj basidia ntawm cov gills hauv qab nws lub hau.
Dab tsi yog qhov zoo sib xws ntawm Lub Tsev Kawm Ntawv Qib Siab thiab theem nrab Mycelium?
- Primary thiab secondary mycelia yog ob hom mycelia pom hauv fungi.
- Lawv yog ob txoj kev hloov pauv hauv lub neej.
- Thaum ob tus thawj mycelia conjugate, theem nrab mycelium yog tsim.
- Basidiomycetes fungi tsim ob qho tib si thawj thiab theem nrab mycelia.
Qhov txawv ntawm Thawj thiab Thib Ob Mycelium yog dab tsi?
Primary mycelium yog tsim los ntawm germination ntawm basidiospores thaum theem nrab mycelium yog tsim los ntawm kev sib txuas ntawm ob hom kev sib tw ntawm thawj mycelia. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm thawj thiab theem nrab mycelium. Tsis tas li ntawd, thawj mycelium muaj ib lub nucleus haploid. Li no, nws sawv cev rau theem monokaryotic ntawm lub neej voj voog. Nyob rau hauv sib piv, theem nrab mycelium muaj ob haploid nuclei ib tug los ntawm txhua tus niam txiv. Nws sawv cev rau theem dikaryotic ntawm lub neej voj voog. Ntxiv mus, nws yog qhov tseem ceeb ntawm lub neej voj voog.
Cov hauv qab no infographic tabulates ntau qhov sib txawv ntawm thawj thiab theem nrab mycelium.
Summary – Thawj vs Secondary Mycelium
Y Primary mycelium yog lub haploid lossis monokaryotic hyphae tsim los ntawm kev loj hlob ntawm basidiospores. Secondary mycelium yog dikaryotic hyphae tsim los ntawm kev sib txuas ntawm ob hom fungi thaum lub sij hawm kev sib deev. Yog li ntawd, thawj mycelium muaj ib tug haploid nucleus thaum theem nrab mycelium muaj ob unfused haploid nuclei. Secondary mycelium sawv cev rau theem tseem ceeb ntawm lub neej voj voog, tsis zoo li thawj mycelium. Ntxiv mus, theem nrab mycelium muaj lub neej ntev piv rau thawj mycelium. Yog li, qhov no qhia txog qhov sib txawv ntawm thawj thiab theem nrab mycelium.
