Qhov sib txawv tseem ceeb ntawm appressorium thiab haustorium yog tias appressorium tsim cov qauv zoo li lub teeb thaum muaj kab mob, thaum haustorium tsim cov hauv paus zoo li cov kab mob.

Cov kab mob fungal yog heev muaj nyob rau hauv av fungi. Cov fungi no tsim cov qauv tshwj xeeb uas muaj peev xwm tawm ntawm kev nkag mus rau cov nroj tsuag, yog li ua rau muaj kev kis kab mob. Ntxiv mus, cov no yog cov kab mob sib kis uas tus tswv tsev tsis tau txais txiaj ntsig. Appressorium thiab haustorium yog ob qho kev tsim ntawm fungi thaum lub sij hawm cuam tshuam ntawm cov nroj tsuag.

Appressorium yog dab tsi?

Appressorium yog hom cell tshwj xeeb uas muaj nyob hauv cov kab mob. Lawv feem ntau muaj nyob rau hauv cov kab mob fungal uas ua rau cov nroj tsuag kab mob. Appressorium yog ib tug flattened hyphae qauv. Tsis tas li ntawd, cov qauv no muaj peev xwm nkag mus rau tus tswv tsev thiab loj hlob hauv tus tswv tsev. Cov kab mob tsim muaj nyob rau hauv tus tswv tsev hauv kev teb rau cov tshuaj lom neeg thiab lub cev stimulations.

Lub appressorium tsim pib ntawm qhov kawg ntawm cov kab mob fungal. Tsis tas li ntawd, kev nthuav tawm ntawm cov ntsiab lus ntawm cov spores mus rau lub appressorium tshwm sim tom ntej, ua rau tsim cov septum ntawm lub caj dab ntawm appressorium. Yog li ntawd, appressorium cov ntaub ntawv zoo li lub teeb ntawm cov nroj tsuag thaum kis kab mob.

Daim duab 01: Appressorium

Ntxiv mus, thaum lub sij hawm maturation ntawm lub appressorium, nws ruaj khov nws tus kheej rau cov nroj tsuag nto. Cov laus appressorium ces secretes ib txheej tuab ntawm melanin. Nrog rau kev tso tawm ntawm melanin, turgor siab hauv appressorium nce thiab qhov no ua rau kev nkag mus ntawm hyphae mus rau hauv cov nroj tsuag cuticle, ua rau tus kab mob. Tsis tas li ntawd, appressorium yog lub luag haujlwm rau fungal xeb hauv cov nroj tsuag.

Haustorium yog dab tsi?

Haustorium yog lub hauv paus zoo li cov qauv tsim los ntawm cov kab mob. Lawv loj hlob mus rau hauv av. Tsis tas li ntawd, lub luag haujlwm tseem ceeb ntawm haustorium yog nqus cov as-ham thiab dej los ntawm cov av. Haustorium yog ib qho tseem ceeb hauv cov kab mob uas ua rau cov fungi kis tau cov nroj tsuag. Yog li, haustorium tuaj yeem nkag mus rau cov cag ntoo thiab nqus cov nroj tsuag cov as-ham. Nws yog ib tug feature ntawm parasitic fungi.

Daim duab 02: Haustorium

Lub haustorium tuaj yeem nkag mus rau hauv nruab nrab ntawm phab ntsa cell thiab plasma membrane ntawm cov nroj tsuag. Ntxiv mus, lawv muaj cov siphon zoo li kev ua haujlwm uas pab txhawb kev nqus ntawm cov as-ham los ntawm cov nroj tsuag.

Dab tsi yog qhov zoo sib xws ntawm Appressorium thiab Haustorium?

  • Ob leeg yog cov qauv muaj nyob hauv cov kab mob
  • Lawv muaj peev xwm nkag mus rau hauv cov chaw cog qoob loo.
  • Ob leeg nqus cov as-ham thiab dej.
  • Ntxiv mus, cov qauv no tseem ceeb hauv kev txhim kho cov kab mob fungal.

Qhov txawv ntawm Appressorium thiab Haustorium yog dab tsi?

Appressorium thiab haustorium yog cov qauv zoo sib xws ntawm cov kab mob fungi uas koom nrog ua rau cov kab mob nroj tsuag. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm appressorium thiab haustorium yog cov qauv uas lawv tsim thaum muaj kab mob; appressorium tsim cov qauv bulbous thaum haustorium tsim cov qauv hauv paus zoo li tus kab mob.

Summary – Appressorium vs Haustorium

Yeej, appressorium thiab haustorium yog ob lub qauv muaj nyob rau hauv feem ntau cov kab mob fungi. Tsis tas li ntawd, lawv nkag mus rau cov nroj tsuag hosts thiab ua rau muaj kab mob hauv cov nroj tsuag. Thaum nkag mus, lawv nqus cov as-ham uas ua rau muaj kev phom sij rau cov nroj tsuag. Qhov sib txawv tseem ceeb ntawm appressorium thiab haustorium yog tias yav dhau los ua cov qauv bulbous thaum cov tom qab tsim cov hauv paus zoo li cov qauv.
