Qhov sib txawv tseem ceeb ntawm cov poov xab thiab fission poov xab yog cov poov xab yog Saccharomyces cerevisiae uas tsim ib lub paj los ntawm niam lub cell thaum lub sij hawm yug me nyuam thaum fission poov xab yog Schizosaccharomyces pombe uas faib los ntawm medial fission.
Budding poov xab Saccharomyces cerevisiae thiab fission poov xab Schizosaccharomyces pombe yog ob yam kab mob zoo heev hauv cov kev tshawb fawb yooj yim. Ob leeg yog unicellular ascomycete fungi uas tsim asci. Lawv muaj cov yam ntxwv zoo genomes. Cov poov xab rov tsim dua ntawm budding thaum fission poov xab reproduces ntawm fission. Ntxiv mus, budding poov pib cytokinesis ntawm G1 theem thaum fission poov xab pib cytokinesis ntawm G2 theem.
Npau suav teb yog dab tsi?
Budding poov xab los yog Saccharomyces cerevisiae yog hom poov xab uas rov tsim dua los ntawm budding. Nws tsim ib lub pob me me los ntawm niam cell. Tom qab ntawd lub paj loj hlob thiab ua tiav qhov kev faib. Thaum matured, tus ntxhais cell detaches los ntawm niam cell thiab nyob raws li ib tug neeg ywj siab poov xab cell. Lub cytokinesis ntawm budding poov pib ntawm G1 theem. Nws kuj xaiv nws lub dav hlau faib thaum pib ntawm lub voj voog ntawm tes. Ntxiv mus, budding poov xab ntseeg tau tias muaj feem ntau yog diploid, tsis zoo li fission poov xab. Budding poov muaj ib puag ncig.
Daim duab 01: Kab Npauj Npaim
Nyob rau hauv cov poov xab, microtubules yog dispensable rau cell polarization. Budding poov tsis txhob siv cov chaw faib yav dhau los rau kev tsim ntawm tus ntxhais bud vim nws ua rau cell tuag. Yog li ntawd, nws xaiv qhov chaw tshiab rau kev loj hlob.
Fission Poov yog dab tsi?
Fission poov xab Schizosaccharomyces pombe yog ib hom poov xab uas rov tsim dua los ntawm fission. Thaum lub sij hawm faib, fission poov xab tsim ib lub septum los yog cell phaj nyob rau hauv nruab nrab ntawm lub cell thiab faib nws mus rau hauv ob lub vaj huam sib luag tus ntxhais. Zoo ib yam li budding poov xab, fission poov xab kuj yog ib tug nrov qauv eukaryote. Nws ruaj khov li haploid.
Daim duab 02: Fission Poov
Cov hlwb ntawm fission poov xab yog pas nrig. Hauv fission poov xab, microtubules ua lub luag haujlwm tseem ceeb hauv kev kos cov cell ncej rau kev loj hlob los ntawm kev tso cov cim cim tseg. Tsis zoo li budding poov xab, fission poov xab siv qhov chaw faib yav dhau los ua qhov chaw loj hlob tshiab.
Dab tsi yog qhov zoo sib xws ntawm Budding Poov thiab Fission Poov?
- Budding poov thiab fission poov xab yog ob hom poov xab raws li kev loj hlob.
- Lawv yog unicellular dawb-nyob fungi belongs rau Ascomycota.
- Ob hom siv lub nplhaib ua haujlwm raws li actomyosin los ua kev faib cell.
- Cov lipids loj hauv ob hom poov xab yog glycerophospholipids, sphingolipids, thiab sterols.
- Ob lub budding poov xab thiab fission poov xab muab ib qho yooj yim-rau-manipulate genetic system rau kev kawm lub cell cycles.
Dab tsi yog qhov txawv ntawm Budding Poov thiab Fission Poov?
Qhov sib txawv tseem ceeb ntawm budding poov xab thiab fission poov xab yog tias budding yog ib txoj kev luam tawm ntawm budding poov xab, thaum fission yog txoj kev luam tawm ntawm fission poov xab. Budding poov siv lub sij hawm ncua ntawm lub sij hawm nyob rau hauv G1 theem thaum fission poov xab siv lub sij hawm ncua ntawm lub sij hawm nyob rau hauv G2 theem. Ntxiv mus, budding poov xab yog ib tug spherical unicellular eukaryote thaum fission poov xab yog ib tug pas nrig-shaped unicellular eukaryote.
Cov hauv qab no infographic tabulates ib sab ntawm qhov sib txawv ntawm budding poov xab thiab fission poov xab.
Summary – Budding Poov vs Fission Poov
Ob lub budding poov xab thiab fission poov xab muaj cov genomes kawm tau zoo, thiab lawv muab yooj yim-rau manipulate genetic systems rau kawm lub cell cycles thiab chromosome dynamics. Nyob rau hauv budding poov xab, me me cell pinch los yog bud tawm ntawm niam cell. Nyob rau hauv fission poov xab, ib tug septum los yog cell phaj yog tsim nyob rau hauv nruab nrab ntawm lub cell thiab faib ua ob tug sib npaug zos tus ntxhais cell. Cov poov xab siv sij hawm ntau dua hauv G1 theem thaum fission poov xab siv sij hawm ntau dua hauv G2 theem. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm budding poov xab thiab fission poov xab.
