Qhov sib txawv tseem ceeb ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe yog Saccharomyces cerevisiae yog cov poov xab uas tsim tawm los ntawm budding thaum Schizosaccharomyces pombe yog fission poov xab uas reproducesfission.
Saccharomyces cerevisiae thiab Schizosaccharomyces pombe yog ob hom poov xab uas siv rau kev ua noj thiab ci. Ntxiv mus, ob qho tib si muaj txiaj ntsig zoo li eukaryotic qauv kab mob hauv molecular thiab cell biology. Lawv yog unicellular fungi. Txawm li cas los xij, lawv txoj kev tsim tawm yog txawv. Saccharomyces cerevisiae reproduces ntawm budding thaum Schizosaccharomyces pombe reproduces ntawm fission. Saccharomyces cerevisiae yog puag ncig rau ovoid nyob rau hauv cov duab thaum Schizosaccharomyces pombe yog qws-puab. Lawv muaj cov noob lej zoo sib xws thiab faib cov noob nrog cov eukaryotes siab dua.
Saccharomyces cerevisiae yog dab tsi?
Saccharomyces cerevisiae yog cov poov xab. Nws yog feem ntau hu ua qab zib fungus lossis brewer's poov xab. Nws yog ib qho zoo tshaj plaws-kawm eukaryotic qauv kab mob hauv molecular thiab cell biology. S. cerevisiae kuj tseem tuaj yeem hloov kho caj ces yooj yim. Yog li ntawd, nws yog ib qho tseem ceeb nyob rau hauv ntau yam kev siv biotechnological thiab. Ntxiv mus, cov kab mob no yog siv nyob rau hauv ci, winemaking thiab brewing txij thaum ancient sij hawm. Nws kuj yog siv rau kev lag luam ntawm qee cov tshuaj biopharmaceuticals. S. cerevisiae muaj qee qhov cuam tshuam tsis zoo thiab. Nws muaj feem xyuam rau ntau yam kab mob, suav nrog vaginitis hauv cov neeg mob noj qab haus huv, kab mob ntawm daim tawv nqaij, kab mob hauv cov hlab ntsha thiab cov kab mob ntawm cov kab mob tseem ceeb hauv cov neeg mob tiv thaiv kab mob thiab mob hnyav.
Daim duab 01: Lub paj ntawm Saccharomyces cerevisiae
Structurally, S. cerevisiae yog puag ncig lossis ovoid hauv cov duab. Tsis tas li ntawd, nws yog 5-10 μm hauv txoj kab uas hla. Qhov tseem ceeb tshaj plaws, S cerevisiae reproduces los ntawm budding. Cytokinesis ua rau cov poov xab budding los tsim ob tug ntxhais hlwb. Los ntawm niam cell, budding poov tsim ib bud, thiab ces nws loj hlob thiab detaches ntawm niam poov. Hom no tsis yog huab cua. Nws yog feem ntau pom ntawm cov txiv hmab txiv ntoo siav. S. cerevisiae yog thawj genome uas tau ua tiav tag nrho. Lub genome muaj 16 chromosomes thiab muaj txog 6000 genes.
Schizosaccharomyces pombe yog dab tsi?
Schizosaccharomyces pombe, tseem hu ua fission poov xab, yog ib hom poov xab uas siv hauv brewing thiab ci. Zoo ib yam li S. cerevisiae, S. pombe yog ib qho ntawm cov kab mob uas tau kawm zoo tshaj plaws uas siv los ua cov kab mob eukaryotic hauv molecular thiab cell biology.
Daim duab 02: Fission of Schizosaccharomyces pombe
Structurally, S. pombe yog pas nrig thiab 3 mus rau 4 micrometers inch thiab 7 mus rau 14 micrometers nyob rau hauv ntev. Lub genome yog tus yam ntxwv tag nrho thiab muaj 3 chromosomes, suav nrog kwv yees li 5000 cov noob. S. pombe reproduces ntawm fission. Nws ntiav medial fission thiab tsim ob lub cev sib npaug ntawm tus ntxhais. Thaum lub sij hawm fission, nws tsim ib lub septum los yog cell phaj uas cleaves lub cell ntawm nws midpoint.
Dab tsi yog qhov Zoo sib xws ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe?
- Saccharomyces cerevisiae thiab Schizosaccharomyces pombe yog ob hom poov xab nrog tib lub hlwb.
- Lawv yog ascomycetes fungi.
- Lawv yog cov hlwb dawb.
- Ob leeg yog siv los ua cov qauv eukaryotic hauv molecular thiab cell biology.
- Lawv tau siv dav hauv brewing thiab ci.
- Lawv muaj qee tus lej zoo sib xws.
- Ntxiv mus, t lawv faib cov noob nrog ntau dua eukaryotes.
- Lub 2001 Nobel nqi zog hauv tshuaj tau muab tsub rau Lee Hartwell thiab Paul Nurse rau lawv cov kev tshawb fawb ntawm noob caj noob ces thiab molecular biology ntawm cerevisiae thiab Schiz. pombe, feem.
Qhov txawv ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe yog dab tsi?
Qhov sib txawv tseem ceeb ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe nyob ntawm kev tsim tawm. Saccharomyces cerevisiae yog hu ua budding poov xab txij li thaum nws rov tsim dua los ntawm budding. Nyob rau hauv sib piv, Schizosaccharomyces pombe yog hu ua fission poov xab vim nws reproduces los ntawm fission.
Cov ntawv qhia hauv qab no qhia ntau qhov sib txawv ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe rau ib sab ntawm kev sib piv.
Summary – Saccharomyces cerevisiae vs Schizosaccharomyces pombe
Saccharomyces cerevisiae thiab Schizosacchromyces pombe yog ob hom poov xab kawm dav, uas yog ascomycetes. Lawv yog ib leeg-celled dawb-nyob fungi. Qhov sib txawv tseem ceeb ntawm Saccharomyces cerevisiae thiab Schizosaccharomyces pombe yog tias S. cerevisiae reproduces los ntawm budding thaum S. pombe reproduces los ntawm fission. Ntxiv mus, S. cerevisiae yog puag ncig los yog ovoid nyob rau hauv cov duab thaum S. pombe yog pas nrig-puab. Ob qho tib si feem ntau siv los ua eukaryotic qauv kab mob. Cov hom no qhia cov noob homologous rau tib neeg cov noob.
