Isithombe: Isithombe Esiphambene Nesigaba Sebhayoloji Yemvubelo Enkulu

Umfanekiso wesayensi onesinqumo esiphezulu obonisa isakhiwo esiyinkimbinkimbi samaseli semvubelo ye-Saccharomyces cerevisiae lager, ogqamisa ama-nuclei, amahlumela, kanye nezindonga zamaseli ezikhanyayo.
Cross-Sectional Portrait of Lager Yeast Biology
Lesi sithombe sibonisa umfanekiso wesayensi osezingeni eliphezulu, ogxile endaweni ethile we-Saccharomyces cerevisiae, uhlobo lwemvubelo olusetshenziswa ekuvuthweni kwe-lager yesitayela saseDenmark. Ukwakheka kugxila kumaseli emvubelo amaningana akhanyayo, amade akhiwe ngamathoni athambile, athambile e-beige avusa kokubili ukunemba kwelabhorethri kanye nobuhlakani bezinto eziphilayo. Enkabeni, amaseli amabili amakhulu abusa uhlaka, ahlanganiswe nesakhiwo esiqhakazayo esiveza ngokubonakalayo inqubo yokuzala yemvubelo. Izindonga zamaseli awo zibonakala zingqimba futhi zigobile kancane, zinikeza umuzwa wokuthinta wobukhulu nokuqina. Ngaphakathi kweseli ngalinye, inhlangano yangaphakathi iboniswa ngokucophelela: i-nucleus evelele enezinhlayiya ezixubile ezifana ne-chromatin ihlezi phakathi, izungezwe indawo ye-cytoplasmic ethambile. Ama-vacuole athambile, ama-membrane folds, kanye nezakhiwo ezifana ne-vesicle zibonakala kancane, zinegalelo embonweni wobunzima obukhulu be-microscopic.
Ukukhanya kuthambile futhi kuyasabalala, kukhanyisa kancane kuwo wonke amaseli ngenkathi kugcizelela ubukhulu obuthathu be-membrane kanye nezingxenye zangaphakathi. Lokhu kukhanya okucashile kudala umuzwa wokujula nokuzola, okuvumela imininingwane yesayensi ukuthi ihambisane nobuhle obucishe bube bobuciko. Ingemuva lifiphele ngamabomu, ngamaseli emvubelo akude, angagxilile abonakala njengezithombe ezithambile. Lokhu kujula kwensimu okukhethiwe kudonsela ukunaka eqenjini eliyinhloko lamaseli futhi kuqinise umbono ofana ne-microscope, njengokungathi umbukeli ubekwe ngqo endaweni eqondile yesistimu yokuthwebula izithombe ephezulu.
Ubuhle obubonakalayo bulinganisa ukunemba kobuchwepheshe ngethoni ekhangayo, okwenza umfanekiso ufanelekele izimo zemfundo, ucwaningo, noma imboni yokwenza ubhiya. Ukunaka ukwakheka kwamaseli—izindawo ezihlumayo, ama-nuclei, ukuthungwa kwe-cytoplasmic, kanye nama-membrane anezingqimba eziningi—kuthatha izisekelo eziyisisekelo zezinto eziphilayo ngenkathi kusaveza imvubelo njengohlelo lokuphila oluhlelekile kahle. Iphalethi elithulile, umugqa omuhle, kanye nezithunzi ezihlelwe kahle kunikela emqondweni wokucwengwa kwezinto eziphilayo, kugqamisa ukusebenza kwangaphakathi okubalulekile okuqhuba ukuvutshelwa kwe-lager futhi kulolonge ukunambitheka, iphunga, kanye nobuntu bobhiya besitayela saseDenmark. Lokhu kumelwa okuningiliziwe kusebenza njengereferensi yesayensi kanye nokuhlola okuhehayo okubonakalayo kwezwe elincane kakhulu lebhayoloji yemvubelo ye-lager.
