Qhov Tseem Ceeb Qhov txawv - Micropropagation vs Somatic Cell Hybridisation
Clonal propagation yog ib qho txheej txheem uas ua rau muaj coob tus genetic zoo tib yam nroj tsuag los ntawm asexual propagation. Micropropagation yog ib hom clonal propagation. Micropropagation tuaj yeem txhais tau tias yog cov txheej txheem uas ua rau muaj ntau cov nroj tsuag progeny los ntawm cov nroj tsuag cog los ntawm cov txheej txheem cog qoob loo niaj hnub. Ntau yam tshiab nrog cov yam ntxwv sib xyaw yog tsim los ntawm hybridization. Kev loj hlob ntawm cov nroj tsuag hybrid los ntawm fusion ntawm ob somatic cell protoplasts ntawm ob hom sib txawv ntawm tib hom lossis ob hom nroj tsuag sib txawv yog hu ua somatic cell hybridization. Kev sib xyaw ntawm ob lub nuclei ua rau muaj heterokaryote nrog kev sib xyaw ntawm cov yam ntxwv ntawm ob hom nroj tsuag. Yog li, cov txheej txheem somatic cell hybridization tso cai rau kev tswj hwm ntawm cellular genomes. Qhov sib txawv tseem ceeb ntawm micropropagation thiab somatic cell hybridization yog tias micropropagation yog cov txheej txheem propagation ntawm cov nroj tsuag thaum somatic cell hybridization yog genome manipulation txheej txheem los ntawm somatic cell protoplast fusion.
YMicropropagation yog dab tsi?
Cov nroj tsuag muaj peev xwm nthuav tawm los ntawm txoj kev sib deev thiab txoj kev sib deev. Noob tiam yog siv nyob rau hauv kev sib deev propagating txheej txheem thaum vegetative qhov chaw yog siv nyob rau hauv lub asexual hom. Asexual propagation muaj ntau yam zoo tshaj li kev sib deev propagation txij li thaum asexual propagation yog muaj peev xwm tsim tau ib tug loj tus naj npawb ntawm genetic zoo tib yam nroj tsuag nyob rau hauv ib lub sij hawm luv luv. Micropropagation yog ib txoj kev ntawm asexual propagation uas yog ua nyob rau hauv vitro tej yam kev mob. Micropropagation yog ib qho txheej txheem ntawm kev cog qoob loo uas siv cov txheej txheem cog qoob loo. Nws yog ib qho kev xyaum ntawm kev tsim cov nroj tsuag loj heev los ntawm cov nroj tsuag uas siv cov txheej txheem cog qoob loo niaj hnub.
Cov txheej txheem micropropagation muaj ob peb kauj ruam raws li hauv qab no.
- Kev xaiv thiab kev loj hlob ntawm cov khoom cog rau peb lub hlis raws li kev tswj hwm
- Kev xaiv ntawm kev cog qoob loo, thiab pib thiab tsim kab lis kev cai hauv qhov nruab nrab tsim nyog
- Multiplication of tua los yog sai embryo tsim los ntawm explants
- Txoj kev tua mus rau nruab nrab kom loj hlob sai rau hauv kev tua
- Tsim cov nroj tsuag hauv av
Daim duab 01: Micropropagation
Micropropagation yog ib txoj kev siv dav rau kev sib faib cov nroj tsuag transgenic. Thaum cov nroj tsuag tsis tsim cov noob los yog tsis teb rau ib txwm vegetative reproduction, micropropagation yog cov txheej txheem siv los tsim clone nroj tsuag.
Somatic Cell Hybridisation yog dab tsi?
Somatic cell hybridization yog ib hom kev hloov kho caj ces hauv cov nroj tsuag. Nws yog cov txheej txheem hybridization uas pab txhawb kev tswj hwm ntawm ob lub genomes los ntawm protoplast fusion. Ob hom nroj tsuag txawv lossis ob hom sib txawv ntawm tib hom yog fused ua ke kom sib xyaw lawv cov yam ntxwv thiab ua kom muaj ntau yam hybrid tshiab. Cov yam ntxwv yog pauv mus rau hybrid los ntawm somatic cell hybridization. Cov txheej txheem no yog thawj zaug los ntawm Carlson hauv Nicotiana glauca.
Somatic cell hybridization txheej txheem yog ua los ntawm cov kauj ruam hauv qab no.
- Kev xaiv ntawm qhov chaw ntawm protoplast
- Kev tsim cov protoplasts los ntawm kev tshem cov phab ntsa ntawm tes ntawm ib lub xovtooj ntawm txhua hom cell
- Kev sib xyaw ntawm ob lub protoplasts thiab ob lub nuclei los ntawm kev siv hluav taws xob los yog tshuaj kho mob
- Induction ntawm cell phab ntsa synthesis hauv somatic cell hybrid (heterokaryote)
- Kev loj hlob ntawm fused hybrid hauv callus kab lis kev cai
- Kev txheeb xyuas thiab cim ntawm cov nroj tsuag somatic hybrid
- Kev loj hlob ntawm cov nroj tsuag tiav hauv av
Daim duab 02: Somatic Cell Hybridization lossis Protoplast Fusion
Tsiaj cov hlwb kuj tuaj yeem sib xyaw ua ke, thiab cov hybrids tuaj yeem tau txais rau ntau lub hom phiaj xws li kawm thiab tswj cov noob qhia thiab kev faib cell, kawm malignant transformations, kawm viral replication, daim ntawv qhia cov noob lossis chromosomes, los tsim cov tshuaj tiv thaiv monoclonal, thiab lwm yam.

Summary – Micropropagation vs Somatic Cell Hybridisation
Micropropagation yog ib qho txheej txheem tseem ceeb rau kev cog qoob loo sai. Nws siv cov txheej txheem kab lis kev cai cog qoob loo los tsim ntau cov noob caj noob ces zoo tib yam. Somatic cell hybridization yog cov txheej txheem hybridization uas tsim cov hybrids tshiab los ntawm kev sib xyaw ntawm ob hom somatic cell protoplasts. Qhov no yog qhov txawv ntawm micropropagation thiab somatic cell hybridization. Somatic cell hybridization yog qhov muaj txiaj ntsig zoo rau kev tsim cov kev sib txawv tshiab lossis cov hybrids intergenic.
