Tsis ntev los no, Kev Tshawb Fawb tau luam tawm tsab xov xwm tshuaj xyuas uas cov kws tshawb fawb tau tshawb pom tias cov proteins hauv ferns tuaj yeem siv los tawm tsam cov kab tsuag qoob loo thiab xav tias yuav dhau los ua ib tiam tshiab ntawm cov tshuaj tua kab zoo heev.
Cov fern proteins no tau ua pov thawj zoo hauv kev sim tshuaj tiv thaiv kab tsuag uas tau tsim kev tiv thaiv rau cov protein Bt uas twb muaj lawm. Qhov kev tshawb pom tau suav tias yog qhov kev tawg loj vim tias nws tau tsim cov ferns ua qhov chaw ntawm cov molecules tshiab.
Kab lus no feem ntau piav qhia txog cov ntsiab lus hauv qab no:
Kev tshawb nrhiav thiab kev siv ntawm fern proteins:Cov protein tshwj xeeb no tau tshawb pom los ntawm cov kws tshawb fawb hauv ferns tau pom tias muaj txiaj ntsig zoo inhibitory cuam tshuam rau cov kab tsuag qoob loo hauv kev sim kuaj. Qhov no qhia tau hais tias ferns tuaj yeem muaj kev cuam tshuam loj rau kev ua liaj ua teb kev tswj kab tsuag raws li qhov chaw ntawm bioactive molecules tshiab.
Muaj peev xwm tiv thaiv kab tsuag:Cov fern proteins no muaj txiaj ntsig zoo tiv thaiv kab tsuag uas tau tsim kev tiv thaiv rau cov protein Bt uas twb muaj lawm, ib qho tshuaj biopesticide feem ntau siv. Cov cuab yeej no ua rau fern proteins yog ib tus neeg sib tw muaj zog los daws qhov teeb meem ntawm kev tiv thaiv kab tsuag.
Genetic engineering applications:Cov kab lus hais tias ntxiv cov noob rau cov fern proteins rau cov qoob loo xws li pob kws thiab taum pauv tuaj yeem tiv thaiv cov qoob loo zoo los ntawm Bt protein-resistant pests. Qhov no qhia tau hais tias nws muaj peev xwm siv tau cov proteins no los ntawm kev tsim cov noob caj noob ces.
Kev cia siab rau kev nyab xeeb thiab kev ua tau zoo: Cov kws tshawb fawb vam tias cov tshuaj tua kab tshiab no yuav yog "tsuas yog" tshuaj tua kab. Qhov no txhais tau hais tias lawv zoo ib yam li Bt cov proteins kom muaj kev nyab xeeb thiab siv tau zoo, tab sis sib txawv txaus los tua kab uas tau tsim los tiv thaiv Bt.
Lub ntsiab lus xaus ntawm txoj kev tshawb no yog kev tshawb pom ntawm tsev neeg tshiab ntawm cov tshuaj tua kab mob los ntawm ferns. Cov proteins no, tshwj xeeb tshaj yog txawv los ntawm genus Pteris (Pterodes) nrog rau ob qho kev txiav txim ntawm ferns (Spermaceae thiab Pteridophyllales), tau pom tias muaj txiaj ntsig zoo tiv thaiv cov kab tsuag tseem ceeb lepidopteran ntawm pob kws thiab taum. Cov noob taum hloov cov pob kws thiab taum pauv cov nroj tsuag uas tsim cov proteins no tiv taus kab ntau dua li cov nroj tsuag tswj. Qhov tseem ceeb, txawm hais tias cov proteins no yog cov hauv paus chiv keeb, lawv cov qauv zoo ib yam li peb lub npe Cry protein ntawm Bacillus pasteuriensis (Bt). Tab sis tsuas muaj ob ntawm peb tus yam ntxwv tseem ceeb thiab tsis muaj C-terminal domain uas feem ntau tsim nyog rau lawv txoj haujlwm. Ob lub fern proteins nyob rau hauv txoj kev tshawb no muaj txiaj ntsig zoo tiv thaiv kab mob khaub thuas kab mob uas tiv taus Bt peb-domain Cry protein Cry1Fa lossis Cry2A.127. Yog li ntawd, qhov no sawv cev rau tsev neeg tshiab ntawm cov kab mob tua kab mob nrog lub peev xwm los ua ib qho cuab yeej rau kev tswj kab tsuag yav tom ntej.
