Mukusvetukira kwakakosha kumberi kwezvekurima biotechnology, vaongorori kubva kuSweden University of Agricultural Sayenzi vakashandisa CRISPR/Cas9 tekinoroji kugadzira chizvarwa chitsva chembatatisi nekuwedzera kusimba kune ese biotic uye abiotic matambudziko. Kufambira mberi uku kunogona kushandura kurima mbatatisi uye kugadzirisa nyaya dzakakomba dzine chekuita nekushanduka kwemamiriro ekunze uye kuchengetedzwa kwechikafu.
Kubudirira muGenetic Kugadziriswa
Chidzidzo, chakabudiswa mukati Horticulture Research, inotarisa pakugadzirisa genome yembatatisi nekutarisa iyo StDMR6-1 gene. Kusandurwa kwemajini uku kwakonzera mbatatisi dzinoratidza kushingirira kuzvirwere zvakaita sekunonoka blight - kutyisidzira kukuru zvirimwa zvembatatisi pasi rose - pamwe nekushushikana kwezvakatipoteredza semunyu nekusanaya kwemvura. Tekinoroji yeCRISPR/Cas9, inozivikanwa nehunyanzvi hwekugadziridza mageneti, yakabvumira vesainzi kuti vagadzirise kusimba kwechirimwa vasingakanganise goho kana kuti tuber quality.
Kugadzirisa Kuchinja Kwemamiriro ekunze uye Kusagadzikana Kwezvirimwa
Mbatatisi, chirimwa chechitatu chekudya zvakakosha pasi rose, inonyanya kukanganiswa nekushanduka kwemamiriro ekunze, izvo zvinowedzera kuwanda kwezvipembenene nezvirwere. Iyo nzira itsva yekushandura iyo StDMR6-1 gene inopa yakasimba nzira yekudzivirira kurwisa matambudziko aya. Nekuwedzera kudzivirira kwechirwere uye kushivirira kushushikana, idzi mbatatisi dzakagadziridzwa genetics dzinogona kumira zvirinani nemamiriro ezvinhu akaomarara anounzwa nekushanduka kwemamiriro ekunze.
Zvinoreva Sustainable Agriculture
Budiriro iyi ine chekuita nekurima kwakasimba. Kugona kugadzira mbatatisi iyo isinganyanyi kuvimba nemishonga yemakemikari - senge fungicides - inogona kuderedza zvakanyanya kukanganisa kwezvakatipoteredza uye kusimudzira maitiro ekurima. Pamusoro pezvo, zvakawanikwa kubva kutsvagurudzo iyi zvinodarika mbatatisi. Nzira uye ruzivo rwakawanikwa runogona kuzivisa kuvandudzwa kwemajini mune zvimwe zvirimwa, zvichibatsira mukusimba kwekurima kwese.
Zvichaitika mune ramangwana
Basa raErik Andreasson nechikwata chake rinoratidza danho rinovimbisa rekuchengetedza chikafu chedu takatarisana nematambudziko epasi rose. Sezvo kushanduka kwemamiriro ekunze kuri kuramba kuchisimbisa masisitimu ekurima pasi rese, hunyanzvi hwakadai hwakakosha kuti tive nechokwadi chekuti tinokwanisa kuchengetedza huwandu hwekugadzira chikafu. Iko kugona kudzikisa kutsamira pane zvekushandisa zvemakemikari uku uchivandudza kusimba kwechirimwa kunosimbisa kukosha kwekuenderera mberi nekutsvaga nekushandiswa kwemajini tekinoroji.
Kushandiswa kweCRISPR/Cas9 kusimudzira kusimba kwembatatisi kunomiririra kufambira mberi kukuru mune zvekurima biotechnology. Nekugadzirisa zvese zviri zviviri kubatwa nechirwere uye kunetsa kwezvakatipoteredza, tsvakiridzo iyi haingovimbisi chete kushandura kurima mbatatisi asiwo kunovhura nzira yezvekurima kwakasimba. Sezvo isu takatarisana nematambudziko ari kuwedzera kubva mukushanduka kwemamiriro ekunze, hunyanzvi hwakadaro huchave hwakakosha mukuchengetedza chikafu chakatsiga uye chakagadzikana chenguva yemberi.
