Iyo tekinoroji yekuvimbisa kuramba kwezvakanyanya kukosha zvirimwa zvekurima kuperevedza kwemvura iri kugadzirwa pamwe chete nemasayendisiti kubva kuRussia neBelarus, iyo press service yeTomsk State University (TSU) inoshuma munaNovember 17.
Kuwedzera kwehuwandu hwevanhu munyika uye kushanduka kwemamiriro ekunze munyika kunosimudza zvakanyanya nyaya yekuwanikwa kwechikafu kwevanhu. Mashoko kubva kuIntergovernmental Panel on Climate Change (IPCC) anoratidza maitiro ekushanduka kwegwenga nekusanaya kwemvura munzvimbo zhinji dzepasi.
Mubatanidzwa Purofesa weDhipatimendi rePlant Physiology, Biotechnology uye Bioinformatics yeBiological Institute yeTSU Marina Efimova akati:
"Dambudziko ratiri kugadzirisa nevatinoshanda navo kubva kuInstitute of Bioorganic Chemistry yeNational Academy of Sciences yeBelarus uye Institute of Plant Physiology yakatumidzwa zita iri. KA Timiryazev RAS, yakakosha uye inoshandiswa panguva imwe chete.
Masayendisiti anotarisira kushandisa masikirwo emasikirwo - steroid phytohormones uye zvinobva kwavari - sezvishandiso zvekuwedzera kusanaya kwechirimwa kusanaya kwemvura uye ivhu salinity kuramba.
"Asi kuti ushandise chishandiso ichi zvine chinangwa, zvinodikanwa kutsanangura maitiro ekushanda akaiswa nemasikirwo, uye wozoakopa nenzira yenanobiotechnology," Marina Efimova akatsanangura.
Masayendisiti aifarira brassinosteroids - phytohormones inokonzera kushanda kwemaitiro ekudzivirira kwezvirimwa, kunyanya pasi pemamiriro ezvinhu akaipa, akadai sekutonhora kwemamiriro okunze, kuwandisa uye kushaya unyoro, zvirwere, kutarisana nemishonga yezvipembenene nezvimwe zvinonetsa.
Panguva imwecheteyo, kuti uwedzere kubereka uye kushorwa kwezvirimwa, zvinodikanwa kushandisa micro- uye nanomolar concentrations yebrassinosteroids.
"Zviri mukati mebrassinosteroids mumiti zvakaderera zvakanyanya, izvo zvinoita kuti zvive zvisingabviri kuzviparadzanisa, saka zvinhu izvi zvinofanira kuwanikwa nekemikari kubva kune zvigadzirwa zvemiti zviripo," akadaro Marina Efimova.
Masayendisiti kubva kuInstitute of Bioorganic Chemistry yeNational Academy of Sciences yeBelarus vatungamiri venyika mumunda we brassinosteroid synthesis. Naizvozvo, muchirongwa chakabatana, ivo vanozogadzira zvigadzirwa zvemhando iyi ye phytohormones ine rimwe boka rinoshanda rinopa mapuroteni anosunga.
Kumapoka akadaro, vaongorori vanozowedzera mamorekuru anodiwa ayo anozopa zvirimwa zvimiro zvitsva. Mhedzisiro yeakadaro phytohormones pabhari, rapeseed, mbatatisi, Arabidopsis, iyo isingakwanise kurwisa kusanaya kwemvura uye munyu, ichadzidzwa neTSU biologists.
Basa rakabatana revasayendisiti rinozopedzisira ratungamira mukusikwa kwenzira dzekugadzirisa kugona uye kubereka kwezvirimwa vachishandisa bioregulators. Brassinosteroids inofanirwa kushandiswa mukudyara mbeu uye kurapwa kwemidzi yezvirimwa.
Parizvino, TSU iri kushanda nesimba kugadzira nzira nyowani dzekudzora zvimiro zvezvirimwa zvakakurumbira vachishandisa tekinoroji yemazuva ano genomic editing.
Tsvagiridzo yakanangana nekukura zvirimwa zvinobereka zvakanyanya uye zvine hushamwari zvakatipoteredza inoitwa mukati mehurongwa hwechirongwa che "Engineering Biology". Mhedzisiro yavo ichaita kuti kuve nechokwadi chekuchengetedza chikafu cheRussia.
