I-China yenza impumelelo ekuthinteleni isifo sentsholongwane ye-Solanaceae

I-China yenze impumelelo ekuthinteleni isifo se-virus ye-Solanaceae emva kokusebenzisa ichiza le-dsRNA nano nucleic acid, ngokwe-academy yaseTshayina yesayensi yezolimo.

Iqela leengcali lisebenzise ngendlela entsha i-nanomaterials ukuthwala i-nucleic acids ngokusebenzisa umqobo we-pollen, ukuhambisa i-dsRNA ngaphandle koncedo lwangaphandle lomzimba, kunye nokuvula i-RNAi emva kokunikezelwa kwiincinci ze-pollen ukunciphisa ukuthuthwa kwentsholongwane kwimbewu.

Ukusetyenziswa kwe-dsRNA nanoparticles yokulawula izinambuzane kuthathwa njengobuchwephesha benguqu kwintsimi yokukhusela izityalo kwixesha elizayo.

Kwiminyaka yakutshanje, iqela lizibophelele ekuphuhliseni iindlela zokukhusela eziluhlaza kunye nokulawula izinambuzane kunye nezifo, kwaye lenze uphando olucwangcisiweyo malunga nokujoliswe kuyo ngokuchanekileyo kunye nokusingqongileyo.

Uphononongo luqhathanise iziphumo ze-antiviral zeendlela ezine zokuhambisa i-dsRNA kwizityalo, ukungena, ukutshiza, ukucwiliswa kweengcambu, kunye ne-pollen internalization.

Kwaye iziphumo zibonisa ukuba i-HACC-dsRNA NPs ye-biocompatible inokusetyenziswa njenge-biomolecular transport vector, kunye nokuba yinto enokuthwala i-non-transgenic trait manipulation yezityalo. Ukuhanjiswa okuthe nkqo kwezifo zentsholongwane yezityalo kunokuncitshiswa, ngaloo ndlela kuncitshiswe izinga lokuthwala intsholongwane lembewu yenzala ngokufakwa ngaphakathi kwepollen ngeNPs.

Ezi ziphumo zibonisa iingenelo zeteknoloji ye-NPs-based RNAi ekuzaleni ukuxhathisa izifo kunye nokuphuhlisa izicwangciso ezintsha zokuzala izifo zezityalo.

Ingxelo yasekwa kwi-ACS Applied Materials & Interfaces, enye yeejenali enegunya eChina.

Nazi ezinye izitshabalalisi zokuthintela izinambuzane kwimifuno.
