Tsis ntev los no, Pab Pawg Soil Pest Control Innovation ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv, Suav Academy ntawm Kev Tshawb Fawb Txog Kev Ua Liaj Ua Teb, tau luam tawm online hauv phau ntawv xov xwm thoob ntiaj teb "Journal of Hazardous Materials" lub npe "Transcriptome nthuav tawm qhov sib txawv ntawm cov tshuaj lom ntawm dimethyl disulfide los ntawm kev sib cuag thiab fumigation ntawm Meloidogyne. incognita los ntawm calcium channel -mediated oxidative phosphorylation " ntawv tshawb fawb. Daim ntawv no txheeb xyuas cov txheej txheem biochemical thiab molecular ntawm qhov sib txawv hauv kev ua haujlwm lom neeg ntawm cov av fumigant dimethyl disulfide(DMDS)tiv thaiv cov hauv paus-knot nematodes nyob rau hauv ob hom kev sib txawv ntawm kev ua: hu rau tua thiab fumigation, thiab muab cov ntaub ntawv rau kev tshawb fawb thiab siv tau zoo ntawm cov tshiab fumigant DMDS cov tswv yim tshiab.
Kev tiv thaiv thiab tswj cov kab mob hauv paus-knot nematode hauv av yog qhov teeb meem thoob ntiaj teb, thiab cov tshuaj nematicides tau ua lub luag haujlwm zoo hauv kev tiv thaiv thiab tswj cov kab mob qoob loo nematode. Av fumigants tau dav siv los tswj cov kab tsuag hauv av vim lawv cov teebmeem ruaj khov thiab siv tau zoo. DMDS yog hom tshiab ntawm cov av fumigant, uas yog ib puag ncig tus phooj ywg thiab muaj kev thov dav dav. Txij li thaum muaj qee qhov sib txawv ntawm txoj kev fumigants thiab cov tshuaj tiv thaiv ib txwm ua rau cov kab mob hauv lub hom phiaj, qhov kev tshawb fawb no tau tshawb txog cov teebmeem tshwj xeeb ntawm DMDS ntawm nematodes los ntawm ob qhov kev xav ntawm kev sib cuag tua thiab fumigation, noj qhov sib txawv ntawm cov tshuaj lom ntawm DMDS rau nematodes. nkag point. Mechanism.
Txoj kev tshawb no qhia meej tias tus neeg sawv cev nkag mus rau lub hom phiaj kab mob hauv paus-knot nematode los ntawm ntau txoj hauv kev hauv ob hom kev ua: fumigation thiab kev sib cuag tua, ua rau cov qauv ntawm ntau qhov chaw ntawm nematode, cuam tshuam nrog calcium ion channels hauv cov qauv sib txawv, thiab cuam tshuam. sib txawv complexes ntawm oxidative phosphorylation nyob rau hauv ua pa. . Nyob rau hauv kev sib cuag tua hom, DMDS ncaj qha nkag mus rau hauv nematode lub cev los ntawm lub cev phab ntsa, rhuav tshem lub cev phab ntsa thiab cov leeg nqaij physiological qauv ntawm nematode, ua raws li tus neeg sawv cev uncoupling, cuam tshuam nrog ATP synthase, thiab txhawb nqa nematode txoj kev ua pa. Nyob rau hauv txoj kev fumigation, DMDS nkag mus rau hauv lub cev nematode los ntawm olfactory perception-oxygen exchange process, thiab thaum kawg ua rau lub pa electron thauj saw complex IV los yog complex I, superimposing nrog oxidative kev puas tsuaj, ua rau cov nematode tuag. Txoj kev tshawb no pab qhia kev siv cov fumigants muaj kev nyab xeeb dua, kev tshawb fawb thiab ua tau zoo, thiab tseem txhawb txoj kev xav ntawm fumigant action mechanisms.
Lub koom haum ntawm Kev Tiv Thaiv Kev Tiv Thaiv ntawm Suav Academy ntawm Kev Tshawb Fawb Txog Kev Ua Liaj Ua Teb yog lub tsev uas ua tiav daim ntawv. Wang Qing, tus tub kawm tiav, yog thawj tus sau ntawv, thiab tus kws tshawb fawb koom nrog Yan Dongdong yog tus kws sau ntawv. Tus kws tshawb fawb Cao Aocheng, tus kws tshawb fawb Wang Qiuxia thiab lwm tus tau qhia txog kev tshawb fawb ua haujlwm. Txoj haujlwm tshawb fawb no tau txais nyiaj los ntawm National Natural Science Foundation ntawm Tuam Tshoj thiab National Key Research thiab Development Program.
