Nguva pfupi yadarika, Soil Pest Control Innovation Team yeInstitute of Plant Protection, Chinese Academy of Agricultural Sciences, yakaburitswa pamhepo mupepanhau rine mukurumbira pasi rose rinonzi “Journal of Hazardous Materials” rakanzi “Transcriptome inoburitsa huturu hwehupfu hwedimethyl disulfide nekubata uye kufutisa paMeloidogyne. incognita kuburikidza necalcium channel -mediated oxidative phosphorylation" bepa rekutsvagisa. Iri bepa rinoongorora biochemical uye molecular maitiro emusiyano mubiological chiitiko chevhu fumigant dimethyl disulfide.(DMDS)kurwisa mudzi-knot nematodes pasi pemaitiro maviri akasiyana ekuita: kubata kuuraya uye kupfuta, uye inopa ruzivo rwesainzi uye nemashandisirwo ekushandiswa kweiyo nyowani fumigant DMDS mazano matsva.
Kudzivirirwa nekudzora zvirwere zvemidzi-knot nematode muvhu idambudziko repasi rose, uye mishonga yemakemikari yakaita basa rakanaka mukudzivirira nekudzora zvirwere zvegoho nematode. Mishonga yevhu inoshandiswa zvakanyanya kudzora zvipembenene zvevhu nekuda kwekugadzikana kwadzo uye kushandiswa kwakanaka. DMDS rudzi rutsva rweivhu rinopfungaira, rinochengetedza zvakatipoteredza uye rine tarisiro yakakura yekushandisa. Sezvo paine mutsauko munzira mabatirwo efumigants uye echinyakare vanobata vamiririri vanoita pane zvakanangwa zvipenyu, chidzidzo ichi chakaongorora mhedzisiro yeDMDS panematodes kubva pamaonero maviri ekuuraya nekuputira, zvichitora mutsauko muhuturu hweDMDS kune nematodes. entry point. Mechanism.
Chidzidzo ichi chakaratidza zvizere kuti mumiririri anopinda muchinhu chinotarirwa midzi-knot nematode nenzira dzakasiyana pasi pemaitiro maviri ekuita: fumigation uye kuuraya kubata, kukuvadza chimiro chezvikamu zvakasiyana zvenematode, kukanganisa nzira dze calcium ion muzvimiro zvakasiyana, uye zvinokanganisa. zvakasiyana-siyana zve oxidative phosphorylation mukufema. . Mune iyo nzira yekuuraya yekubata, DMDS inopinda yakananga mumuviri wenematode kuburikidza nemadziro emuviri, inoparadza madziro emuviri uye tsandanyama physiological chimiro chenematode, inoshanda sechinhu chisina kubatana, inokanganisa ATP synthase, uye inomutsa kufema kwenematode. Munzira yefumigation, DMDS inopinda mumuviri wenematode kuburikidza neolfactory perception-oxygen exchange process, uye pakupedzisira inobata pamhepo yekufema erekitironi yekutakura cheni yakaoma IV kana yakaoma I, ichipfuura nekukuvadza kweoxidative, zvichikonzera kufa kwenematode. Chidzidzo ichi chinobatsira kutungamira mashandisirwo ezvinonhuhwira zvakachengeteka, zvesainzi uye nemazvo, uye zvakare inopfumisa dzidziso yemafumigant maitiro ekuita.
The Institute of Plant Protection yeChinese Academy of Agricultural Sciences ndiyo yakapedza bepa. Wang Qing, mudzidzi akapedza kudzidza, ndiye munyori wekutanga webepa, uye mubatsiri muongorori Yan Dongdong ndiye munyori anowirirana. Mutsvakurudzi Cao Aocheng, mutsvakurudzi Wang Qiuxia nevamwe vakapa mazano pamusoro pebasa rekutsvakurudza. Iri basa rekutsvagisa rakatsigirwa neNational Natural Science Foundation yekuChina uye National Key Research and Development Program.
