Muva nje, ithimba lenhlabathi elilawulayo lenhlabathi le-Institute Card of Trap Protection, Chinese Academy of Ezolimo Ezolimo "Ijenali yezinto eziyingozi" I-Incognita ngokusebenzisa i-calcium Channel -mediated oxidative phosphorylation "iphepha lokucwaninga. Leli phepha lihlaziya izindlela ze-biochemical kanye nama-molecular of the umehluko emisebenzini yemvelo yenhlabathi fumigant dimethyl disbeffide(DMDS)Ngokulwa ne-nematode ye-ROOT-Knot ngaphansi kwezindlela ezimbili ezihlukile zesenzo: Ukubulawa kokubulawa kanye nokugcwala, futhi kuhlinzeka ngemininingwane yohlelo lokusebenza olusha lwe-Fumigant DMDS New Imibono emisha.
Ukuvimbela kanye nokulawulwa kwezifo ze-tempatode zezimpande enhlabathini kuyinkinga yomhlaba wonke, futhi amakhemikhali ama-nematicides adlale indima enhle ekuvinjelweni nasekulawuleni kwezifo zezitshalo ze-nematode. Ama-fumigants wenhlabathi asetshenziswa kabanzi ukulawula izinambuzane zenhlabathi ngenxa yemiphumela yazo ezinzile nokusetshenziswa kahle. Ama-DMDs luhlobo olusha lwenhlabathi fumigant, okuyinto enobungane nemvelo futhi enamathemba wohlelo lokusebenza olubanzi. Njengoba kunomehluko othile endleleni ama-fumigants kanye ne-ejenti yokuxhumana yendabuko ethambekweni, lolu cwaningo luhlole imiphumela ethile ye-DMDS kuma-nematode wokubulawa nokuhlaselwa kwama-DMDs kuma-nematode njenge Iphuzu lokungena. Indlela.
Ucwaningo luveze ngokugcwele ukuthi i-ejenti ingena kwithagethi ye-organcy root-knot nematode ngezindlela ezahlukahlukene zokusebenza: Fumigation kanye nokubulawa kweziteshi ze-calcium ion ezinhlakeni ezahlukene, futhi zithinta izakhiwo ezihlukile ze-phosphorylation ye-oxidative ekuphefumuleni. . Kwimodi yokubulala oxhumana naye, ama-DMDs angena ngqo emzimbeni we-nematode ngodonga lomzimba, abhubhise udonga lomzimba kanye nokwakheka komzimba we-nematode, kuphazamisa ukuphefumula kwe-ATP, futhi kuvuse ukuphefumula kwe-ATP. Ngendlela yokuhlanza, ama-DMDS angena emzimbeni we-nematode ngokusebenzisa inqubo yokungena kwe-olfactory-oxygen, futhi ekugcineni asebenza kwi-Electron Transport chain eyinkimbinkimbi ye-IV noma eyinkimbinkimbi, enobunzima bokulimala kwe-nematode. Lolu cwaningo lusiza ukuqondisa ukusetshenziswa kwama-fumigants ngokuphepha, ngokwesayensi nangokuphumelelayo, futhi futhi futhi anothise umbono wezindlela zokwenza okuthile.
Isikhungo sokuvikelwa kwesitshalo se-Chinese Academy of Agricultural Sciences yiyunithi eqeda iphepha. Wang Qing, umfundi othweswe iziqu, umbhali wokuqala wephepha, futhi umcwaningi wokuhlobanisa uYan Dongdong ngumbhali ohambisanayo. Umcwaningi uCou Aocheng, umcwaningi uWang Qiuxia futhi abanye banikeze ukuholwa emsebenzini wokucwaninga. Lo msebenzi wokucwaninga uxhaswe yiNational Natural Science Foundation of China kanye nohlelo lweNational Key Research and Development Program.
