I kēia mau lā, ua paʻi ʻia ka Soil Pest Control Innovation Team o ka Institute of Plant Protection, Chinese Academy of Agricultural Science, ma ka puke pai honua kaulana "Journal of Hazardous Materials" i kapa ʻia ʻo "Transcriptome e hōʻike i ka ʻokoʻa o ka dimethyl disulfide ma o ka hoʻopili ʻana a me ka fumigation ma Meloidogyne. incognita ma o ke kahawai calcium -mediated oxidative phosphorylation” pepa noiʻi. Hoʻopili kēia pepa i nā hana biochemical a me ka molekala o ka ʻokoʻa o ka hana olaola o ka fumigant dimethyl disulfide lepo.(DMDS)e kū'ē i nā nematodes root-knot ma lalo o ʻelua mau ʻano hana like ʻole: ka pepehi kanaka a me ka fumigation, a hāʻawi i ka ʻike no ka noi ʻepekema a me ka pono o ka fumigant DMDS hou manaʻo hou.
ʻO ka pale ʻana a me ka mālama ʻana i nā maʻi nematode root-knot i ka lepo he pilikia honua, a ua hana maikaʻi nā nemicide kemika i ka pale ʻana a me ka mālama ʻana i nā maʻi nematode hua. Hoʻohana nui ʻia nā fumigants lepo no ka mālama ʻana i nā pests lepo ma muli o ko lākou hopena paʻa a me ka hoʻohana pono. ʻO DMDS kahi ʻano hou o ka fumigant lepo, he ʻoluʻolu kaiapuni a loaʻa nā manaʻo hoʻohana ākea. No ka mea aia kekahi mau ʻokoʻa i ke ʻano o ka hana ʻana o nā fumigants a me nā mea hoʻopili kuʻuna ma luna o nā mea ola kino, ua ʻimi kēia noiʻi i nā hopena kikoʻī o DMDS ma nā nematodes mai nā manaʻo ʻelua o ka pepehi kanaka a me ka fumigation, e lawe ana i ka ʻokoʻa o ka ʻona o DMDS i nā nematodes ma ke ʻano he wahi komo. Mechanism.
Ua hōʻike piha ʻia ke aʻo ʻana i ke komo ʻana o ka mea hana i ka nematode root-knot nematode ma nā ʻano like ʻole ma lalo o nā ʻano hana ʻelua: fumigation a me ka hoʻopili ʻana i ka pepehi kanaka, hōʻino i ke ʻano o nā ʻāpana like ʻole o ka nematode, hoʻopilikia i nā kahawai ion calcium i nā ʻano like ʻole, a hoʻopilikia. nā paʻakikī like ʻole o ka phosphorylation oxidative i ka hanu. . Ma ke ʻano pepehi kanaka, komo pololei ʻo DMDS i loko o ke kino o ka nematode ma o ka paia o ke kino, hoʻopau i ka paia o ke kino a me ka ʻiʻo physiological structure o ka nematode, hana ma ke ʻano he uncoupling agent, hoʻopilikia i ka ATP synthase, a hoʻoulu i ka hanu o ka nematode. Ma ke ʻano fumigation, komo ʻo DMDS i ke kino nematode ma o ke kaʻina olfactory perception-oxygen exchange kaʻina, a hana hope ma ka respiratory electron transport chain complex IV or complex I, superimposing me ka pōʻino oxidative, e make ai ka nematode. Kōkua kēia haʻawina i ke alakaʻi ʻana i ka hoʻohana ʻana i nā fumigant me ka palekana, ʻepekema a maikaʻi hoʻi, a hoʻonui pū i ke kumumanaʻo o nā hana hana fumigant.
ʻO ka Institute of Plant Protection of the Chinese Academy of Agricultural Science ka ʻāpana i hoʻopau i ka pepa. ʻO Wang Qing, he haumāna puka, ʻo ia ka mea kākau mua o ka pepa, a ʻo Yan Dongdong ka mea noiʻi pili. ʻO ka mea noiʻi ʻo Cao Aocheng, ka mea noiʻi ʻo Wang Qiuxia a me nā mea ʻē aʻe i alakaʻi i ka hana noiʻi. Ua kākoʻo ʻia kēia hana noiʻi e ka National Natural Science Foundation o Kina a me ka National Key Research and Development Program.
