E pepehi nā mea kanu i pale ʻia i nā pepeke i hoʻololi ʻia i ka genetics i nā pepeke inā ʻai lākou iā lākou. E hoʻopilikia anei ia i nā kānaka?

No ke aha i kūpaʻa ai nā mea kanu i hoʻololi ʻia i nā pepeke i nā pepeke? Hoʻomaka kēia me ka ʻike ʻia ʻana o ka "gene protein insect-resistant". Ma mua o 100 mau makahiki i hala aku nei, ma kahi wili ma ke kūlanakauhale liʻiliʻi o Thuringia, Kelemānia, ua ʻike nā kānaka ʻepekema i kahi bacteria me nā hana insecticidal a kapa ʻia ʻo Bacillus thuringiensis ma hope o ke kūlanakauhale. ʻO ke kumu e hiki ai iā Bacillus thuringiensis ke pepehi i nā pepeke no ka mea aia i loko kahi "protein Bt insect-resistant" kūikawā. He kikoʻī loa kēia protein Bt anti-insect a hiki ke hoʻopaʻa wale i nā "mea loaʻa kikoʻī" i loko o ka ʻōpū o kekahi mau mea ʻino (e like me nā mea ʻino "lepidopteran" e like me nā pulelehua a me nā pulelehua), e hoʻoulu ai i nā mea ʻino e perforate a make. ʻAʻohe "mea loaʻa kikoʻī" o nā cell gastrointestinal o ke kanaka, nā holoholona a me nā pepeke ʻē aʻe (nā pepeke ʻaʻole "Lepidopteran") e hoʻopaʻa i kēia protein. Ma hope o ke komo ʻana i loko o ke ala ʻai, hiki ke ʻeli wale ʻia a hoʻohaʻahaʻa ʻia ka protein anti-insect, a ʻaʻole e hana.

No ka mea, ʻaʻohe mea ʻino o ka protein Bt anti-insect i ke kaiapuni, nā kānaka a me nā holoholona, ​​ua hoʻohana palekana ʻia nā bio-insecticides me ia ma ke ʻano he ʻāpana nui i ka hana mahiʻai no nā makahiki he 80 a ʻoi. Me ka hoʻomohala ʻana o ka ʻenehana transgenic, ua hoʻoili nā mea kanu mahiʻai i ka gene "Bt insect-resistant protein" i loko o nā mea kanu, e hana ana i nā mea kanu i kū i nā pepeke. ʻAʻole e hana nā protein pale pepeke e hana ana ma nā mea ʻino i nā kānaka ma hope o ke komo ʻana i loko o ke ala ʻai kanaka. No mākou, ua ʻeli ʻia a hoʻohaʻahaʻa ʻia ka protein pale pepeke e ke kino kanaka e like me ka protein i loko o ka waiū, ka protein i loko o ka puaʻa, a me ka protein i loko o nā mea kanu. Wahi a kekahi poʻe e like me ke kokoleka, kahi i manaʻo ʻia he mea ʻono e nā kānaka, akā ua make ʻia e nā ʻīlio, hoʻohana nā mea kanu pale pepeke i hoʻololi ʻia i ka genetically i kēlā mau ʻokoʻa ʻano, ʻo ia hoʻi ke ʻano o ka ʻepekema.
