Mbewu zosamva tizilombo zitha kupha tizilombo ngati zidya.Kodi zidzakhudza anthu?

Kodi n'chifukwa chiyani mbewu zosamva tizilombo zimagonjetsedwa ndi tizilombo?Izi zimayamba ndi kutulukira kwa "jini yolimbana ndi tizilombo".Zaka zoposa 100 zapitazo, m’chigayo china m’tauni yaing’ono ya Thuringia, ku Germany, asayansi anapeza bakiteriya yokhala ndi mankhwala ophera tizilombo ndipo anaitcha kuti Bacillus thuringiensis dzina la tauniyo.Chifukwa chomwe Bacillus thuringiensis amatha kupha tizilombo ndi chifukwa ali ndi "mapuloteni olimbana ndi tizilombo a Bt" apadera.Puloteni iyi ya Bt yolimbana ndi tizilombo ndi yodziwika bwino kwambiri ndipo imatha kumangiriza "zolandilira zenizeni" m'matumbo a tizirombo tina (monga "lepidopteran" tizilombo toyambitsa matenda monga njenjete ndi agulugufe), zomwe zimapangitsa kuti tizilombo toyambitsa matenda tiwonongeke ndi kufa.Maselo am'mimba a anthu, ziweto ndi tizilombo tina (tizilombo tomwe si "Lepidopteran") alibe "ma receptor enieni" omwe amamanga puloteni iyi.Pambuyo polowa m'mimba, mapuloteni odana ndi tizilombo amatha kusungunuka ndi kuchepetsedwa, ndipo sangagwire ntchito.

Chifukwa mapuloteni odana ndi tizilombo a Bt alibe vuto kwa chilengedwe, anthu ndi nyama, mankhwala ophera tizilombo omwe ali nawo monga chigawo chachikulu chakhala chikugwiritsidwa ntchito bwino pa ulimi kwa zaka zoposa 80.Ndi chitukuko cha teknoloji ya transgenic, obereketsa alimi asintha jini ya "Bt insect-resistant protein" kukhala mbewu, zomwe zimapangitsa kuti mbewu zisakhalenso ndi tizilombo.Mapuloteni osamva tizilombo omwe amawononga tizilombo sangagwire ntchito mwa anthu atalowa m'matumbo a munthu.Kwa ife, mapuloteni olimbana ndi tizilombo amagayidwa ndikuwonongeka ndi thupi la munthu monga mapuloteni omwe ali mu mkaka, mapuloteni a nkhumba, ndi mapuloteni a zomera.Anthu ena amati monga chokoleti, chomwe anthu amachiwona ngati chakudya chokoma, koma chotenthedwa ndi agalu, mbewu zosamva tizilombo zimatengerapo mwayi pakusiyana kwa mitundu yotere, komwe kulinso maziko a sayansi.
