Ibyo wamenya ku bimera byahinduriwe uturemangingo sano,OGM, byamaze kugezwa mu Rwanda

Inkuru Virunga Today ikesha ikinyamakuru Kigali Today iremexa ko kuri uyu wa 17,/03/2026, Ikigo cy’Igihugu cyita ku Buhinzi n’Ubworozi (RAB) cyakoze igikorwa cyo gusogongera ubwoko bushya bw’imbuto z’imyumbati zimaze igihe zikorerwaho ubushakashatsi, zikaba ari imbuto zongerewe ubudahangarwa, bituma zitarwara kabore, indwara ifata imyumbati ikabora, abahinzi bagahomba.

Nk’uko bikomeza byemezwa na Kigali Today ngo Kugira ngo izi mbuto ziboneke, hifashishijwe ubushakashatsi bwanyuze muri gahunda ya Leta yo kuvugurura imbuto biciye mu ikoranabuhanga izwi nka Rwanda AgriBiotech Program (RABP-CMP) ku bufatanye na RAB ndetse n’Ikigo nyafurika giteza imbere ikoranabuhanga mu Buhinzi (AATF).

Muri iyi nkuru twifuje kugaruka ku bihingwa byahinduriwe Uturemangingo sano, OGM bukoresha muri technique ya biotechnologie ari nayo yakoreshejwe ngo haboneka izi mbuto z’ibijumba.

1.Tekiniki ya Biotechn

ADN (Acide Désoxyribonucléique) ni “umwirondoro w’ubuzima” w’ibihingwa, kuko ari wo utuma imyaka igira ubuziranenge, umusaruro, n’ubushobozi bwo kwihanganira ibidukikije. Mu buhinzi, ADN igena ibiranga nk’uburyo imyaka irwanya indwara, uburyo ikura, ndetse n’ibirimo intungamubiri.

Nahi Ubuhinzi bwa biotech burangwa no gukoresha ikoranabuhanga ryo guhindura cyangwa guhitamo uturemangingo ndagasano (ADN) mu bihingwa n’amatungo kugira ngo byongere umusaruro, birwanye indwara n’ibyonnyi, kandi bihangane n’imihindagurikire y’ikirere. Ibyo binyabuzima bishya nibyo bita : OGM: Organisme Génétiquement Modifié.

Techniques za Biotecn

1. Transgenèse (ikunze gukoreshwa cyane)
Ibisobanuro: Kongeramo génes nshya z’amahanga mu gihingwa kugira ngo gihabwe ubushobozi bushya.
Etapes:
1. Gutoranya génes zifite akamaro (nko kurwanya udukoko cyangwa kongera intungamubiri).
2. Gushyira génes mu gihingwa hakoreshejwe Agrobacterium tumefaciens (bacterie ikoreshwa mu gutwara génes mu gihingwa) cyangwa gene gun (uburyo bwo kurasa ADN mu turemangingo tw’igihingwa).
3. Kurema imbuto nshya: Igihingwa gishyirwamo transgene gikura gifite ubushobozi bushya.
4. Igerageza mu mirima yihariye kugira ngo harebwe imikorere yacyo n’umutekano ku bidukikije.
5. Kugezwa ku bahinzi mu buryo bwemewe n’amategeko.

Aho ikunze gukoreshwa:

2. Mutagenèse
Ibisobanuro: Guhindura cyangwa gukuramo génes ziri mu gihingwa ubwacyo, hakoreshejwe imirasire (radiation – imirasire ikomeye nka gamma rays), imiti (chemical mutagens – imiti isandaza ADN), cyangwa ikoranabuhanga rigezweho nka CRISPR-Cas9 (uburyo bwo guca ADN ahantu hagenwe neza).
Etapes:
1. Kumenya génes zitera ibibazo cyangwa zidafite akamaro.
2. Gushyira igihingwa mu mutagen (radiation/imiti) cyangwa gukoresha CRISPR-Cas9 kugira ngo génes ikurwemo cyangwa ihagarikwe gukora.
3. Kurema imbuto nshya: Igihingwa gikura gifite impinduka nshya.
4. Igerageza mu mirima kugira ngo harebwe imikorere yacyo.
5. Kugezwa ku bahinzi mu buryo bwemewe.

Mi ryari ikoreshwa
Mutagenèse ikunze gukoreshwa mu buhinzi n’ubushakashatsi kugira ngo habeho impinduka mu génes z’ibihingwa, bigamije kongera umusaruro, guhangana n’indwara n’ibyonnyi, no gutuma bihangana n’imihindagurikire y’ikirere. Abashakashatsi bayikoresha bashaka guha igihingwa ubushobozi bushya cyangwa gukuraho génes zitera ibibazo.

Aho mutagenèse ikunze gukoreshwa
– Mu ngano (wheat): Guhanga imbuto zihangana n’izuba cyangwa imvura nke.
– Mu kasava (cassava): Kugabanya cyanide iri mu gihingwa kugira ngo kiboneke nk’ikiribwa gitekanye.
– Mu nyanya (tomato): Gukuramo génes zituma zibora vuba, bigatuma zibika igihe kirekire.
– Mu mpano z’indimu n’imbuto: Guhanga imbuto zifite uburyo bwo kurwanya indwara ziterwa na fungi.
– Mu mpano z’ibinyampeke: Kongera intungamubiri (biofortification) nko mu muceri cyangwa ibigori.

Icyo abashakashatsi baba bifuza ku kinyabuzima
– Kongera genetic diversity: Gutuma habaho ubwoko bushya bw’ibihingwa bifite imiterere itandukanye, bikagabanya ikibazo cyo kubura imbuto zitandukanye.
– Kurwanya biotic stress: Kugabanya igihombo giterwa n’indwara n’ibyonnyi.
– Kurwanya abiotic stress: Gutuma ibihingwa bihangana n’izuba, imvura nke, cyangwa ubutaka butari bwiza.
– Kongera intungamubiri: Guhanga ibihingwa bifite vitamini cyangwa minerali nyinshi kurusha ibisanzwe.
– Kugabanya uburozi: Gukuramo génes zitera uburozi mu bihingwa bimwe (nko mu kasava).

Impungenge
– Impinduka random: Iyo hifashishijwe imirasire cyangwa imiti, impinduka ziba zidasobanutse neza, bigasaba gutoranya imbuto nyinshi.
– Umutekano ku bidukikije: Hari impaka ku ngaruka z’igihe kirekire ku bidukikije.
– Umutekano ku buzima: Nubwo mutagenèse ikunze gutanga imbuto zizewe, hakenewe kugenzurwa bikomeye.

Ubwiza bwayo: Iha ubushobozi bwo gukuraho génes mbi cyangwa guhindura ADN neza, cyane cyane iyo hifashishijwe CRISPR-Cas9 (precision – guhindura neza ku gène runaka). Ariko mutagenèse ya radiation ikora mu buryo random (impinduka zidasobanutse hose mu ADN), bigasaba gutoranya imbuto nyinshi.

3. Cisgenèse
Ibisobanuro: Kongeramo génes ziva mu gihingwa cya hafi (same species – igihingwa kimwe cyangwa cross-compatible species – igihingwa gihuza génes), bityo nta ADN y’amahanga ikoreshwa.
Etapes:
1. Gutoranya génes zifite akamaro mu gihingwa cya hafi.
2. Gushyira génes mu gihingwa hakoreshejwe uburyo bwa biotech (Agrobacterium cyangwa gene gun nk’uko bisobanurwa hejuru).
3. Kurema imbuto nshya: Igihingwa gishyirwamo génes gikura gifite ubushobozi bushya.
4. Igerageza mu mirima kugira ngo harebwe imikorere yacyo.
5. Kugezwa ku bahinzi mu buryo bwemewe.

Aho ikunze gukoreshwa:
