Bradyrhizobium japonicum est capabl

Bradyrhizobium japonicum est capable d’induire sur les racines du soja la formation de nodules dans lesquels elle fixe l’azote atmosphérique, en symbiose avec la plante. L’exposition du soja transgénique à l’herbicide induit l’inhibition de l’enzyme à activité nitrogénase de la bactérie, l’EPSPS. Cette exposition entraîne l’inhibition de la croissance de la bactérie ainsi que sa mort à des concentrations élevées. Le suivi de soja transgénique auquel on a appliqué de l’herbicide montre que le potentiel de fixation de N2 est réduit et retardé (13).

Ainsi, les cultures transgéniques résistantes aux insectes et celles tolérantes aux herbicides sont toxiques par :

∙ Impact direct : l’ OGM établit un lien fonctionnel avec l’organisme touché (insecte herbivore cible),
∙ Impact indirect : l’OGM exerce son influence par l’intermédiaire d’un organisme tiers, sur un autre organisme (insecte pollinisateur, bactérie symbionte, prédateur de l’insecte herbivore cible…etc).

Bradyrhizobium japonicum is able to induce on the roots of soybean nodulation in which it fixes atmospheric nitrogen, in symbiosis with the plant. Transgenic soybean herbicide exposure induced inhibition of nitrogenase activity of the bacterium, the EPSPS enzyme. This exposure causes the inhibition of the growth of the bacteria as well as his death in high concentrations. Monitoring of transgenic soybeans which have applied herbicide shows that the potential of N2 fixation is reduced and delayed (13)

so, insect-resistant transgenic crops tolerant to the herbicides are toxic by:

∙ direct Impact: the GMO establishes a functional link with the affected Organization (herbivorous insect target),
∙ indirect Impact: the GMO exerts its influence through a third body on another body (insect Pollinator, bacterial symbiont, predator of the herbivorous insect target... etc.).

Exposure of transgenic soybean herbicide induced inhibition of the enzyme nitrogenase activity of the bacteria, the EPSPS. This exposure results in inhibition of the growth of the bacterium and death in high concentrations. Monitoring of transgenic soybean which was applied herbicide shows that the potential of N2 fixation is reduced and delayed (13). Thus, transgenic insect-resistant crops and herbicide tolerant ones are toxic: ∙ Direct impact: the GMO establishes a functional relationship with the affected organization (insect herbivore target) ∙ Indirect Impact: OGM exerts its influence through a third party, on another organism (insect pollinator, symbiont bacteria, predator insect herbivore target ... etc).

Bradyrhizobium japonicum is capable of misleading on the roots of soybean nodule formation in which she fixed atmospheric nitrogen, in symbiosis with the plant. The exposure of the transgenic soybeans to the herbicide induces the inhibition of the enzyme to nitrogenase activity of the bacteria, the EPSPS.This exposure resulted in the inhibition of growth of the bacterium as well as his death in high concentrations. The monitoring of transgenic soybeans which has been applied to the herbicide shows that the potential of fixing of N2 is reduced and delayed (13) .

thus, transgenic crops resistant to insects and those tolerant to herbicides are toxic by:

∙ direct Impact:The GMOS establishes a functional link with the key agency (insect herbivore target) ,
∙ indirect Impact: the GMO exerts its influence through a third party organization, on another body (insect pollinator, bacterium symbionte, predator of the insect herbivore target ... etc) .
