Transgenic Bt cotton inhibited arbuscular mycorrhizal fungus differentiation and colonization
The present study investigated the impact of transgenic Bacillus thuringiensis (Bt) cotton on several aspects of arbuscular mycorrhizal (AM) fungus Funneliformis mosseae. The results showed that Bt cotton significantly inhibited spore germination and pre-symbiotic hyphal growth. The appressorium den...

| description | The present study investigated the impact of transgenic Bacillus thuringiensis (Bt) cotton on several aspects of arbuscular mycorrhizal (AM) fungus Funneliformis mosseae. The results showed that Bt cotton significantly inhibited spore germination and pre-symbiotic hyphal growth. The appressorium density, arbuscule frequency and colonization intensity in Bt roots were also decreased. The statistical analysis demonstrated that the transformation event resulted in the inhibition of hyphal development and colonization. The reduced interaction between AM fungi and plants could affect nutrient uptake and transportation in plant-fungus symbiosis. The mechanism might involve the direct toxicity of Bt toxins or the interference of signal perception between AM fungus and Bt cotton. |
