Do GM crops affect the nodule formation (mainly N fixing bacteria) or fungal activity in leguminous or non-leguminous crop.
It depends on type of the considered GM plant.
Targeted genetic traits for plant nutrition can improve assimilation of N from air. See the paper "Impact of Genetically Modified Crops and Their Management on Soil Microbially Mediated Plant Nutrient Transformations" by P. P. Motavalli, R. J. Kremer, M. Fang, and N. E. Means (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.503.4674&rep=rep1&type=pdf.)
1. It depends on what kind of GM plants you have. If the transgenesis of your GM plants involve in 'overexpression' or ' knockout' of the nodule-specific genes encoded by the host plant, the so-called nodulin genes, you may get GM plants with abnormal nodule formation.
More info on nodulin genes: http://www.nature.com/nature/journal/v323/n6088/abs/323564a0.html
2. You may also un-purposely knock out an essential nodulin gene by genetically transforming of, for example, a GUS gene due to random insertion. This may also cause the abnormal formation of nodules.
if the GM is not targeted, then it will not. We have millions of Acres of Soy, with no impact on nodulation, across geographies.
Dose Transgenic crops affect the symbiotic relationship in leguminous or non-leguminous crops?
