Marginal impact of cropping BADH transgenic maize BZ-136 on chemical property, enzyme activity, and bacterial community diversity of rhizosphere soil

Aims Transgenic betaine aldehyde dehydrogenase (BADH) maize that overaccumulates glycine betaine (GB) is developed to enhance tolerance to salt stress, while the ecological risk of cropping BADH transgenic maize BZ-136 on soil properties and rhizosphere microorganisms is ambiguous.
