Bacterial diversity in rhizospheres of nontransgenic and transgenic corn

Appl Environ Microbiol. 2005 Jul;71(7):4132-6. doi: 10.1128/AEM.71.7.4132-4136.2005.

Abstract

Bacterial diversity in transgenic and nontransgenic corn rhizospheres was determined. In greenhouse and field studies, metabolic profiling and molecular analysis of 16S rRNAs differentiated bacterial communities among soil textures but not between corn varieties. We conclude that bacteria in corn rhizospheres are affected more by soil texture than by cultivation of transgenic varieties.
