Abstract

The development and use of transgenic plants has steadily increased, but there are still little data about the responses of soil microorganisms to these genetic modifications. We utilized a greenhouse trial approach to evaluate the effects of altered stem lignin in trembling aspen (Populus tremuloides) on soil microbial communities in three soils which differed in their chemical and physical properties; they included a sandy loam (CO-Colorado), a silt loam (KS-Kansas), and a clay loam (TX-Texas). Three transgenic aspen lines were developed from a natural clone common to the Great Lakes region of North America.
