Abstract
Deleterious effects of transgenic plants on soils represent an often ex-
pressed concern, which has catalyzed numerous studies in the recent past.
In this literature review, studies addressing this question have been com-
piled. A total of 60 studies has been found, and their findings as well as their
analytical approaches are summarized. These studies analyzed the effects
of seven different types of genetically engineered traits, i.e., herbicide toler-
ance, insect resistance, virus resistance, proteinase inhibitors, antimicrobial
activity, environmental application, and biomolecule production. Sixteen
genetically engineered plant species were investigated in these studies
including corn, canola, soybean, cotton, potato, tobacco, alfalfa, wheat, rice,
tomato, papaya, aubergine, and silver birch. Many of these plants and traits
have not been commercialized and represent experimental model systems.
Effects on soil microbial characteristics have been described in various stud-
ies, indicating the sensitivity and feasibility of the analytical approaches
applied. However, classification of the observed effects into acceptable and
unacceptable ones has not been possible so far. Establishment of validated
indicators for adverse effects represents a scientific challenge for the near
future, and will assist risk assessment and regulation of transgenic plants
commercially released to the field.
