“…Articles in this group also stated that certain effects such as gene flow or nontarget effects might have (harmful) consequences for the environment in general. These articles discussed the impact on agricultural biodiversity in general (e.g., Gura 2001;Hails 2002;Kotschi 2008) or pointed out that farmland biodiversity might be increased by the use of herbicide resistant crops (e.g., Madsen and Sandøe 2001).…”

The use of genetically modified plants in agriculture (GM crops) is controversially discussed in academic publications. Important issues are whether the release of GM crops is beneficial or harmful for the environment and therefore acceptable, and whether the modification of plants is ethically permissible per se. This study provides a comprehensive overview of the moral reasoning on the use of GM crops expressed in academic publications from 1975 to 2008. Environmental ethical aspects in the publications were investigated. Overall, 113 articles from 15 ecology, environmental ethics, and multidisciplinary science journals were systematically reviewed. Three types of moral concerns were used to structure the normative statements, moral notions, and moral issues found in the articles: concerns addressing consequences of the use of GM crops, concerns addressing the act (the technique itself), and concerns addressing the virtues of an actor. Articles addressing consequences (84%) dealt with general ecological and risk concerns or discussed specific ecological issues about the use of GM crops. Articles addressing the act (57%) dealt with the value of naturalness, the value of biotic entities, and conceptual reductionism, whereas articles addressing the actor (43%) dealt with virtues related to the handling of risks and the application of GM crops. The results of this study may help to structure the academic debate and contribute to a better understanding of moral concerns that are associated with the key aspects of the ethical theories of consequentialism, deontology, and virtue ethics.

In a previous study, an HBsAg gene-bearing transgenic tomato line was made available and it exhibited notable physiological alterations compared with the non-transgenic tomato (control). In particular, leaves of the transgenic plants were fleshy and dark. We hypothesized that a change in leaf proteins of the transgenic plants account for the observed phenotypes. In this study, total protein content in leaves of the transgenic plants was analyzed by 2-dimensional difference gel electrophoresis. A total number of 700 protein spots were detected on silver-stained gels, of which 368 protein spots were matched between the control and sample gels. Among these matched proteins, the expression levels of 122 proteins in the transgenic plants were upregulated while those of the rest were downregulated. In addition, 25 abundant proteins (value ratio > 2.0) on silver-stained gels were analyzed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Sixteen differentially expressed proteins were identified, of which 13 were predicted to be involved in cell division, energy metabolism, protein synthesis and processing. The possible roles of these proteins in the transgenic tomato strain have been discussed. Taken together, our data indicate that significant alterations in protein expression occur in transgenic tomatoes bearing the HBsAg gene. Our findings will help broaden our knowledge of the mechanism by which exogenously expressed genes lead to phenotypic alterations in transgenic plants.
