  2. Natural Mutation and Genetic Engineering (transfer of genes over natural barriers) Have the same molecular processes Arber, W. (2010) Genetic engineering compared to natural genetic variations. New Biotechnology, 27, 5, pp 517-521 http://www.ask-force.org/web/Vatican-PAS-Studyweek-Elsevier-publ-20101130/Arber-Werner-PAS-Genetic-Engineering-Compared-20101130-publ.pdf

  3. Interestingly, naturally occurring molecular evolution, i.e. the spontaneous generation of genetic variants has been seen to follow exactly the same three strategies as those used in genetic engineering14. These three strategies are (after W. Arber, Nobel Laureate 1978) (a) small local changes in the nucleotide sequences, (b) internal reshuffling of genomic DNA segments, and (c) acquisition of usually rather small segments of DNA from another type of organism by horizontal gene transfer. Arber, W. (2002) Roots, strategies and prospects of functional genomics. Current Science, 83, 7, pp 826-828 http://www.botanischergarten.ch/Mutations/Arber-Comparison-2002.pdf Arber, W.

  4. Fig. 1 Synoptical presentation of major elements of the theory of molecular evolution. A number of specific mechanisms contribute, each with its own characteristics to the four groups of mechanisms of genetic variation listed. Each of the specific mechanisms follows one (and sometimes more than one) of the three principal, qualitatively different strategies of genetic variation. Arber, W. (2002) Roots, strategies and prospects of functional genomics. Current Science, 83, 7, pp 826-828 http://www.botanischergarten.ch/Mutations/Arber-Comparison-2002.pdf Arber, W.

  5. However, there is a principal difference between the procedures of genetic engineering and those serving in nature for biological evolution. While the genetic engineer pre-reflects his alteration and verifies its results, nature places its genetic variations more randomly and largely independent of an identified goal. After ca. 10 years of testing the GM crops are brought to the field by millions in a few years Arber, W. (2002) Roots, strategies and prospects of functional genomics.

  6. Changes in gene expression in MON810 vs. near-isogenic maize lines Aristis Bt vs. Aristis and PR33P67 vs. PR33P66. Each point represents one gene in the maize Affymetrix microarray. The log odds for differential expression of all genes, estimated from the RMA analysis of the data were plotted against the estimated log2 fold changes. Thus, a twofold increase or decrease in the level of a given transcript corresponds to 1 or -1, respectively. Bold, sequences further analyzed by real-time RT-PCR. From (Coll et al., 2008) The Graph in fig. 2 demonstrates clearly that genomic variability can be more substantial among the non-transgenic traits (right) in the analyzed traits than in a comparison between GM- and non-GM maize traits (left).

  8. Comparative microarray analysis demonstrates, that transcriptomic disturbances are more important in conventional crops when compared to isolines of transgenic crops Barros, E., Lezar, S., Anttonen, M.J., Dijk, J.P.v., Röhlig, R.M., Kok, E.J., & Engel, K.-H. 2010 Comparison of two GM maize varieties with a near-isogenic non-GM variety using transcriptomics, proteomics and metabolomics.

Dots represent the normalized relative expression level of each arrayed gene for the transcriptome comparisons described. Dots in black represent statistically significant, differentially expressed genes (DEG) at an arbitrary cut off > 1.5. The inner line on each graph represents no change in expression. The offset dashed lines are set at a relative expression cut-off of twofold. In the adjacent coloured bar (rectangle on the far right of the figure), the vertical axis represents relative gene expression levels: reds indicate overexpression, yellows average expression, and greens under-expression. Values are expressed as n-fold changes. The horizontal axis of this bar represents the degree to which data can be trusted: dark or unsaturated colour represents low trust and bright or saturated colour represents high trust.

  12. Differences observed in gene expression in the endosperm between conventionally bred material were much larger in comparison to differences between transgenic and untransformed lines exhibiting the same complements of gluten subunits. These results suggest that the presence of the transgenes did not significantly alter gene expression and that, at this level of investigation, transgenic plants could be considered substantially equivalent to untransformed parental lines.

  15. “The close similarity of the up- and downstream regions with the corresponding regions in P. palustris excludes all suggestions that PgiC2 is not a HGT but the result of a duplication within the F. ovina lineage. The small size of the genetic material transferred, the complex nature of the PgiC2 locus, and the associated fragment with transposition associated properties suggest that the horizontal transfer occurred via a vector and not via illegitimate pollination.” Vallenback, P., Ghatnekar, L., & Bengtsson, B.O.

  16. Development time and frequency of transposition differ in mutations caused by the insertion of different defective Spm elements. If transposition takes place late in the development, the clones of revertent cells are small and therefore so are the pigmented spots (a) . If transposition takes place at about the same time but at a lower frequency, there are fewer such clones and fewer spots (b). If the transposition that resores gene function takes place earlier, the revertant clones and the spots of the pigmented tissue are larger (c). From (Fedoroff, 1984). Fedoroff, N.V.

  20. Kogel et al. 2010: In summary, our results substantially extend observations that cultivar-specific differences in transcriptome and metabolome greatly exceed effects caused by transgene expression. Furthermore, we provide evidence that, (i) the impact of a low number of alleles on the global transcript and metabolite profile is stronger than transgene expression Kogel, K.-H., Voll, L.M., Schaefer, P., Jansen, C., Wu, Y., Langen, G., Imani, J., Hofmann, J.r., Schmiedl, A., Sonnewald, S., von Wettstein, D., Cook, R.J., & Sonnewald, U.

  21. Old, untargeted methods in former decades: • Colchicin application: it is a toxin enhancing the number of mutations, doubling chromosome numbers and produce haploid (one chromosome set) for breeding UNCONTROLLABLE EFFECT • Radiation mutation breeding: hundreds of cases, including Durum Wheat for pasta. All those methods produce uncontrolled changes in genomes, more transcriptomic disturbance than genetic engineering. • Primarily uncontrollable effects, later eliminated through repair mechanisms and breeders selection

  23. What Conclusions Can Be Drawn Regarding the Substantial Equivalence Concept? It is important to keep in mind that the standard proposed by the OECD/Food and Agriculture Organization of the United Nations/World Health Organization was substantial equivalence rather than total equivalence and that there is no specific statistical or biological basis to define “substantial” (Hoekenga, 2008). In other words, no “limits of concern” have been defined regarding differences. In addition, plant composition is usually variable even within a single variety. Pairwise differences between a GE line and its comparator are usually less than natural variability. Furthermore, near isogenic lines differ by a number of alleles, which could explain a number of differences attributed to transgenesis. Thus, the substantial equivalence concept cannot provide more than a guiding framework for evaluation. Ricroch, A.E., Berge, J.B., & Kuntz, M. (2011) Evaluation of genetically engineered crops using transcriptomic, proteomic and metabolomic profiling techniques. Plant Physiology, preview February 24, 2011, pp 26 http://www.plantphysiol.org/cgi/content/abstract/pp.111.173609v1 AND http://www.ask-force.org/web/Food/Ricroch-Evaluation-GE-crops-omics-2011.pdf AND http://www.ask-force.org/web/Genomics/Ricroch-Evaluation-GE-Crops-Omics-def-2011.pdf AND http://www.ask-force.org/web/Food/Ricroch-Evaluation-GE-crops-omics-Suppl-T-II-2011.pdf AND http://www.ask-force.org/web/Food/Ricroch-Evaluation-GE-crops-omics-Suppl-TI-2011.pdf AND http://www.ask-force.org/web/Food/Ricroch-Evaluation-GE-crops-omics-Suppl.-References-S2-2011.pdf AND http://www.ask-force.org/web/Food/Ricroch-Evaluation-GE-crops-omics-Suppl.-References-S4-2011.pdf

  24. Nevertheless, the experience acquired after 15 years of GE crop commercialization has comforted the validity of this framework [Substantial Equivalence]. However, considering the highly polarized views on GE crops, it is important to notice that the opinions expressed previously by food safety agencies (i.e. general “equivalence” of authorized GE crops with non-GE comparators) have now been independently corroborated at the transcriptomic, proteomic, and metabolomic levels by recently published omic comparisons (Table I). None of the published omic assessments has raised new safety concerns about marketed GE cultivars. Ricroch, A.E., Berge, J.B., & Kuntz, M.

  27. Reuters, May 10, 2010 UN's International Atomic Energy Agency since 1963, 2,252 new plant varieties, including Italian durum wheat, have been created using radioactive substances such as cobalt and X-rays. 70% of the crops under cultivation worldwide are radiation mutation varieties Charles Margulis of Greenpeace USA: "But now they tell us that scientists have been artificially hybridizing plants since the 1960s.That's, like, really uncool."

  28. Radiation Mutation old to plant breeders, new to Activists: caused unjustified panics ca. 1960 Activists, supported by Jane Rissler, called for a ban, since those irradiated varieties have never been tested for food safety, which would have wiped out 70% of the food products on shelfs. Jane Rissler: “Compared to these plants, genetically modified food is about as dangerous as a one-legged man in an ass-kicking contest.” But excellent repair mechanisms working like zippers are reducing radiation damage considerably And worldwide there has been no correlation established between radiation mutation and negagtive food safety facts.

  41. Mixed message if you compare the impact of modern agriculture with organic farming: there are sometimes coming good results from organic farming, but also modern agriculture has its positive impact

  45. Scheme to visualize the hierarchical sampling design of: (a) 16 paired landscapes (coldspots in black and hotspots in grey) in two regions in England. Each landscape pair within a region forms a cluster, which is shown by the shading pattern. (b) Schematic view of a coldspot and hotspot landscape with low or high amount of organic land (grey shading). Each landscape contains one organic (grey circle) and one conventional farm (white circle) with three arable and grass fields (dark and light grey rectangles). (c) Farmland biodiversity components were surveyed on each field at nine sampling stations (grey rectangles): three in the margin (M), three in the edge (E) and three in the centre (C). Sampling design within a sampling station (magnified) using the hot mustard method for earthworms (grey circle), three 1-m2 quadrats for plants, nine Vortis suctions for epigeal arthropods (white circles) and a triplicate pantrap for pollinators. Note: Earthworms were sampled only in the centre and edge location and in 2008 the sampling effort for earthworms was increased from three sampling stations to five. Pantraps were exposed only in field centres and margins. Transect walks for butterflies and birds are not shown. Gabriel, D., Sait, S.M., Hodgson, J.A., Schmutz, U., Kunin, W.E., & Benton, T.G.

  46. birds and solitary bees are often better taken care of by conventional agriculture Distribution of different measures describing farmland birds across organic and conventional farms in coldspot (black) and hotspot (grey) landscapes. (g) Ordination of farmland bird species (black dots) and corvids (grey triangles). Means + SEM per farm and survey, n = 190; number of: (a) farmland bird species, (b) farmland bird specialist species, (c) farmland bird generalist species; (d) Shannon Index; (e) number of farmland birds excluding jackdaw and rook and (f) number of corvids (jackdaw, rook, jay and magpie) per farm and survey. Geometric means are shown for abundance data. The effect of farm management does not depend on which measure is used. See Appendix S1c for additional details. although management effects on biodiversity were quite consistent for some species groups, such as plants and butterflies, for others such as birds and solitary bees, the effects (and effect sizes) varied considerably between regions.
