The feeding ecology of earthworms – A review (2007, background): “, 1999), and the interactions between earthworms and transgenic plants or their litter (Saxena and Stotzky, 2001; Zwahlen et al., 2003).”
Effect of Bt Corn for Corn Rootworm Control on Nontarget Soil Microarthropods and Nematodes (2003, background): “However, Saxena and Stotzky (2001) found that the Bt toxin (Cry1Ab) released from root exudates and biomass of Bt corn had no apparent effect on earthworms, nematodes, protozoa, bacteria, and fungi in soil.”
Field decomposition of transgenic Bt maize residue and the impact on non-target soil invertebrates (2007, methodology): “During plant growth Cry1Ab is released by roots and persists at least until the occurrence of the first frost (Saxena et al. 1999; Saxena and Stotzky 2000; Saxena and Stotzky 2001b).”
Changes of Bt Toxin in the Rhizosphere of Transgenic Bt Cotton and its Influence on Soil Functional Bacteria (2005, background): “Bt toxin produced by Bt corn had no long-term effects on total numbers of culturable bacteria, fungi, protozoa and nematodes ( Saxena & Stotzky 2001 ).”
A Comparison of Soil Microbial Community Structure, Protozoa and Nematodes in Field Plots of Conventional and Genetically Modified Maize Expressing the Bacillus thuringiens is CryIAb Toxin (2005, background): “, 2000) but no effects of Bt maize on populations of earthworms, nematodes, protozoa or microbes (CryIAb; Saxena and Stotsky, 2001) or any direct effects of the consumption of Bt crops or exposure to Bt toxin on a soil mite and collembolan (CryIAb, CryIAc, CryIIA, CryIIIA; Sims and Martin, 1997; Yu ”
Transgenic Bt cotton has no apparent effect on enzymatic activities or functional diversity of microbial communities in rhizosphere soil (2006, positive): “For Bt corn, it was possibly because a significantly higher content of lignin compared with non-Bt corn (Saxena and Stotzky 2001b), but for Bt canola, cotton, potato, rice, and tobacco, the reason was unclear (Stotzky 2004), thus, it should be more cautious to give a conclusion on Bt crop’s…”
Transgenic Bt rice does not affect enzyme activities and microbial composition in the rhizosphere during crop development (2008, background): “With the development and use of transgenic technology, the effect of transgenic plants on the environment has become an issue of public concern (Li et al., 1996; Saxena and Stotsky, 2001; Saxena et al., 2002).”
Effects of transgenic plants on soil microorganisms (2005, methodology): “…there were no significant differences in the CFUs of culturable bacteria and fungi after 40 days between rhizosphere soils of transgenic corn containing the Cry1Ab gene and the non-transgenic corn or after 45 days between soils amended with biomass of the two corn lines (Saxena and Stotzky, 2001).”
Detectability of Coleopteran-specific Cry3Bb1 Protein in Soil and Its Effect on Nontarget Surface and Below-Ground Arthropods (2005, background): “Saxena and Stotzky (2001) also found that root exudates from Bt corn (Cry1Ab) had no observable effect on earthworms, nematodes, protozoa, fungi, or bacteria.”
Current status and environmental impact of transgenic forest trees (2004, background): “The toxin protein is adsorbed to soil particles and retains biological activity well beyond expected half-lives, but with no detectable negative effects on soil-dwelling organisms (Saxena and Stotzky 2001).”
Ecological compatibility of GM crops and biological control (2009, neutral): “In addition, genetic transformation of plants can have unintended effects on the plant’s chemical attributes (Saxena and Stotzky, 2001b; Birch et al., 2002; Hjalten et al., 2007), some of which may elicit behavioral responses in natural enemies.”
Bacterial communities associated with the rhizosphere of transgenic Bt 176 maize (Zea mays) and its non transgenic counterpart (2005, background): “However transgenic plants may have unintended modified properties, as is the case of Bt maize where the lignin content is higher than in the non transgenic counterpart (Saxena and Stotzky, 2001).”
