From: Risk assessment of genetically engineered plants that can persist and propagate in the environment
Plant | Trait | Findings | References |
---|---|---|---|
Wheat | Resistance against the fungus powdery mildew | In a field experiment two of four GE lines showed up to 56% yield reduction and a 40-fold increase of infection with ergot disease Claviceps purpurea compared with control lines. These effects were not observed in greenhouse experiments | [62] |
Oilseed rape | Herbicide tolerance | Perennial growth | [57] |
Maize | Insecticidal | Changes in proteome (32 differentially expressed proteins mainly involved in carbohydrate and energy metabolism and stress response) | [64] |
Potato | Several experimental traits (antisense invertase and maize ribosome-inactivating proteins) | Altered levels of metabolites (sesquiterpenes and glycoalkaloids) in response to biotic stress | [58] |
Petunia | Colour of flowers | Altered DNA methylation in 35S promoter of the A1 gene | [59] |
Maize | Insecticidal | Bt content higher or lower due to environmental impact factors such as fertilizer, soil quality, pesticide application and climate | [60] |
Maize | Insecticidal | Environmental stress can cause unexpected patterns of expression in the newly introduced DNA | [61] |
Arabidopsis | Herbicide tolerance | Drought and heat stress caused increased seed germination ratios | [30] |
Cotton | Insecticidal | Bt content is influenced by environmental conditions and genetic backgrounds |
