Comparison of the insect resistance conferred by different multigene vector structures and transgenic lines.
| The carrier | S16 | S17 | N25 |
|---|---|---|---|
| Receptor species | Populus euramericana 107 | Populus euramericana 107 | European Populus nigra L |
| Number of foreign genes | 3 | 3 | 4 |
| Promoter | yes | yes | yes |
| Enhancer | not | not | AtADH 5′-UTR |
| MAR | not | not | yes |
| Close to the NptII gene | Cry1Ac | Cry1Ac | Cry3A |
| Mortality of 1-age Lepidoptera larvae | 42.2%∼66.7% | 0.0%∼68.89% | 77%–97% |
| Mortality of 1-year-old Coleoptera larvae | 100% | 100% | 100% |
S16, S17, and N25 represent the carrier structures of Yang et al. (2016); Liu et al. (2016) and this experiment. The comparison data are from the above two references and the statistical data of this experiment.
