Voorbeeldzinnen

1. Restriction fragment length polymorphism (RFLP) analysis (Cook et al., 1989).
2. The restriction fragments obtained from R. solanacearum-specific fragment are 457 bp and 96 bp in size.
3. PCR products amplified from R. solanacearum DNA produce a distinctive restriction fragment length polymorphism with enzyme Taq I after incubation at 65 °C for 30 minutes.
4. PCR products amplified from R. solanacearum DNA produce a distinctive restriction fragment length polymorphism with enzyme Ava II after incubation at 37 °C.
5. PCR products amplified from R. solanacearum DNA produce a distinctive restriction fragment length polymorphism with enzyme Taq I after incubation at 65 °C for 30 minutes. The restriction fragments obtained from R. solanacearum-specific fragment are 457 bp and 96 bp in size.
6. Resolve the digested fragments by agarose gel electrophoresis as before and observe characteristic restriction fragment pattern under UV transillumination after ethidium bromide staining and compare with the undigested and digested positive control.
7. A positive identification of R. solanacearum is achieved if the PCR amplicons are the same size and have the same restriction fragment length polymorphisms as for the positive control strain.
8. A positive identification of C. m. subsp.sepedonicus is achieved if the PCR amplicons are the same size and have the same restriction fragment length polymorphisms as for the positive control strain.
9. PCR products amplified from R. solanacearum DNA produce a distinctive restriction fragment length polymorphism with enzyme Bsm I or an Isoschizomere (e.g. Mva 1269 I) after incubation at 65 °C for 30 minutes.
10. PCR products amplified from R. solanacearum DNA using primers Rs-1-F and Rs-1-R produce a distinctive restriction fragment length polymorphism with enzyme Bsm I or an Isoschizomere (e.g. Mva 1269 I) after incubation at 65 °C for 30 minutes. PCR products amplified from R. solanacearum DNA using primers Rs-1-F and Rs-3-R have no restriction sites.
11. The MluI restriction fragment, which contains the two cassettes specified in points (a) and (b) of the first subparagraph, does not contain the neomycin phosphotransferase type II gene conferring resistance to certain aminoglycoside antibiotics or the origin of replication from Escherichia coli, although both sequences are present in the original plasmid PV-ZMGT32L.
12. PCR products amplified from R. solanacearum DNA produce a distinctive restriction fragment length polymorphism with enzyme Bsm I or an Isoschizomere (e.g. Mva 1269 I) after incubation at 65 °C for 30 minutes. 4. R. solanacearum biovar-specific PCR protocol (Pastrik et al., 2001) 4.1. Oligonucleotide primers
13. PCR products amplified from R. solanacearum DNA using primers Rs-1-F and Rs-1-R produce a distinctive restriction fragment length polymorphism with enzyme Bsm I or an Isoschizomere (e.g. Mva 1269 I) after incubation at 65 °C for 30 minutes.
14. The genetically modified organisms to be placed on the market as or in products, hereinafter ‘the product’, are grains of maize (Zea mays L.), with resistance to the corn rootworm (Diabrotica spp.), derived from the Zea mays cell culture line AT824 (initiated from immature embryos of an inbred maize line AT), which has been transformed using particle acceleration technology with a MluI DNA restriction fragment isolated from plasmid PV-ZMIR13.
15. The genetically modified organisms to be placed on the market as or in products, hereinafter ‘the product’, are grains of maize (Zea mays L.), with increased tolerance to the herbicide glyphosate, derived from the maize line NK603 transformation event, which has been transformed using particle acceleration technology with a MluI restriction fragment isolated from plasmid PV-ZMGT32L and which contains the following DNA sequences in two intact cassettes:
