Study Notes
Genetic Purity Testing and ISOzyme Electrophoresis
- Select informative markers from the genome to create a genetic purity panel.
- Informative markers are selected based on their association, location, and chromosome origin.
- Convert selected markers into PCR-based markers for quality testing.
- Validate the panel in silico and on random lines to assess its efficiency.
- Corn snip 16 panel can separate 90% of publicly available wines, while corn 18 panel can separate 95%.
- In the lab, the panel is tested on different inbred lines to ensure it can separate lines and detect hybrids.
- Certain markers, like BDI 1, BDI 3, and BDI 5, are particularly good at detecting hybrids.
- SSOR markers in cucumber can detect hybrids and differentiate between male and female plants.
- Size of PCR products is important for detecting polymorphism and hybrid identification.
- High density panels are needed to determine if two lines are identical.
- One marker difference in the genetic purity panel can indicate a significant difference in the genome.
- Molecular markers are a fast and reliable tool for purity and variety identification, unaffected by the environment.
