Plant minichromosomes

- Epigenetic centromere function precludes build-up method for plant minichromosomes.
- Transgene stacking method has been demonstrated for continued addition to target site.
- B chromosomes can be transferred from haploid inducer lines to target genotypes.
- Minichromosomes have the potential to stack many genes.
- Minichromosomes have potential as a massive scale editing tool.
