| Outline of Final Research Achievements |
The objective of this study is to develop efficient methods for generation of plant artificial chromosomes that are able to accept a number of genes. The newly designed T-DNA construct (pDLHC) contained two LoxPs, one of which is transposable by a transposase. This transposition was designed to induce expression of the Cre recombinase gene, resulting in site-specific recombination between two separated LoxPs. Among the progeny of rice plants transformed with pDLHC, one transformant was found to contain a large deletion on chromosome 10, which was caused by elimination of a DNA molecule circled by recombination between two LoxPs. If the centromere functions would be given to the circular DNA, artificial ring chromosomes would be generated.
