| Outline of Final Research Achievements |
Having efficient chloroplast genome transformation and genetic screening system established in Marcantia, measurement of genome translocation rate from chloroplast genome to the nucleus has been done. Analysis of measurement of genome translocation rate revealed that the translocation rate is quite low in Marchantia. Because Marchantia suppresses the translocation, genetic screening using T-DNA insertion lines has been done to find a mutant in which the translocation occurs. As a result, one mutant has been isolated and another allele for the gene was prepared by gene targeting. Now, I am not able to conclude because NGS analysis have not detected any novel chloroplast genome insertion in the nucleus in mutants generated by gene targeting. I am still analyzing while improving method.
