| Outline of Final Research Achievements |
Genes responsible for dioecy, self-incompatibility, and apomixis, which have been related to diversification of plant reproduction systems, are located on chromosomal non-recombining regions. Thus, it has been difficult to identify these genes. In this study, mutant lines having deletions on the non-recombining regions were developed. The deletion maps of the lines were calculated by using the newly developed software “DelMapper”, and used for narrowing down the positions of the responsible genes. Together with the information for genomes and transcriptomes obtained from next-generation sequencing, candidates for the responsible genes were successfully listed.
