Outline of Final Research Achievements

The causative gene of a male-sterile Japanese cedar ‘Sosyun’ was investigated to develop a molecular marker for identifying male-sterile trees. The result of transcriptome analysis suggested that the causative gene of Sosyun has expressed at the meiosis stage or at the former stages. From the RNA sequencing data, the linkage analysis and QTL analysis, several SNP (Single Nucleotide Polymorphism)s tightly linked with the male-sterile trait were selected. We developed the SNP markers using these selected SNPs and applied them to the progeny of Sosyun. One SNP marker was able to detect not only the male-sterile individuals but also the heterozygous ones.
