The paper identifies the candidate gene SUGI_0493010 for MS2-type male sterility in Japanese cedar using linkage mapping and transcriptomic data.

This paper develops a simple, environmentally friendly DNA extraction and PCR-RFLP method for genotyping the MS4 gene in Cryptomeria japonica, suitable for field use.

The paper assesses mutational effects of gamma radiation on Arabidopsis thaliana, finding increased de novo mutations with radiation dose and higher mutagenic effects during the reproductive stage.

The paper identifies a male-sterile gene (MS1) in Japanese cedar by analyzing deletions in a lipid transfer protein gene and proposes marker-assisted selection for breeding.

The paper develops PCR and LAMP markers to detect mutant alleles of the MS1 gene in Cryptomeria japonica for pollen-free cultivar production.

This study identifies markers for the male-sterility gene MS1 in Cryptomeria japonica and demonstrates their use in marker-assisted selection across different populations.
