Positional identification of a candidate gene for MALE STERILITY 2 (MS2) by linkage mapping and transcriptomic data in Cryptomeria japonica D. Don

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

Transcriptome differentiation in Cryptomeria japonica trees with different origins growing in the north and south of Japan

The paper identifies gene modules associated with local adaptation in Cryptomeria japonica trees from different geographic origins in Japan.

Whole chloroplast genomes reveal a complex genetic legacy of lost lineages, past radiations and secondary contacts in the dominant temperate deciduous tree genus Fagus

The paper uses whole chloroplast genomes to trace the genetic history of Fagus, revealing ancient lineages, past radiations, and genetic admixture events.

A chromosome-level genome assembly of amodel conifer plant, the Japanese cedar,Cryptomeria japonica D. Don

The paper presents a chromosome-level genome assembly for the Japanese cedar, using long-read and Hi-C sequencing to achieve high contiguity and accuracy.

A DNA barcode database for the woody plants of Japan

The paper develops a DNA barcode database for Japanese woody plants, covering 834 species and showing high identification rates using chloroplast DNA regions.

Identification and genetic diversity analysis of a male-sterile gene (MS1) in Japanese cedar (Cryptomeria japonica D. Don)

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.

Development of diagnostic PCR and LAMP markers for MALE STERILITY 1 (MS1) in Cryptomeria japonica D. Don

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