Dioscorea Tokoro Genes in X- and Y-Specific Chromosome Regions

A list of genes located in the X-specific region of the dioecious monocot Dioscorea tokoro, a wild yam endemic to East Asia. The dataset, 13.5 KB in size, was published by Aoi Kudoh on figshare under a CC-BY-4.0 license and last updated in April 2026. It supports research on the molecular basis of sex determination in plants with XY systems.

Use Cases

• Identifying candidate sex-determination genes based on location within Y-specific regions.
• Comparative genomics of sex chromosomes in dioecious plants based on X- and Y-specific sequences.
• Studying the evolution of dioecy in monocots based on gene content in sex-determination regions.
• Functional analysis of BLH9 and HSP90 homologs in plant development based on their proposed roles.

Strengths

• Dataset is small (13.5 KB), facilitating quick download and inspection.
• Derived from chromosome-scale and haplotype-resolved genome assemblies, as mentioned in the source study.
• Focuses on a specific, biologically defined region (X-specific region on chromosome 3).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
