Thinopyrum Bessarabicum Chromosome-Scale Genome Assembly and Annotation

A chromosome-scale reference genome for the diploid halophyte wheat wild relative Thinopyrum bessarabicum, a prioritised donor for salt tolerance breeding. The dataset includes genome assembly, structural and repeat annotation, and functional annotation files totaling 2.4 GB, published by Nicola Walter on figshare in May 2026. This resource resolves evolutionary relationships within the Triticeae tribe and provides a genomic foundation for crop improvement.

Use Cases

• Comparative genomics analysis based on the resolved J genome evolutionary relationships mentioned in the description
• Identifying salt tolerance gene families based on the genome-wide gene content analysis for halophytic capacity
• Characterizing chromosomal introgressions in wheat based on the physically anchored marker framework and dual-reference sequencing pipeline
• Studying chromosomal translocations based on the gene-level resolution of the reciprocal 4/5 translocation across six species

Strengths

• Chromosome-scale assembly provides a high-resolution reference genome for the species
• Includes multiple annotation layers: structural, repeat, and functional annotation
• Dataset size of 2.4 GB indicates substantial genomic data content
• Released under a permissive CC-BY-4.0 license for open reuse

Limitations

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