Jimai 22 Wheat Genome Assembly for Freezing Tolerance Analysis

A high-quality genome assembly for the elite wheat cultivar Jimai 22 (JM22) was generated using PacBio HiFi and chromosome conformation capture sequencing. The assembly is 197.5 MB in size and was published by Guangwei Li on figshare in May 2026. It provides a resource for delineating the genetic basis of freezing tolerance, specifically highlighting CBF2 gene haplotypes.

Use Cases

• Comparative genomics analysis based on the high-quality JM22 genome assembly
• Identifying genetic markers for freezing tolerance based on the described CBF2 gene haplotypes
• Serving as a reference genome for breeding studies based on JM22's status as a foundation parent for over 200 varieties

Strengths

• 197.5 MB high-quality genome assembly generated with PacBio HiFi sequencing
• Described as more contiguous and accurate than a prior JM22 assembly published in Nature in 2025
• CC-BY-4.0 license allows for broad reuse and sharing

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for certain analyses
