TIL Gene Family Analysis in Five Brassicaceae Species and BrTIL1 Cold Tolerance Study

23 Temperature-Induced Lipocalin (TIL) genes identified across five Brassicaceae species, including Arabidopsis thaliana and four Brassica species. The dataset, authored by Zhengnan Xu and last updated in March 2026, provides a systematic analysis of gene structures, evolutionary relationships, and cis-acting elements. Functional validation shows the Brassica rapa TIL1 gene positively regulates cold tolerance, with overexpression linked to higher survival rates and antioxidant enzyme activities.

Use Cases

• Comparative genomics analysis based on identified TIL gene structures and evolutionary relationships.
• Studying cold stress response mechanisms based on BrTIL1 expression and functional validation data.
• Identifying potential gene interaction networks based on the six BrTIL1-interacting proteins found via yeast two-hybrid screening.
• Analyzing promoter regions for stress-responsive elements based on the cis-acting element data mentioned.

Strengths

• Includes data for 23 identified TIL genes across five species.
• Functional validation includes specific metrics like survival rates and levels of three antioxidant enzymes (POD, CAT, SOD).
• Provides protein-protein interaction data from a yeast two-hybrid screen identifying six interactors.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 10.6 KB, indicating limited scope.
