Pardosa pseudoannulata Spider Cold Acclimation Gene Expression Data

Transcriptional response data from a study on cold adaptation in the wolf spider Pardosa pseudoannulata. The dataset includes differentially expressed genes (DEGs) identified under gradual cold acclimation (4°C vs. 27°C), showing sexual dimorphism with 2,979 DEGs in females and 465 in males. It was authored by Shichang Zhang and last updated on 2026-04-22.

Use Cases

• Identify key cold-tolerance genes like RAC1, JUN, and HSP70 based on the described differential expression analysis.
• Study sexual dimorphism in transcriptional responses to environmental stress based on the reported DEG counts.
• Validate the functional role of the MAPK signaling pathway in arthropod overwintering survival based on the RNAi knockdown results.

Strengths

• Dataset is focused on a specific, understudied agricultural predator (Pardosa pseudoannulata).
• Results are supported by experimental validation via RNAi knockdown, showing a 40-60% reduction in cold-stress survival for key genes.
• Includes a core set of 220 co-expressed genes identified across both sexes.

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 small (121.9 KB), indicating limited scope.
