Pepper JAZ Gene Family Pan-Genome Analysis Across 20 Accessions

A pan-genome analysis of the JAZ gene family across 20 diverse pepper (Capsicum annuum L.) accessions, conducted by Huaming Zhong and last updated in April 2026. The dataset details 12 identified CaJAZ members, their evolutionary patterns, structural variations, and transcriptional responses to hormones like MeJA, ABA, and SA. It is provided as a 20.9 KB Excel file under a CC-BY-4.0 license.

Use Cases

• Identify core versus variable JAZ gene haplotypes based on the described pan-genome architecture for breeding applications.
• Analyze promoter motifs like Box 4/G-box and ABRE for regulatory element studies.
• Study structural variations (PAV/CNV/motif anomalies) such as the CaJAZ6 P-Y anchor truncation to understand functional divergence.
• Model temporal transcriptional modules based on hormone response patterns (MeJA, ABA, SA) described in the study.
• Investigate gene duplication events, like the tandem duplication of CaJAZ9, in relation to lineage-specific adaptation.

Strengths

• Analysis covers 20 diverse pepper accessions, providing a comparative genomic perspective.
• Identifies 12 specific CaJAZ gene members with detailed functional and evolutionary characterization.
• Includes promoter analysis revealing specific regulatory elements (e.g., Box 4, ABRE, CGTCA).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (20.9 KB), indicating limited raw data scope.
