Poplar WRKY Gene Family Analysis for Botryosphaeria Dothidea Resistance

102 WRKY transcription factors were identified in Populus trichocarpa through genome-wide screening. This research paper details the functional validation of PdpapWRKY11, which enhances canker resistance by upregulating lignin biosynthesis genes. The study, authored by Dongchen Shen and last updated in March 2026, provides foundational insights for improving poplar disease resistance.

Use Cases

• Study the evolution and classification of WRKY transcription factor families based on phylogenetic analysis.
• Investigate gene duplication events and cis-regulatory elements driving functional diversification in poplar.
• Model the activation of phenylpropanoid pathway genes (PAL, CAD) for lignin accumulation in disease resistance.
• Validate candidate genes like WRKY11 for enhancing pathogen resistance in transgenic plant lines.

Strengths

• Identifies 102 WRKY transcription factors in Populus trichocarpa.
• Includes molecular functional validation of a specific gene (PdpapWRKY11).
• Released under a permissive CC-BY-4.0 license.

Limitations

• Data is presented as a 3.8 MB PDF; underlying raw data or column definitions are unavailable.
• Row count and data structure are unknown, limiting suitability assessment.
• The description focuses on methodology and results; specific dataset features for direct analysis are not detailed.
