Poplar WRKY Gene Family Analysis for Botryosphaeria dothidea Resistance

102 WRKY transcription factors were identified in Populus trichocarpa through BLASTp and Hidden Markov Model screening. The study, authored by Dongchen Shen and last updated in March 2026, systematically elucidates the evolutionary characteristics of this gene family and validates the role of PdpapWRKY11 in enhancing fungal resistance via lignin accumulation. This research provides foundational insights into transcription factor functions in poplar disease resistance.

Use Cases

• Study the evolution and classification of WRKY transcription factor families based on phylogenetic analysis.
• Investigate the role of specific genes like PdpapWRKY11 in enhancing pathogen resistance through molecular validation.
• Analyze the relationship between transcription factor regulation and lignin biosynthesis pathways in plant defense.
• Model gene family functional diversification driven by motif combinations and duplication events.

Strengths

• Includes genome-wide identification of 102 specific WRKY transcription factors.
• Provides molecular functional validation for a key gene, PdpapWRKY11, in a transgenic poplar system.
• Integrates multiple analysis methods: BLASTp, HMM screening, RNA-seq, and phylogenetic classification.

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 a 198.5 KB DOC file, indicating a very limited data scope, likely focused on textual results and analysis.
