Functional and regulatory complexity: challenges and prospects for understanding rice WRKY transcription factors.

Rice WRKY transcription factors exhibit over 100 members with diverse structures and functions, creating significant challenges for precise functional characterization.

• Why it matters: Understanding WRKY TFs is crucial because they regulate key processes in plant growth, development, and stress responses, yet their complexity hampers efforts to link specific genes to traits for crop improvement.
• What they did: The review analyzes the intrinsic properties of WRKY TFs that cause functional ambiguity and proposes a framework combining experimental and computational methods to overcome barriers like redundancy and context-dependent activity.
• The result: Implementing integrated databases and systems-level approaches will enable more accurate functional insights, ultimately supporting strategies to enhance rice stress resilience and productivity.
