FT/TFL1 gene family members show functional divergence despite conserved PEBP structural features, with FT promoting and TFL1 delaying or repressing flowering across plant lineages.
- Why it matters: The classical “FT activator/TFL1 repressor” paradigm may not explain expanded gene-family behaviors across species, tissues, and environmental conditions.
- What they did: This review synthesizes comparative genomics on FT/TFL1 copy-number variation and expansion, summarizes mechanisms of functional diversification, and integrates evidence on protein interaction rewiring and environmental signal integration.
- The result: It provides a unified framework for how evolutionary and environmental factors shape FT/TFL1, guiding future studies on reproductive development, adaptive evolution, and applied flowering-trait manipulation.
