Chilling reversal: How phyB–PIF4 rewiring fine‐tunes seasonal growth in cold‐adapted aspen

Year: 2025

Type: article

Abstract: In poplar trees, a molecular switch involving phytochrome B and PHYTOCHROME-INTERACTING FACTOR 4 responds to cool temperatures by keeping growth active, preventing premature dormancy. This mechanism, which differs from that in Arabidopsis, helps trees adapt to cool summers and ensures survival in seasonal environments.
