Gene Details:
- Gene ID: Potri.010G179700
- Gene Symbol: PtoFT2
- Gene Name: FLOWERING LOCUS T2
- Genome:
- Species: Populus tomentosa
Functional Descriptions:
- ELONGATED HYPOCOTYL 5a (PtoHY5a) modulates FLOWERING LOCUS T2 (PtoHY5a) and gibberellin levels to control dormancy and bud break in poplar.
- As PtoFT2 can be regulated by PtoHY5a in poplar, it is necessary to understand whether PtoHY5a is involved in the seasonal growth of trees.
- PtoFT2 displayed a diurnal expression pattern in the WT plants, with the highest expression at Zeitgeber time 12h (ZT12) under LDs, however, the peak expression of PtoFT2 appeared 8 h earlier in PtoHY5a-OE plants, and was delayed by 4h in PtoHY5a-KO plants under LDs.
- PtoHY5a modulates seasonal growth in poplar by regulating the PtoPHYB2–PtoHY5a–PtoFT2 module to determine the onset of winter dormancy, and by fine-tuning GA levels to control bud-break.
- Overexpression of PtoFT2 suppresses the premature growth cessation and early bud set phenotype of PtoHY5a-KO plants.
