Gene Details:

• Gene ID: Potri.018G029500
• Gene Symbol: PtoHY5a
• Gene Name: ELONGATED HYPOCOTYL 5a
• 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.
• PtoHY5a, an orthologs of the photomorphogenesis regulatory factor ELONGATED HYPOCOTYL 5 (HY5) in poplar (Populus tomentosa), that directly activates PtoFT2 expression and represses the circadian oscillation of LHY2, indirectly activating PtoFT2 expression.
• PtoHY5a affects vegetative growth and rescues the early flowering phenotype of the Arabidopsis hy5 mutant.
• PtoHY5a suppresses SD-induced growth cessation, bud set, and chilling-induced bud burst.
• 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.
