Transcriptomic analysis reveals that GA3 enhances reflowering traits and hormone responsiveness in Phalaenopsis.

This research aims to elucidate the mechanism by which exogenous GA3 promotes reflowering in Phalaenopsis ‘Hatuyuki’.
Investigated the effects of different GA3 concentrations (0-200 mg/L) on reflowering traits.
Conducted growth phenotype analysis and transcriptome analysis to identify DEGs and hormone responses.
Performed KEGG enrichment analysis to evaluate signaling pathways involved.
Exogenous GA3 significantly promoted reflowering traits like flower bud differentiation and flowering onset.
Transcriptome analysis revealed 3891 DEGs, with key pathways including plant hormone signal transduction.
Highlighted the role of core endogenous hormones and identified 202 DEGs specific to GA3 response.

Ma et al. (2025) studied this question.
