A GATA transcription factor OfGATA9 positively regulates flower size of sweet osmanthus.

ABSTRACT:

Background

Flower size significantly influences the visitation of pollinators in angiosperms, and is also a crucial trait that affects commercial value of ornament plants. Sweet osmanthus (Osmanthus fragrans) is an ornamental species characterized by its small and aromatic flowers. GATA transcription factors have been reported to be involved in regulating plant development and growth. However, our understanding of the regulatory functions of GATA transcription factors concerning floral traits in ornamental plants such as sweet osmanthus remains limited.

Results

In this study, we functionally identified a member of the GATA family,, designated as OfGATA9, in sweet osmanthus. The expression of OfGATA9 was found to be transcriptionally up-regulated during the early stages of fl
