Gene Details:

• Gene ID: Peaxi162Scf00285g00011
• Gene Symbol: PhOBF1
• Gene Name:
• Genome: Sol Genomics Network (https://solgenomics.net/organism/Petunia_axillaris/genome)
• Species: Petunia hybrida

Functional Descriptions:

• A petunia transcription factor, PhOBF1, regulates flower senescence by modulating gibberellin biosynthesis.
• Silencing and overexpression of PhOBF1 affected expression levels of a few genes involved in the GA biosynthesis and signaling pathways, as well as accumulation levels of bioactive GAs GA1 and GA3.
• PhOBF1 was observed to specifically bind to the PhGA20ox3 promoter containing a G-box motif. Transient silencing of PhGA20ox3 in petunia plants through tobacco rattle virus-based virus-induced gene silencing method led to accelerated corolla senescence.
• PhOBF1 functions as a negative regulator of ethylene-mediated flower senescence by modulating the GA production.
• PhOBF1, a petunia ocs element binding factor, plays an important role in antiviral RNA silencing.
