Gene Details:

• Gene ID: Dca5929
• Gene Symbol: DcWRKY75
• Gene Name: WRKY transcription factor75
• Genome: Carnation Genome database (http://carnation.kazusa.or.jp)
• Species: Dianthus caryophyllus

Functional Descriptions:

• The transcription factors DcHB30 and DcWRKY75 antagonistically regulate ethylene-induced petal senescence in carnation.
• We found that silencing DcHB30 accelerated ethylene-induced petal senescence and that DcHB30 physically interacts with DcWRKY75, a positive regulator of ethylene-induced petal senescence.
• Phenotypic characterization and molecular evidence indicated that DcHB30 and DcWRKY75 competitively regulate the expression of their co-targeted genes DcACS1, DcACO1, DcSAG12, and DcSAG29 by reciprocally inhibiting the DNA-binding activity of each other on the gene promoters.
• We demonstrate that DcHB30 delays petal senescence by interacting with DcWRKY75 and inhibiting its DNA-binding activity on the promoters of co-targeted genes. This mechanism provides a potential new strategy for fine-tuning the postharvest preservation of cut carnation flowers.
