Gene Details:
- Gene ID: Gbar_A07G008330
- Gene Symbol: GbBM
- Gene Name: Beauty Mark
- Genome:
- Species: Gossypium barbadense
Functional Descriptions:
- Demonstrate that GbBM directly targets the promoter of four flavonoid biosynthesis genes to positively regulate petal spot development.
- Introgression of a GbBM allele into G. hirsutum by marker-assisted selection restored petal spot formation, which significantly increased the frequency of honeybee visits in G. hirsutum.
- Beauty Mark (GbBM) gene from G.barbadense, a close allotetraploid relative of G.hirsutum, underlies activation of anthocyanin production, directly leading to formation of a pollinator-attracting purple spot at the base of flower petals.
- Thus, the R2R3-MYB TF protein GbBM functions is specifically expressed in flower petal beauty mark region and functions as a positive transcriptional regulator of flavonoid biosynthesis genes.
