Expression

Organism Comment Expression
Petunia x hybrida PhBPBT is regulated by both light and an endogenous circadian rhythm, while it is also differentially regulated in response to ethylene in a tissue-specific manner. 24 hours following pollination of flowers, expression of PhBPBT decreases in the corolla, while it increases in the ovary after 48 h. This is caused by ethylene that is emitted from the flower coinciding with fertilization as this is not observed in transgenic ethylene-insensitive plants (CaMV35S::etr1-1, 44568). Ethylene is also emitted from vegetative tissue of petunia following mechanical wounding, resulting in an increase in PhBPBT expression in the leaves where expression is normally below detection levels down

General Information

General Information Comment Organism
physiological function it is hypothesized that PhBPBT and subsequent benzyl benzoate production is involved in defencerelated processes in the corolla prior to pollination in the ovary immediately following fertilization, and in vegetative tissue in response to wounding Petunia x hybrida
