Expression

Organism Comment Expression
Arabidopsis thaliana in unwounded plants, exogenously applied methyl jasmonate activates the FAD7 promoter in roots, whereas it represses FAD7 promoter activity in leaves down
Arabidopsis thaliana activation of the FAD7 promoter by local wounding treatments. Wounding induces the expression of the FAD7 gene in rosette leaves (2fold), stems (29fold), and roots(10fold). Significant induction by wounding is observed in the overall tissues of stems and includes trichomes, the epidermis, cortex, vascular system, and the pith of the parenchyma. Strong promoter activity is found preferentially in the vascular tissues of wounded roots. Wound activation of the FAD7 promoter in roots occurs via the octadecanoid pathway, inhibitors salicylic acid and n-propyl gallate strongly suppress the wound activation of the FAD7 promoter in roots but not in leaves or stems. Light attenuates the wound-inducing activity of the FAD7 promoter in roots, although in unwounded roots, illumination does not affect the expression of the FAD7 gene. In unwounded plants, exogenously applied methyl jasmonate activates the FAD7 promoter in roots, whereas it represses FAD7 promoter activity in leaves up
