LITERATURE
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
at 4°C, the transcript level of CsFAD7 decreases significantly 1 h after the stress and then recovers. After 6 h, the expression level is of CsFAD7 remains at levels below the control (0 h) until 48 h, at -5°C, CsFAD7 decreases significantly and then remains stable until 48 h
at 4°C, the transcript level of CsFAD8 decreases significantly 1 h after the stress and then recovers. After 6 h, the expression level of FAD8 is higher than the control at 24 h, at -5°C, CsFAD8 expression decreases significantly and then remains stable until 48 h
FAD7 is up-regulated by wounding but not by low temperature. Total fatty acid and linolenic acid content are higher both, in wounded and intact leaves of plants exposed to low temperature
FAD8 is up-regulated by cold stress but not by wounding. Total fatty acid and linolenic acid content are higher both, in wounded and intact leaves of plants exposed to low temperature
gene fad7 is rapidly induced in elicitor-treated cell culture leading to an accumulation of mRNA in leaves and as well in fungal infection sites in leaf buds, pathogen invasion induces the enzyme
-
glycine betaine induces the enzyme expression in tomato plants at low temperature
high-salt treatment induces the accumulation of the ZmFAD7 transcript in roots but drought and abscisic acid have no effect on its expression. Cycloheximide induces the accumulation of the ZmFAD7 transcript in roots
high-salt treatment induces the accumulation of the ZmFAD8 transcript in roots but drought and abscisic acid have no effect on its expression
in unwounded plants, exogenously applied methyl jasmonate activates the FAD7 promoter in roots, whereas it represses FAD7 promoter activity in leaves
in wild-type plants cold-acclimated at 4°C, the transcript levels of OsFAD8 increase significantly, and the expression levels increase in comparison to those of wild-type and of genes OsFAD7 and OsFAD3. OsFAD8 is a cold-inducible gene
