| Popis: | Ethylene-responsive transcription factor (ERF) family genes, which are involved in regulation of metabolic pathways and/or are useful for metabolic engineering, were investigated in the cultured cells of Arabidopsis thaliana. The pectin content in the gelatinous precipitates after the ethanol precipitation of extracts derived from calli of a transgenic cell line, A17, overexpressing an ERF gene (At1g44830), increased in comparison with the control. Expression of genes involved in pectin biosynthesis was up-regulated in the A17 calli. Overexpression of the ERF gene coordinately activates the pectin biosynthetic pathway genes and increases the content of pectin. These results therefore will be useful as a genetic resource for engineering pectin biosynthesis in plants. |
