Substitution of redox chemicals for radiation in phytochrome-mediated photomorphogenesis.

abstract：:The cereal aleurone layer is a model system for studying the regulation of transcription by gibberellin (GA) and abscisic acid (ABA). GA stimulates and ABA prevents the transcription of genes for alpha-amylases and other secreted hydrolytic enzymes, but how GA and ABA affect the transcription of other genes is largely...
