Characterization of phytochrome-regulated gene expression in a photoautotrophic cell suspension: possible role for calmodulin.


A photoautotrophic suspension culture of soybeans was found to exhibit light-dependent expression of the genes encoding the major chlorophyll a- and b-binding protein (CAB). The expression was mediated by phytochrome, since it was induced by red light and reversed by far-red light. The maximal level as well as the kinetics of the induction were comparable… (More)
