Dark and light regulated chlorophyll A/B binding protein promoter- regulatory system

摘要

A plant chlorophyll a/b binding (Cab) protein gene was isolated from a maize genomic library. The promoter/regulatory system of this gene actively functions in controlling Cab gene expression under conditions of darkness and in enhancing gene expression under conditions of light. This invention contemplates the utilization of the Cab promoter/regulatory system in regulating non-homologous structural gene expression in transgenic plants under conditions of darkness followed by further enhancement of gene expression under conditions of light.
