Reverse Chromatin Immunoprecipitation (R-ChIP) enables investigation of the upstream regulators of plant genes

Abstract

Xuejing Wen et al. present a new method, Reverse Chromatin Immunoprecipitation (R-ChIP), for analyzing DNA-protein interactions specifically in plant cells. They apply R-ChIP to identify proteins binding to the promoter of the Arabidopsis gene AtCAT3 and optimize the method using transient transformation of the target promoter to increase efficiency.
