NRPD4/NRPE4 interacts with NRPD1 and NRPE1. Coimmunoprecipitation analysis of the interaction between NRPD4 and NRPD1 (A) or NRPE1 (B). Anti-NRPD4 antibody was incubated with protein extracts from flowers of NRPD1-Flag plants, NRPE1-Flag plants, or wild-type plants without transgenes, followed by immunoprecipitation with protein A beads. The bound proteins were washed and eluted, followed by Western blotting with anti-Flag antibody.
