HD2C Interacts with HD2B and Forms Homo-Oligomer.

(A) List of partial proteins copurified with HD2C-FLAG. “Unique peptides” indicates the number of identified peptides that are mapped to only one protein. “Coverage” indicates the percentage of the protein covered by unique peptides identified in this experiment.

(B) Co-IP of HD2C and HD2B using Arabidopsis F1 plants expressing both HD2C-HA and HD2B-FLAG.

(C) Co-IP of HD2C-FLAG and HD2C-HA in N. benthamiana.

(D) Co-IP of HD2B-FLAG and HD2B-HA in N. benthamiana.

(E) Co-IP between GFP tagged HD2C mutants and wild-type HD2B-FLAG in N. benthamiana.

(F) Co-IP between GFP tagged HD2C mutants and wild-type HD2C-FLAG in N. benthamiana.
