Table II. Identification of proteins associating with ELF3::ELF3-HFC #3 in elf3–2, elf3–2 phyB-9, and elf3–2 elf4–2 compared to GFP-HFC in wild type background. Note that the GFP-HFC identifications are shared with Table I. The unique Normalized Spectral Abundance Factor uses only unique peptides to quantify protein abundance in samples (98). Total unique peptide count refers to all uniquely identified peptides (including those shared with other proteins within the same protein family), while exclusive unique peptide count refers to peptides that are derived from and can be assigned to a single protein. ∫ = uNSAF was multiplied by 100 for comparison. § = Direct interaction that can be assigned from either the literature (see main text for references), or this study (See Fig. 2). † = NOX was identified by only one unique peptide, therefore it was excluded from SAINT analysis.

· = NOX and phyD are included as they each share multiple peptides with another protein in the list (LUX and phyB, respectively).
