PIF Protein Motifs Are Highly Conserved across the Plant Kingdom.

Sequence alignment of APB, APA, and MUF1 detected in PIF bHLH proteins. The dashed line indicates intercalated regions. Species abbreviations are in a five letter code, where the first three letters represent the genus and the last two the species (e.g., ORYza SAtiva). For each motif, the respective positions in the protein sequence are indicated. See Supplemental Figure 4 for sequence alignment of MUF2 and 3. See Supplemental Data Set 3 for list of species and Supplemental File 1 for full-length alignment.
