Figure 3.
A simplified model of SCE development showing transcription factors (diamonds) and enzymes or other proteins (rectangles) involved in cell wall production. Slashes denote functionally redundant homologs, and colors highlight proteins with similar functions. Overlapping shapes form a protein complex. In addition, KNAT7 can directly interact with MYB5. Thin arrows indicate direct transcriptional activation, while dashes show putative interactions that have not been validated in SCE cells.
