Distinct MYB activator and repressor complexes in Arabidopsis thaliana
Model based on data by Kobayashi et al (2015). Distinct MYB activator and repressor complexes regulate G2/M gene expression in Arabidopsis proliferating and post-mitotic endocycling cells. MYB3R3/4 may bind directly to MSA elements and E2FB/C to E2F elements. It is not known whether TCX5, the Arabidopsis ortholog of LIN54, binds directly to DNA.
