Document Summary
Lrr component is on the outside of the cell. Figure 24. 8: how br transmission is transmitted, absence of brassinolide. Bin 2 is in a phosphorylated form and is translated to be phosphorylated into bes 1 and bzr1. Transcription factors will be mobilized to cytosol and mediated by the 14- Bl binding activates bri1 and is phosphorylated. Figure 24. 9: form you find in the absence of brassinolide (-bl and ppp, addition of brassinolide (+bl and p; no presence in bl and ppp) Inhibited by auxin and strigolactones: strigolactones affect the proteins that inhibit lateral bus growth, figure 19. 30. Removing apical meristem = lateral bud growth. Re-establish by adding auxin on site of apical meristem removal. Mutations in all 3 maxes = no strigolactones being produced. Max 2: not involved in biosynthetic pathway. Addition of ubiquitin to a particular protein signal it for immediate degradation: ubiquitin is important in proteasome sequence, system exists in all higher eukaryotes.
