| − | ''Tillering and Dwarf 1''(''TAD1''), which encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. The protein interacts with moC1, forms a complex with osAPC10 and functions as a co-activator of APC/C to target MoC1 for degradation in a cell-cycle-dependent manner. | + | * '''''TE''''' encodes a rice homologue of Cdh1, and that TE acts as an activator of the anaphase promoting complex/cyclosome (APC/C) complex |
| | + | * Besides having a conserved role in regulating cell cycle, APC/C TE has a unique function in regulating the plant-specific postembryonic shoot branching and tillering, which are major determinants of plant architecture and grain yield. |
| | | | |
| − | ''TAD1'' encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.During the cell-cycl progression, ''TAD1'' shows an oscillating expression pattern with a higher level in the G1-phase.The ''TAD1''-deduced amino-acid sequence contains several conserved domains, including seven WD repeats, C-box, CSM, RVL and IR motifs.

| − | Sequence analysis revealed that MOC1 harbours a typical D-box at the N-terminal (Fig. 4a). Therefore, it is very likely that MOC1 and TAD1 directly interact to control rice tillering. MOC1–GFP fusion protein could capture the TAD1–FLAG fusion protein, suggesting an in vivo interaction between MOC1 and TAD1 (Fig. 4b). Bimolecular fluorescence complementation shown in Fig. 4c, when the full-length cDNAs of TAD1 and MOC1 were introduced into rice protoplasts simultaneously, the fluorescence signal was detected in the nucleus, indicating that TAD1 can directly interact with MOC1 in the nucleus. Furthermore, when two conserved residues, arginine and leucine, of the D-box at the N-terminal were changed into alanine (Fig. 4a), the MOC1 protein was unable to interact with TAD1, demonstrating that the D-box is indispensable for the interaction between MOC1 and TAD1 (Fig. 4c). In addition, a series of truncated TAD1 proteins were generated to determine the domains that are essential for the interaction with MOC1 viathe BiFC analysis (Fig. 4d). The results showed that the N-terminal 203 amino acids of TAD1 are sufficient to interact with MOC1.

| | + | * TE coexpresses with MOC1 in the axil of leaves, where the APC/C TE complex mediates the degradation of MOC1 by the ubiquitin–26S proteasome pathway, and consequently downregulates the expression of the meristem identity gene Oryza sativa homeobox 1, thus repressing axillary meristem initiation and formation. |

| − | ''TAD1'' has an oscillated expression pattern during the cell-cycle progression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. The overexpression of MOC1 resulted in similar phenotypes to that of the tad1mutant plant, such as more tillers and reduced plant height, whereas TAD1-overexpressing transgenic plants showed a reduced tiller number,a similar phenotype to ''moc1''.
