Contents
Annotated Information
Gene Symbol
- Os03g0123300 <=> TE,TAD1,OsCCS52A,OsWD40-61
Function
- 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.
Phenotypic analysis
- The rice tiller enhancer (te) mutant displays a drastically increased tiller number.
Figure 1. Phenotype characterization of te mutant and map-based cloning of TE.(a) Phenotype of WT and te plants at the seventh leaf stage. (b) Phenotype of WT and te plants at the heading stage. (c) WT produces un-elongated lateral bud (left panel, arrowhead) on the elongated upper internodes, whereas te mutant produces additional tillers (right panel, arrowhead) from the elongated internodes. (d) Tiller number comparison between WT (blue) and te (red) plants at the heading stage. TTs, total tillers; LTs, lower node tillers; HTs, higher node tillers. LTs are the tillers outgrown from the un-elongated basal internodes. HTs are the tillers outgrown from the elongated internodes.[1].
Expression
- 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.
