Annotated Information
Gene Symbol
- Os07g0207700 <=> sh-h, OsCPL1
Function
- sh-h encodes a protein containing a conserved carboxy-terminal domain (CTD) phosphatase domain, was named Oryza sativa CTD phosphataselike 1 (OsCPL1).
- OsCPL1 represses differentiation of the abscission layer during panicle development.
Mutation
Figure 1. Shattering degree and anatomy of the abscission layer region. [1].
- Compared with the wild-type Hwacheong line, the shattering mutant line, Hsh, has a well-developed abscission layer and a drastically reduced grain pedicel BTS (Figure 1a,b).
- RNA interference (RNAi) transgenic lines with suppressed expression of sh-h exhibited greater seed shattering.
Expression
- The expression of sh-h was detected in the leaves and roots at all growth stages, and in young panicles of various lengths from both wild and mutant lines
Evolution
Sublocalization
- Subcellular localization and biochemical analysis revealed that the OsCPL1 protein is a nuclear phosphatase, a common characteristic of metazoan CTD phosphatases involved in cell differentiation.
