Annotated Information
Gene Symbol
- Os05g0353400 <=> OsImp β1, Imp β1
Function
- Importin β1 interacts with nuclear transport factors and mediates the import of nuclear proteins.
- OsImpβ1 is specifically required for pollen tube elongation.
Expression
Fig. 2. Expression profiles of the OsImpβ1 gene using GUS assay [1].
- The researchers isolated a pollen-expressed gene, rice Importin β1 (OsImpβ1), from a T-DNA insertional population that was trapped by a promoterless β-glucuronidase (GUS) gene. The GUS reporter was expressed in the anthers and ovaries from early through mature developmental stages. Its expression was also observed in all floral organs. However, these patterns changed as the spikelet developed.
