Gene Details:
- MSU gene ID: LOC_Os01g67980
- RAPdb gene ID: Os01g0907600
- Gene Symbol: REP-1 OsEP3A OsSAG12-1
- Genome: MSU7 , IRGSP-1.0
- Species: Oryza sativa
Functional Descriptions:
- In rice (Oryza sativa), REP-1 is a primary cysteine proteinase responsible for the digestion of seed storage proteins to provide nutrients to support the growth of young seedlings.
- The expression of the gene for REP-1 (Rep1) is induced by gibberellins (GAs) and repressed by abscisic acid (ABA).
- An OsEP3A-specific DNA probe was used to study the effect of various factors on the expression of OsEP3A in germinating seeds and vegetative tissues of rice.
- The expression of OsEP3A is hormonally regulated in germinating seeds, spatially and temporally regulated in vegetative tissues, and nitrogen-regulated in suspension-cultured cells.
- Histochemical studies also indicate that the OsEP3A promoter is sufficient to confer the hormonal regulation of GUS expression in germinating seeds.
- In germinating rice seeds, a cysteine proteinase (REP-1), synthesized in aleurone-layer cells, is a key enzyme in the degradation of the major storage protein, glutelin.
- The OsEP3A promoter is sufficient to confer nitrogen regulation of GUS expression in suspension-cultured cells.
- Down-regulation of OsSAG12-1 results in enhanced senescence and pathogen-induced cell death in transgenic rice plants.
- Expression of OsSAG12-1 is induced during senescence and pathogen-induced cell death.
- Our results suggest that OsSAG12-1 is a negative regulator of cell death in rice.
