Project Title
- Separation and characterization of proteins from green and etiolated shoots of rice (Oryza sativa L.):Towards a rice proteome
The Background of This Project
Plant Culture & Treatment
- Green and etiolated shoots of rice (Oryza sativa L. cultivar Nipponbare) were used for this study. Rice seeds were sown on vermiculite and incubated at 25oC under light for 12 h and in the dark for 12 h (for green shoots) or in the dark for 24 h (for etiolated shoots)
Protein Extraction and 2-D PAGE
- Following separation by 2-D PAGE, the proteins were electroblotted onto a polyvinylidene difluoride (PVDF)membrane (ProBlott; Applied Biosystems, Foster City,CA, USA) and detected by Ponceau 3R staining [11]. The spots were excised from the PVDF membrane and applied to the upper glass block of the reaction chamber in a gas-phase protein sequencer (477A; Applied Biosystems). Edman degradation was performed according to the standard program supplied by Applied Biosystems.The released phenylthiohydantoin amino acid derivatives were identified by the on-line systems of high performance liquid chromatography (120A; Applied Biosystems).
