| pubmed-article:10987138 | pubmed:abstractText | The green fluorescent protein (GFP) from the jellyfish Aequorea victoria is a widely used reporter that can be directly visualized in the living cells in both animals and plants. We inserted a synthetic gene (sgfp) encoding a modified form of the GFP into expression vector, Act1-sgfp for the direct expression of GFP which is easily detectable in rice plants. Green fluorescence emitted from GFP could be visualized in calli, dry seeds, roots and seedlings with green shoots of transgenic rice plants. In our visualization system with a charge-coupled device camera, band-pass filters and a light source, the presence of red chlorophyll autofluorescence from chloroplasts did not alter the green fluorescence of GFP. These results demonstrate that GFP could be used as a non-destructive visual selection marker for examining gene expression in transformed calli, dry seeds and young plants. | lld:pubmed |
