The longevity of transcripts of MU15 and MU7 (2) reporter genes. Each contains a GUS coding sequence and a psaB 3′ terminus. MU15 contains rbcL sequences extending to +350 and MU7 rbcL to +97. Cells were grown on cycles of 12 h light/12 h darkness. D (dark) samples were taken just before illumination and L (light) samples were taken 1 h later. RNA was estimated by slot blotting using a GUS coding sequence probe. Representative blots are shown at right. The light/dark ratios (the fraction of GUS transcripts present in cells after 1 h of illumination compared with the amount of transcript present just before illumination) are calculated from values obtained by densitometry and shown at left.
