Figure 4

A modified sequence directly upstream of the start codon slightly increases transcription efficiency. Transcriptional activation by the promoters CaMV 35S(long) and CaMV 35S(1x) is shown with and without modified ATG context sequence (GCCATGG to a ACCATGG). The expression rates driven without this sequence were defined as 100%. Mean values (MV), standard deviations (SD) and numbers of replication (n) are indicated.
