Figure 3From: A 28 nt long synthetic 5′UTR (synJ) as an enhancer of transgene expression in dicotyledonous plantsGUS activity observed in cotton callus transformed with the constructs 35S(synJ), 35S(Ω) and 35S(AMV). Each bar represents the mean GUS activity of the two experimental replicates measured with one independent callus. N denotes the number of callus analyzed in each case. The line represents the GUS activity of 1500 pmolMU/min/μg protein.Back to article page
