Figure 4From: A 28 nt long synthetic 5′UTR (synJ) as an enhancer of transgene expression in dicotyledonous plantsComparative analysis of nos(nos), nos(synJ) and nos(RT) constructs. GUS activity in transformed cotton callus containing the expression constructs nos(nos), nos(synJ) and nos(RT) as observed in two independent experiments. Each circle represents GUS activity measured in one independent callus.Back to article page
