Fig. 8From: Biodegradation of isoproturon by Escherichia coli expressing a Pseudomonas putida catechol 1,2-dioxygenase geneThe expression levels of catA gene. The qRT-PCR analysis results measure the relative mRNA levels of catA gene of P. putida and expressed E. coli. Bars represent mean values ± standard error. **** mean significant fold change.
