Genetic organization of contigs 1 and 2 containing the identified genes involved in linuron and DCA catabolism in Variovorax sp. SRS16. Contig 1 contains a 54-kb DNA fragment including dcaQTA₁A₂BR and ccdRCFDE. Upstream of ORF 33, contig 1 includes another 24-kb-long sequenced nucleotide segment. The ORFs of this part of the contig are represented in the corresponding GenBank file JN104632. Contig 2 consists of a 3.5-kb genome fragment containing the linuron hydrolase gene libA (ORF 42). Further information about the different ORFs is shown in Table 1.
