FIG. 1.
Genetic organization of the A. caviae Sch3N (A), A. hydrophila AH-3 (B), and A. hydrophila ATCC 7966T (C) flm loci. Predicted ORFs were named after their homologues in other bacterial species and are indicated by open arrows, which indicate the direction of transcription. The same pattern in arrows indicates orthologous genes in the clusters. The ORF labeled “hypo” is a gene encoding a hypothetical protein. ORFs of interest in A. hydrophila ATCC 7966T are indicated by their gene locus numbers. Open triangles indicate the sites of insertion of the antibiotic resistance cassette, and the corresponding mutant designations are indicated above the triangles. The thin arrows indicate transcriptional units as determined by RT-PCR.
