Carotenoid genes
Genomic DNA of P . ananatis PA13, a bacterial pathogen of rice, was used as the template to amplify carotenoid biosynthetic genes. The carotenoid genes are located on a plasmid (PAGR_p; CP003086). Figure 1 shows the carotenoid gene clusters of P . ananatisPA13 and P . agglomerans Eho10 (M87280; Hundle et al ., 1994).
