Fig. 2.

Response of the P. fluorescens Pf0-1 alginate biosynthetic locus to dehydration stress. Dark grey arrows show alginate genes annotated with locus tags and alg gene names. Genomic coordinates in the Pf0-1 genome are shown above the genes. Below each gene is the transcriptional response to dehydration expressed as fold increase in RPKM (reads per kilobase of transcript, per million mapped reads) relative to controls. Bold numbers indicate significant changes in expression. Bars under alg44 and algD indicate regions that were deleted when constructing mutants.
