Fig. 1From: Genomewide transcriptional response of Escherichia coli O157:H7 to norepinephrineGraphical representation of differentially expressed gene by E. coli O157:H7 strain NADC 6564 in response to norepinephrine (A) A pie chart showing proportion of significantly upregulated (dark blue slice), downregulated (light blue slice), and unaffected genes (red slice) in total of 5509 chromosomal genes analyzed by RNA-Seq, (B) A bar graph showing number of upregulated genes with known function (dark blue bar), upregulated genes assigned hypothetical function (light blue bar), downregulated genes (dark green bar), and downregulated genes assigned hypothetical function (light green bar). Inset Table in Fig. 1 shows up- and downregulated genes of known and hypothetical functions and their fold change in expression, and (C) BRIG plot showing distribution of upregulated genes (green), downregulated genes (red), Genomic islands 1–53 (blue) and bacteriophages P1 – P19 (purple) on the chromosome of strain NADC 6564. Chromosomal size (5,466,770 bp) of strain NADC 6564 is listed in the center of the inner circle, which is marked on the inside using a 500 kbp (kilo base pairs) scaleBack to article page
