Growth rates were determined from a fit to the exponential portion of the growth curve, extending in all but one case (, glucose minimal medium) through at least four mass doublings
Open symbols refer to growth in MOPS glucose plus required supplements (nicotinate, panthothenate and thiamine; see Methods), while closed symbols represent growth in MOPS glucose defined-rich medium. . growth rates. The values shown are the specific growth rate constants, , calculated as ln2/(doubling time, in h). For comparison, values of 0.5, 1, and 2 correspond respectively to doubling times of 83, 42, and 21 min. The rich medium results are clustered and therefore not labeled; for the minimal medium, the abbreviations used are Eco (), Pmi (), and Vch (). The diagonal line shows where points should fall if mutation has no effect on the growth rate in these media. . Complementation of the low growth rate in the glucose minimal medium described in (A). The dashed lines indicate growth data for the mutant (open circles; 193 min doubling time) and the mutant bearing the vector control (gray circles; 191 min). Remaining lines show the WT (closed circles; 66 min); and the mutant bearing plasmids with the genes from (triangles; 69 min), (squares; 81 min), or (diamonds; 81 min).<p><b>Copyright information:</b></p><p>Taken from "Limited functional conservation of a global regulator among related bacterial genera: Lrp in , and "</p><p>http://www.biomedcentral.com/1471-2180/8/60</p><p>BMC Microbiology 2008;8():60-60.</p><p>Published online 11 Apr 2008</p><p>PMCID:PMC2374795.</p><p></p
