From: Optimized expression of Hfq protein increases Escherichia coli growth
The effect of diverse hfq variants on the growth of wild-type DH5α and ∆hfq DH5α cells. Growth curves of ∆hfq DH5α cells (a) and wild-type DH5α cells (b) when an hfq variant was introduced. Relative growth rate increase (c) and relative cell density increase (d) by the hfq variants. To calculate the relative values, the measured values were compared with that of control cells that did not harbor any hfq variants. * denotes p-value < 0.05 and ** denotes p-value < 0.0001
