Spontaneous and mutagen-induced mutations in <i>nfxB</i>.

<p>The <i>nfxB</i> mutations detected in the wild-type (WT) and mutator strains (<i>mutS</i>, <i>mutT</i>, <i>mutY</i> and <i>mutM</i>), and the WT strain after exposure to the mutagens 2-aminopurine (2AP), cisplatin (CPT) and hydrogen peroxide (HP) are summarized. The percentage of each mutation type relative to the total number of mutations detected for each strain or treatment is plotted using a color code.
