Phylogenetic reconstruction of phage and GI integrases against 186 homologues from viruses.

<p><i>Xylella</i> phage and GI integrases are represented by black diamond-shaped symbols. Distance tree computed by the neighbor-joining method, using the JTT matrix-based method. The dotted lines, and the letters inside, indicate the position of each <i>Xylella</i> integrase sub-families (see text for further information).</p>
