Class Ia RNR protein phylogenies.
Phylogenetic trees constructed by the Maximum likelihood method (PhyML) based on the
aligned amino acid sequences of a)nrdA
. In both trees the collapsed clades include
(Aeh1, phiAS5, and PX29),
(25, 31, 44RR2.8 t, and phiAS4),
(SPO1 and 0305phi8-36),
(CP220 and Cpt10),
phages P-HM1, P-HM2, P-RSM4, P-SSM2, P-SSM4, P-SSM7, Synechococcus
phages S-CRM01, S-PM2, S-RSM4, S-ShM2, S-SM1, S-SM2, S-SSM5, S-SSM7, syn1, syn9, syn19,
(133, Acj61, and Acj9),
Enterobacteria phage cluster 1
(JS98, JS10, and IME08),
Enterobacteria phage cluster 2
(RB49, Phi1, and JSE),
Enterobacteria phage cluster 3
(RB16 and RB43),
Enterobacteria phage cluster 4
(EPS7, SPC35, and T5),
(phiEa 104 and phiEa-214),
(P100 and A511), and
). The phages and bacterial hosts (both taxon labels and nodes) are color coded in
green and red, respectively. The bootstrap values are shown for nodes with ≥ 70% support.
The scale bar represents the number of amino acid substitutions per site.
