Summary

Description

Duplications and losses in NR evolution.

(A) Reconciliation of NR gene family phylogeny with the species tree shown in panel B. The phylogeny is rooted to minimize the total number of gene duplications and losses; each branch is labeled with the number of additional duplications and losses required for the tree to be rooted on that branch. Gene duplications are shown as green circles, gene losses as Xs, and speciation events as yellow shapes (circles, split of demosponges from eumetazoans; squares, split of placozoans from eumetazoans (s.s.); diamonds, split of cnidarians from bilaterians). Colors of gene names indicate the taxon from which they are derived, using the color scheme in panel B. (B) Gene duplication history implied by the reconciled tree in panel A. Green bars, duplications; red bars, losses. Duplications are labeled with the named NR lineages they generated. The NR1/NR4/INR ortholog lost in the placozoans (marked *) was generated in the duplication marked **. The large bar comprises numerous duplications that cannot be temporally ordered.
