Figure S2.
The tree includes various branches labeled with different gene groups such as Plant GLRs, Cnidarian AKDF genes, Bilaterian Delta genes, and others. Each branch is supported by SH-aLRT and ultrafast bootstrap values indicated at the nodes. The tree is divided into two main clusters labeled Kainate and AMPA, showing the divergence of these gene groups. The diagram illustrates the evolutionary history and relationships of iGluR sequences across different species.
Animal iGluR gene tree (untrimmed alignment). Maximum likelihood tree based on untrimmed alignment (Data S3 and S4), including gaps and variable regions, of the same 388 iGluR sequences as Fig. S1 (see Materials and methods, Molecular phylogenetics). Branch support values are SH-aLRT and ultrafast bootstrap.
