A Transcriptomic-Phylogenomic Analysis of the Evolutionary Relationships of Flatworms

The interrelationships of the flatworms (phylum Platyhelminthes) are poorly resolved despite decades of morphological and molecular phylogenetic studies. The earliest-branching clades (Catenulida, Macrostomorpha, and Polycladida) share spiral cleavage and entolecithal eggs with other lophotrochozoans. Lecithoepitheliata have primitive spiral cleavage but derived ectolecithal eggs. Other orders ...

Analysis of the Evolutionary Relationships of the PDZ Domains

The PDZ domains are well-known globular fold module of many scaffolding proteins. The domains are involved in protein-protein interaction and play a central role in organizing diverse cell signaling assemblies [2]. Recently the motifs of their binding sites have been researched in biochemical and structural studies [1, 3], but it was pointed out the difficulty to classify the PDZ domains on the...

Revealing Mammalian Evolutionary Relationships by Comparative Analysis of Gene Clusters

Many software tools for comparative analysis of genomic sequence data have been released in recent decades. Despite this, it remains challenging to determine evolutionary relationships in gene clusters due to their complex histories involving duplications, deletions, inversions, and conversions. One concept describing these relationships is orthology. Orthologs derive from a common ancestor by ...

Evolutionary relationships among orbiviruses

The genus Orbivirus consists of 12 defined serological groups of arthropod-borne viruses. The taxonomic group was formed following the demonstration that the genome of bluetongue virus consisted of 10 segments of double-stranded RNA. Viruses with morphology and physico-chemical proper­ ties similar to those of bluetongue virus were included in the genus. As viruses representative of each serogr...
