Phylogenomics: Gene Duplication, Unrecognized Paralogy and Outgroup Choice
Comparative genomics has revealed the ubiquity of gene and genome duplication and subsequent gene loss. In the case of gene duplication and subsequent loss, gene trees can differ from species trees, thus frequent gene duplication poses a challenge for reconstruction of species relationships. Here I address the case of multi-gene sets of putative orthologs that include some unrecognized paralogs...
متن کاملParalogy and orthology in the MALVACEAE rpb2 gene family: investigation of gene duplication in hibiscus.
A sample of the second largest subunit of low-copy nuclear RNA polymerase II (rpb2) sequences from Malvaceae subfamily Malvoideae suggests that rpb2 has been duplicated early in the subfamily's history. Hibiscus and related taxa possess two rpb2 genes, both of which produce congruent phylogenetic patterns that are largely concordant with cpDNA topologies. No evidence of functional divergence or...
متن کاملVertebrate Phylogenomics: Reconciled Trees and Gene Duplications
Ancient gene duplication events have left many traces in vertebrate genomes. Reconciled trees represent the differences between gene family trees and the species phylogeny those genes are sampled from, allowing us to both infer gene duplication events and estimate a species phylogeny from a sample of gene families. We show that analysis of 118 gene families yields a phylogeny of vertebrates lar...
متن کاملGene duplication and evolution.
Lynch and Conery (1) presented one of the first serious efforts to study the evolutionary fate of gene duplication using genomic sequence data. Their analysis led to several interesting observations, particularly with respect to the rate of gene duplication in eukaryotic genomes and the subsequent halflife of duplicates. These two parameters are of particular importance in studying the evolutio...
متن کاملGene and genome duplication.
Genomic sequencing projects have revealed the productivity of processes duplicating genes or entire chromosome segments. Substantial proportions of the yeast, Arabidopsis and human gene complements are made up of duplicates. This has prompted much interest in the processes of duplication, functional divergence and loss of genes, has renewed the debate on whether an early vertebrate genome was t...
