Genomic evidence for ameiotic evolution in the bdelloid rotifer Adineta vaga
TLDR
The genome of a bdelloid rotifer, Adineta vaga, is reported and it is shown that its structure is incompatible with conventional meiosis, and abundant evidence of gene conversion is found, which may limit the accumulation of deleterious mutations in the absence of meiosis.
Leukocyte Ig-like receptor complex (LRC) in mice and men.
TLDR
The architecture of membrane receptors with extracellular Ig- like domains located within the leukocyte Ig-like receptor complex (LRC) of humans and mice is compared and evolutionary associations between these receptors and their domains are examined.
Evidence of en bloc duplication in vertebrate genomes
TLDR
Phylogenetic analysis of 31 genes in the major histocompatibility complex paralogous regions of amphioxus shows that duplications occurred after the divergence of cephalochordates and vertebrates but before the Gnathostomata radiation.
The phylogenetic analysis of tetraspanins projects the evolution of cell-cell interactions from unicellular to multicellular organisms.
TLDR
The study of tetraspanin in a phylogenetic context helps to understand the evolution of intercellular interactions and it is suggested that t Petraspanins play important roles in the unicell-to-multicell transition.
Myelin/oligodendrocyte glycoprotein is a member of a subset of the immunoglobulin superfamily encoded within the major histocompatibility complex.
TLDR
It is shown that the developmental pattern of MOG expression in the rat central nervous system coincides with the late stages of myelination, and the homology between MOG and B-G extends beyond their structure and genetic mapping to their ability to induce strong antibody responses and has implications for the role of Mog in pathological, autoimmune conditions.
Gene evolution and gene expression after whole genome duplication in fish: the PhyloFish database
TLDR
The PhyloFish database is developed to provide de novo assembled gene repertoires in 23 different ray-finned fish species including two holosteans and 21 teleosts and to obtain the most exhaustive gene repertoire possible in each species that allows between-species comparisons to study the evolution of gene expression in different lineages.
Massive comparative genomic analysis reveals convergent evolution of specialized bacteria
TLDR
It is shown that obligate intracellular bacteria from different phyla are converging according to their lifestyle, and gene loss, rather than acquisition of virulence factors, has been a driving force in the adaptation of parasites to eukaryotic cells.
Nme protein family evolutionary history, a vertebrate perspective
TLDR
The present study offers an evolutionary framework that will pave the way for future studies on vertebrates Nme proteins and provides a unified vertebrate Nme nomenclature that is consistent with the nomenClature in use in mammals.
GPR50 is the mammalian ortholog of Mel1c: Evidence of rapid evolution in mammals
TLDR
There are only three members in the melatonin receptor subfamily with one of them undergoing rapid evolution from fishes and birds to mammals, and GPR50 is the ortholog of the high affinity Mel1c receptor.
Decelerated genome evolution in modern vertebrates revealed by analysis of multiple lancelet genomes
TLDR
It is suggested, through comparison with multiple lancelet genomes, that ancient vertebrates experienced high rates of protein evolution, genome rearrangement and domain shuffling and that these rates greatly slowed down after the divergence of jawed and jawless vertebrates.
