Sequence variation at the major histocompatibility complex locus DQ beta in beluga whales (Delphinapterus leucas)
TLDR
Although the amount of allelic variation is low when compared with terrestrial mammals, the nature of the substitutions in the peptide binding sites indicates an important role for the DQ beta locus in the cellular immune response of beluga whales. Expand
The effect of hypoxia on gill morphology and ionoregulatory status in the Lake Qinghai scaleless carp, Gymnocypris przewalskii
TLDR
The hypothesis that gill remodeling during hypoxia is a general characteristic of cold water carp species is supported, although the reduced magnitude of the response in scaleless carp relative to goldfish and crucian carp may be a reflection of their more active lifestyle or because they reside in a moderately hypoxic environment at altitude. Expand
A Contig Map of the Mhc Class I Genomic Region in the Zebrafish Reveals Ancient Synteny
TLDR
In the zebrafish, Danio rerio, the clusters of class I and class II loci reside in different linkage groups, which has implications for the persistence of syntenic relationships, coevolution of loci, and interpretation of the origin of the human/mouse Mhc organization. Expand
Population differentiation in the franciscana (Pontoporia blainvillei) from two geographic locations in Brazil as determined from mitochondrial DNA control region sequences
TLDR
Reconstruction of the phylogenetic relationships among the haplotypes through a maximum-likelihood analysis of sequences revealed two distinct lineages that were consistent with the geographic sampling patterns of the franciscana. Expand
Dogmas and controversies in the handling of nitrogenous wastes: Expression of arginase Type I and II genes in rainbow trout: influence of fasting on liver enzyme activity and mRNA levels in juveniles
TLDR
Comparison of vertebrate arginase sequences shows that both Type I and Type II genes in bony fishes contain a mitochondrial targeting N-terminal domain, which suggests that the cytosolic Type IArginase found in ureotelic vertebrates arose in the common ancestor of amphibia and mammals. Expand
Evolution of glutamine synthetase in vertebrates: multiple glutamine synthetase genes expressed in rainbow trout (Oncorhynchus mykiss)
TLDR
Evidence of four expressed GSase mRNAs for the tetraploid rainbow trout implies that the trout genes are encoded by at least four separate loci, belonging to two distinct evolutionary branches, and supports the idea that fish GSases are polyphyletic. Expand
Sequence variation at the major histocompatibility complex DRB loci in beluga (Delphinapterus leucas) and narwhal (Monodon monoceros)
TLDR
Data are consistent with an important role for the DRB1 locus in the cellular immune response of beluga, and the ratio of nonsynonymous to synonymous substitutions is similar to that among primate alleles, arguing against a reduction in the balancing selection pressure in the marine environment. Expand
Mitochondrial cytochrome b variation in sleeper sharks (Squaliformes: Somniosidae)
TLDR
Analysis of genetic structure within the S. pacificus/antarcticus clade showed limited or no differences amongst three populations, strongly supporting the distinction of S. microcephalus as a separate species from the Pacific sleeper shark species. Expand
Nonlinkage of major histocompatibility complex class I and class II loci in bony fishes
TLDR
It is suggested that in all Euteleostei, the classical class’I and class II B loci are in separate linkage groups, and that in at least some of these taxa, the class”II locu are in two different groups. Expand
