The Arctic and Antarctic marine faunas differ by age and isolation. Fishes of the two polar regions have undergone different regional histories that have driven the physiological diversities. Antarctic fish are highly stenothermal, in keeping with stable water temperatures, whereas Arctic fish, being exposed to seasonal temperature variations, exhibit higher physiological plasticity. This study reports the characterization of the oxygen transport system of three Arctic species of the family Gadidae, namely the Arctic cod Arctogadus glacialis, the polar cod Boreogadus saida, and the Atlantic cod Gadus morhua. Unlike Antarctic notothenioids, the blood displays high multiplicity, i.e. it has three hemoglobins, similar to many other acanthomorph teleosts. In the most abundant hemoglobin, oxygen binding is modulated by heterotropic effectors, with marked Bohr and Root effects. Remarkably, in two species (A. glacialis and B. saida), the Hill coefficient is very close to one in the whole pH range, indicating the apparent absence of cooperativity. The amino acid sequences have been used to gain insight into the evolution history of globins of polar fish. The results indicate that Arctic and Antarctic globins have different phylogenies and lead us to suggest that the selective pressure of environment stability allows the phylogenetic signal to be maintained in the Antarctic sequences, whereas environmental variability would tend to disrupt this signal in the Gadidae sequences.The main differences between the Arctic and the Antarctic are the older age and longer isolation of the latter (1). The Antarctic has been isolated and cold longer than the Arctic, with ice-sheet development preceding that in the Arctic by at least 10 million years. In a recent review, Eastman (2) wrote the following. "The Antarctic experienced a slow and discontinuous transition from a warm-water system in the early Tertiary (15°C) to the cold-water system of today (Ϫ1.87°C). The first glaciation, including shelf-ice formation, had occurred 36 million years ago (mya) 2 in the early Oligocene. About 25 mya, the formation of the Polar Front, which followed the opening of the Drake passage, further isolated the Antarctic marine fauna from the world ocean. Although Europe began to separate from Greenland in the late Cretaceous, the exchange of Atlantic and Arctic waters through the passage between Greenland and the Svalbard islands was not possible until 27 mya. The Arctic region was in a high latitude position by the early Tertiary, but the climate remained temperate with water temperatures of 10 -15°C. Arctic land masses reached their present positions, and temperatures dropped below freezing during the Miocene about 10 -15 mya."The Antarctic and Arctic fish faunas differ in age, endemism (denoting species native to a given geographical area), and taxonomic diversity. In the southern ocean, the fauna includes 322 species grouped in 50 families (3), whereas the Arctic fauna has 416 species of 96 families. In the Antarctic, endemism reaches 88% and ris...

“…The obtained topology is in general agreement with the hypothesis of four groups of globins, namely 'Embryonic or Minor Hb Group', 'Notothenioid Major Adult Hb Group', 'Anodic Adult Hb Group' and 'Cathodic Adult Hb Group' (36). The position of the C. gobio and P. urvillii globins is in agreement with phylogenetic evidence from nuclear and mitochondrial genes, according to which C. gobio was the first species to diverge from notothenioids, before P. urvillii [reviewed in (27)].…”

The adaptation of polar fishes to climatic changes: Structure, function and phylogeny of haemoglobin

2007

In the Antarctic, fishes of dominant suborder Notothenioidei have evolved in a unique thermal scenario. Phylogenetically related taxa of the suborder live in a wide range of latitudes, in Antarctic, sub‐Antarctic and temperate oceans. Consequently, they offer a remarkable opportunity to study the physiological and biochemical characters gained and, conversely, lost during their evolutionary history. The evolutionary perspective has also been pursued by comparative studies of some features of the heme protein devoted to O2 transport in fish living in the other polar region, the Arctic. The two polar regions differ by age and isolation. Fish living in each habitat have undergone regional constraints and fit into different evolutionary histories. The aim of this contribution is to survey the current knowledge of molecular structure, functional features, phylogeny and adaptations of the haemoglobins of fish thriving in the Antarctic, sub‐Antarctic and Arctic regions (with some excursions in the temperate latitudes), in search of insights into the convergent processes evolved in response to cooling. Current climate change may disturb adaptation, calling for strategies aimed at neutralising threats to biodiversity. © 2007 IUBMB IUBMB Life, 60(1): 29–40, 2008

“…Five pairs of the α-and β-globin genes were found to be organized in a head-to-head orientation. We named the paired globin genes based on the head-to-head orientation because in the phylogenic analysis, we found that the gene pair seemed to have coevolved (Maruyama et al 2004b). …”

“…In the previous phylogenetic analysis, we showed that teleost globin genes could be classified into four groups, group I (embryonic Hb), group II (notothenioid major adult Hb), group III (anodic adult Hb), and group IV (cathodic adult Hb) (Maruyama et al 2004b). Group I Hb is embryonic and has a high oxygen affinity and no or little Bohr effect; group II Hb is found mainly in adult Antarctic fish; group III Hb is generally used in adult fishes such as carp, rainbow trout, zebrafish, and yellowtail; and group IV Hb has a low oxygen affinity, high Bohr effect, and Root effect and is found in fishes, such as eel, rainbow trout, and salmon.…”

“…However, the α5(ψα) and β5(ψβ) genes that belonged to group III were pseudogenized and not expressed. By modifying the β5(ψβ) gene with some insertions and deletions (i.e., adding two bases and deleting two bases), we predicted an open reading frame and a translated amino acid sequence (Maruyama et al 2004b). These findings suggested that the Hd-rR strain of medaka had a functional group III globin until a relatively late stage of evolution and that the group III gene was pseudogenized and broken after the introduction of point mutations.…”

Hemoglobin transports oxygen in many organisms and consists of α- and β-globin chains. Previously, using molecular phylogenetic analysis, we proposed that both α- and β-globins of teleost could be classified into four groups. We also showed that the Hd-rR strain of medaka (Oryzias latipes) inhabiting southern Japan had all four groups of globin genes but that the α- and β-globin genes of group III were pseudogenized (α5(ψα), β5(ψβ)). Based on the small degree of nucleotide variations, the pseudogenization of β5 was assumed to have occurred at a relatively late stage of evolution. Here, we compared the α5(ψα)-β5(ψβ) of two other strains of O. latipes and found that both α5(ψα) and β5(ψβ) of the northern Japanese and Korean strains were pseudogenized similar to those of Hd-rR. In a Philippine population (Oryzias luzonensis), α5(ψα) was also pseudogenized, but the structure was different from that of O. latipes, and β5(ψβ) was almost deleted. Interestingly, an Indonesian population (Oryzias celebensis) had α5 and β5 genes that were deduced to be functional. Indeed, they were expressed from the young to adult development stages, and this expression pattern was consistent with the expression of α2 and ad.α1 in Hd-rR. Because α2 and ad.α1 in Hd-rR were assigned to groups I and II, respectively, we speculate that their expression patterns might be altered by pseudogenization of group III genes. These results provide a basis for further investigations of recruiting and changing expression patterns of one globin gene after pseudogenization of other globin genes during evolution.
