“…Morphologically, Cyprininae includes four subgroups, such as barbine, cyprinine, labeonine and schizothoracine, referred as four subfamilies by Chen (Chen, 1998). Wild species of Cyprininae fish vary greatly in ploid levels ranging from diploids (2n=50) to high polyploids (2n=417-470) (Arai, 2011;Buth et al, 1991;Leggatt and Iwama, 2003;Yu et al, 1987Yu et al, , 1989. Examples of polyploidy are commonly observed in barbine, especially in cyprinine and schizothoracine.…”

Origin and diversification of the Tibetan polyploid cyprinids (schizothoracins) may help us to explore relationships between diversification of the cyprinids and the Tibetan Plateau uplift. Cyprininae phylogeny was analyzed using mitochondrial and nuclear DNA sequences to trace origins of polyploidy and diversifications of schizothoracins. Ancestral states reconstruction for ploidy levels indicated that the Cyprininae was diploid origin and the schizothoracin clades tetraploid origins. There were two diversification rate shifts along with diversification of the cyprinine fishes in response to the Tibetan uplift. The unusual diversification shifts were located to branches subtending the clades of Tibetan polyploid cyprinids. Our analyses suggested that (i) phylogeny of Cyprininae recovered two independent origins of the Tibetan polyploidy schizothoracins; (ii) diversifications of the schizothoracins were closely related to the Neogene uplift of the Tibetan plateau in the following ways: the relatively ancient Late Oligocene-Middle Miocene adaptive radiation may be associated with the uplift of the southern Tibet and Himalaya; the Middle Miocene-Early Pleistocene lineage-specific diversification broadly coincident with major phase of the Neogene Tibetan uplift; and the most recent Pleistocene diversification shift in Schizothorax closely coincident with the successive Kunlun-Huanghe and Gonghe movements of the Tibetan uplift and the glaciation-induced climate oscillations on the plateau.Cyprininae, polyploid, schizothoracins, the Tibetan Plateau, diversifications Citation:Wang, X., Gan, X., Li J., Chen, Y., and He, S.

“…Multiple NOR phenotypes of A. marmid with major ribosomal sites located on two pairs of chromosomes is derived from an ancestral leuciscine NOR phenotype via rearrangements of fission/translocation type. In any case, our results indicate that NOR phenotypes of leuciscine cyprinids exemplified above may be as variable as those found in North American (Buth et al, 1991) or Asian cyprinids (Takai & Ojima, 1992).…”

Note on the karyotype and NOR phenotype of leuciscine fish Acanthobrama marmid (Osteichthyes, Cyprinidae)

The karyotype and major ribosomal sites as revealed using silver staining of Anatolian leuciscine cyprinid fish Acanthobrama marmid were studied. The diploid chromosome number was invariably 2n = 50. Karyotype consisted of eight pairs of metacentric, 13 pairs of submetacentric and four pairs of subtelocentric to acrocentric chromosomes. The largest chromosome pair of the complement was subtelo-to acrocentric characteristically, which is a characteristic cytotaxonomic marker for representatives of the cyprinid lineage Leuciscinae. The nucleolar organizer regions (NORs) were detected in the telomeres of two pairs of medium sized submeta-to subtelocentric chromosomes. No heteromorphic sex chromosomes were found. The karyotype pattern of A. marmid is nearly identical to that found in most other representatives of the Eurasian leuciscine cyprinids, while the multiple NOR phenotype appears to be more derived as opposed to a uniform one, ubiquitous in this group.

“…This model reopened the discussion about the primitive chromosome number in the family and assumed that «diploïdy» should be considered as an apomorphic state conversely to the orthodox theory, that points out that the derived stage is the 2n=100 karyotype (see BUTH et al, 1991 ).…”

RÉSUMÉLe modèle d'évolution caryologique des Cyprinidés, selon lequel le nombre polyploïde 2n=100 doit être considéré comme plésiomorphe pour la famille, en opposition à la théorie orthodoxe, semble se vérifier par la publication récente de nouvelles données concernant les nombres chromosomiques de Cyprininés d'Afrique et d'Asie du sud. L'hypothèse d'un ancêtre de type Cyprininé, appartenant probablement à une lignée proche des Barbinés, ainsi que l'existence d'une polyploïdie fonctionnant comme un «système-ouvert» est suggérée sur la base de caractères caryoévolutifs. L'importance de ce phénomène dans le processus évolutif de quelques lignées justifie un appel à l'inclusion future de l'information caryologique dans les travaux de systématique évolutive. En effet, les progrès actuels en cytogénétique moléculaire, en rendant possible la reconnaissance d'homologies chromosomiques interspécifiques, permettront probablement de clarifier les relations phylogénétiques au sein même des Cypriniformes.Mots-clés : Polyploïdie, évolution caryologique, Cyprinidés, Cyprininés, Barbus. ABSTRACTThe new model of karyological evolution of Cyprinidae which proposes that the polyploid value 2n=100 should be regarded as plesiomorphic for the family, contrary to the orthodox theory, seems to be reinforced by some new data on chromosome numbers of African and South-Asian cyprinins. So, the hypothesis of a cyprinin-like ancestor, probably close to the barbin lineage, with polyploidy acting as an «open-system» in the karyoevolution of cyprinids, is suggested. The important role of this phenomenon in the evolutionary process of some lineages seems to be unquestionable and, in this sense, it is proposed that systematists should give more attention to karyological data in the establishment of their classification schemes, Besides, technological advances in molecular cytogenetics will provide important tools for the revision of the hierarchical levels used in the classification of Cyprinidae and, possibly, for the recognition of phylogenetic relationships within cypriniforms.
