The shortnose sturgeon Acipenser brevirostrum was revealed to have a larger number of chromosomes than previously reported for other sturgeon species. Its chromosome number ranged from 362 to 372 (of ten specimens examined), showing intraindividual variation. The karyotype of metaphase with the highest chromosome number (372) consisted of 89 pairs of macrochromosomes and 97 pairs of microchromosomes (fundamental number; NF = 550). Although the microchromosomes were relatively shorter than the… Expand

Evidence of hexaploid karyotype in shortnose sturgeon.
TLDR
Results support the hypothesis that A. brevirostrum is a hexaploid species, probably of hybrid origin, and a model explaining speciation events occurring in sturgeons by hybridization, genome duplication, and diploidization is proposed. Expand
How many times has polyploidization occurred during acipenserid evolution? New data on the karyotypes of sturgeons (Acipenseridae, Actinopterygii) from the Russian Far East
TLDR
All western Pacific sturgeon species are from a tetraploid origin, based on a recent ploidy scale, which suggests that at least three polyploidization events have occurred during the evolution of Acipenseridae. Expand
The blue butterfly Polyommatus (Plebicula) atlanticus (Lepidoptera, Lycaenidae) holds the record of the highest number of chromosomes in the non-polyploid eukaryotic organisms
TLDR
It is demonstrated that Polyommatus atlanticus is a diploid (non-polyploid) species, its meiotic I chromosome complement includes at least 224-226 countable chromosome bodies, and all (or nearly all) chromosome elements in meiotics I karyotype are represented by bivalents. Expand
Development of polysomic microsatellite markers for characterization of population structuring and phylogeography in the shortnose sturgeon (Acipenser brevirostrum)
TLDR
In the range-wide survey, a Mantel comparison of an ecological and genetic distance metrics, identified a strong positive correlation, suggesting ΦPT represents a viable metric for assessing genetic relatedness using this class of marker. Expand
The karyotype of the Amu Darya sturgeon, Pseudoscaphirhynchus kaufmanni (Actinopterygii: Acipenseriformes: Acipenseridae)
The order Acipenseriformes is an ancient group of vertebrate animals represented by two fossil families: Peipiaosteidae, extending back to the Upper Jurassic, and Chondrosteidae, dating from theExpand
Sturgeon genetics and cytogenetics: a review related to ploidy levels and interspecific hybridization
TLDR
The major aspects of sturgeon genetics and cytogenetics related to ploidy levels and interspecific hybridization, and Identification of parental species of natural hybrids by modern methods of molecular biology, are summarized. Expand
Artificial whole genome duplication in paleopolyploid sturgeons yields highest documented chromosome number in vertebrates
TLDR
It is demonstrated that the sturgeon genome can undergo numerous alterations of ploidsy without severe physiological consequences, producing progeny with a range of ploidy levels and extremely high chromosome numbers. Expand
Genome size variation estimated by flow cytometry in Acipenser mikadoi, Huso dauricus in relation to other species of Acipenseriformes
Summary In Acipenseriformes, extant species can be categorized into three ploidy groups based on their genome size inferred from chromosome numbers and/or nuclear DNA content. However, genome sizeExpand
Chromosome Distribution of Highly Conserved Tandemly Arranged Repetitive DNAs in the Siberian Sturgeon (Acipenser baerii)
TLDR
It is demonstrated that the last genome duplication event in the Siberian sturgeon was accompanied by the simultaneous expansion of several repetitive DNA families that serve as good cytogenetic markers distinguishing paralogous chromosomes and detecting ancestral syntenic regions. Expand
Evolution of Polyploidy and Functional Diploidization in Sturgeons: Microsatellite Analysis in 10 Sturgeon Species.
TLDR
It is proposed that the evolution of sturgeons has been affected by at least 3 different polyploidization events, which could be explained by the more recent genome duplication in tetraploid species from the Atlantic clade. Expand

TLDR
An improved C-banding technique revealed variation between animals in the number of entirely heterochromatic metacentric chromosomes that may represent supernumerary chromosomes in the North American white sturgeon. Expand

TLDR
The A. sturio karyotype organization is discussed in relation to phylogenesis of the species within the Acipenseridae and to polyploidization events characterizing sturgeon evolution. Expand
Karyotypic characterization of the great sturgeon, Huso huso, by multiple staining techniques and fluorescent in situ hybridization
TLDR
A karyotype analysis by several staining techniques was carried out on the great sturgeon, Huso huso, finding thatConstitutive heterochromatin was mainly located at the centromeric regions of the acrocentric chromosomes. Expand

TLDR
Results suggest that gene silencing, chromosomal rearrangements, and transposition events played an important role in the acipenseriform genome formation and reveal a highly supported oceanic subdivision within the Acipenser/Huso complex. Expand
Phylogeny of the Acipenseriformes: cytogenetic and molecular approaches
TLDR
The phylogeny based on molecular analysis had two major departures from existing morphological hypotheses: Huso dauricus is a sister-species to Acipenser instead of being basal to all acipenseriforms, and Scaphirhynchus and Pseudoscaphirchus do not form a monophyletic group. Expand

TLDR
A karyotypic analysis was carried out on the Russian sturgeon using C‐ and Ag‐NOR banding techniques and base specific DNA‐binding fluorochromes and interspersion of the opposite DNA base pairs along the chromosomes is discussed. Expand
Karyotype of the American Green Sturgeon
TLDR
The first karyological analysis of the rare American green sturgeon Acipenser medirostris found a mean chromosome number of 249 ± 8 (range, 234–263) with both between- and within-animal variation in chromosome number. Expand
Chromosomal nucleolar organizer regions in four sturgeon species as markers of karyotype evolution in Acipenseriformes (Pisces).
TLDR
Nucleolar organizer regions in Acipenser ruthenus and A. baeri are localized on the telomeric regions of two morphologically different pairs of chromosomes, which suggests that species with 120 chromosomes should be considered diploids and species with 240-250 chromosomesShould be considered tetraploid.

TLDR
Diploid and triploid hybrids between mud loach and cyprinid loaches and their reciprocal hybrids were produced by artificial fertilization and by cold shocks and had lower hatching and early survival than their diploid counterparts. Expand
