Abstract Background Java combtail fish Belontia hasselti (Cuvier, 1831), a member of the Osphronemidae family, inhabits lakes and rivers throughout Southeast Asia Sri Lanka. Previous cytogenetic research revealed it possesses diploid chromosome number 48 chromosomes with female-heterogametic ZZ/ZW sex system, where W is distinguishable as only metacentric element in complement. Female-heterogametic systems seem to be otherwise surprisingly rare highly diverse order Perciformes and,...

Chromosomal evolution in carnivores has been revisited extensively using cross-species chromosome painting. Painting probes derived from flow-sorted chromosomes of the domestic dog, which one most rearranged karyotypes mammals and highest dipoid number (2n=78) carnivores, are a powerful tool detecting both evolutionary intra- inter-chromosomal rearrangements. However, only few comparative maps have established between dog other non-Canidae species. Here, we extended painting with to seven...
Channid fishes, commonly referred to as “snakeheads”, are currently very important in Asian fishery and aquaculture due the substantial decline natural populations because of overexploitation. A large degree chromosomal variation has been found this family, mainly through use conventional cytogenetic investigations. In study, we analyzed karyotype structure distribution 7 repetitive DNA sequences several Channa species from different Thailand river basins. The aim study was investigate...
Synbranchidae or swamp eels are fishes belonging to the order Synbranchiformes that occur in both freshwater and occasionally brackish. They worldwide distributed tropical subtropical rivers of four different continents. A large degree chromosomal variation has been found this family, mainly through use conventional cytogenetic investigations. Inside group, a still almost unexplored species under point view is Asian eel Monopterus albus, widely throughout Asia. Here, we tested hypothesis...
The Labeoninae subfamily is a highly diversified but demonstrably monophyletic lineage of cyprinid fishes comprising five tribes and six incertae sedis genera. This widely distributed assemblage contains some 48 genera around 480 recognized species in freshwaters Africa Asia. In this study, the karyotypes other chromosomal properties found Thailand Labeo chrysophekadion (Labeonini) Epalzeorhynchos bicolor , munense Henicorhynchus siamensis Thynnichthys thynnoides (´Osteochilini´) were...
Abstract Background Flying lemurs or Colugos (order Dermoptera) represent an ancient mammalian lineage that contains only two extant species. Although molecular evidence strongly supports the orders Dermoptera, Scandentia, Lagomorpha, Rodentia and Primates form a superordinal clade called Supraprimates (or Euarchontoglires), phylogenetic placement of Dermoptera within remains ambiguous. Results To search for cytogenetic signatures could help to clarify evolutionary affinities this group, we...
In the present study, conventional and molecular cytogenetic studies were performed in naked catfish Mystus bocourti (Siluriformes, Bagridae). Besides Giemsa staining, fluorescence situ hybridization (FISH) using nine classes of repetitive DNAs namely 5S 18S rDNAs, U2 snRNA, microsatellites (CA)15 (GA)15, telomeric repeats, retrotransposable elements Rex1, 3 6. was also performed.M. had 2n = 56 chromosomes with a karyotype composed by 11 m + sm 6 st/a fundamental number (NF) equal to 100...
The genus Clarias (Clariidae, Siluriformes) contains at least 61 species naturally spread over vast regions of Asia, India and Africa. However, have also been introduced in many different countries represent the most widespread catfishes world. These fishes are known as "walking catfishes" due to their ability move land. A large degree chromosomal variation has previously found this family, mainly using conventional cytogenetic investigations, with diploid chromosome numbers ranging between...
Osteoglossiformes represents one of the most ancestral teleost lineages, currently widespread over almost all continents, except for Antarctica. However, data involving advanced molecular cytogenetics or comparative genomics are yet largely limited this fish group. Therefore, present investigations focus on osteoglossiform family Arapaimidae, studying a unique model group with cytogenetic genomic tools. The aim is to better explore and clarify certain events factors that had impact...
Arowanas (Osteoglossinae) are charismatic freshwater fishes with six species and two genera (Osteoglossum Scleropages) distributed in South America, Asia, Australia. In an attempt to provide a better assessment of the processes shaping their evolution, we employed set cytogenetic genomic approaches, including i) molecular analyses using C- CMA3/DAPI staining, repetitive DNA mapping, comparative hybridization (CGH), Zoo-FISH, along ii) genotypic single nucleotide polymorphisms (SNPs)...
Scleropages formosus (Osteoglossiformes, Teleostei) represents one of the most valued ornamental fishes, yet it is critically endangered due to overexploitation and habitat destruction. This species encompasses three major color groups that naturally occur in allopatric populations, but evolutionary taxonomic relationships S. varieties remain uncertain. Here, we utilized a range molecular cytogenetic techniques characterize karyotypes five phenotypes, which correspond occurring variants: red...
The cytogenetics of the ornamented pygmy frog (Microhyla fissipes), painted chorus (M. pulchra) and narrow-mouthed heymonsi) were studied in aspect chromosome numbers, morphology nucleolus organizer region (NOR) locations. For this present study, we provided karyotype idiogram these three species by conventional Ag-NOR staining techniques. 10 male female samples those collected Northeast Thailand. metaphase preparations prepared from bone marrows standard protocol. To stain chromosomes, 10%...
In addition to its wide geographical distribution, osteoglossiform fishes represent one of the most ancient freshwater teleost lineages; making it an important group for systematic and evolutionary studies. These had a Gondwanan origin their past distribution may have contributed diversity present in this group. However, cytogenetic genomic data are still scarce, difficult track trajectories within order. addition, with groups endemic different continents, hinders integrative study that...
Chromosome preparation from gill tissue of the tropical oyster (Crassostera belcheri Sowerby, 1871) collected an farm in Kantang District, Trang Province, southern Thailand was studied by conventional staining and Ag-NOR baining techniques. The result revealed that diploid chromosome number is 2n=20 fundamental (NF) 40. karyotype has 10 large metacentric medium chromosomes. One pair nucleolar organizer regions (NORs) apparent on short arm telomeric region 10. Basic information cytogenetics...
Abstract Notopteridae (Teleostei, Osteoglossiformes) represents an old fish lineage with ten currently recognized species distributed in African and Southeastern Asian rivers. Their karyotype structures diploid numbers remained conserved over long evolutionary periods, since lineages diverged approximately 120 Mya. However, a significant genetic diversity was already identified for these using molecular data. Thus, why the relationships within are so diverse at genomic level but terms of...
The representatives of cyprinid lineage 'Poropuntiinae' with 16 recognized genera and around 100 species form a significant part Southeast Asian ichthyofauna. Cytogenetics are valuable when studying fish evolution, especially the dynamics repetitive DNAs, such as ribosomal DNAs (5S 18S) microsatellites, that can vary between species. Here, karyotypes seven 'poropuntiin' species, namely Cosmochilus harmandi, Cyclocheilichthys apogon, Hypsibarbus malcomi, H. wetmorei, Mystacoleucus...
