abstract = {Jade perch (Scortum barcoo) is a new teleost in the developing aquaculture freshwater finfish grow-out sector in Australia and China. However, key information on the breeding sex determination system (SDS) remains poorly understood, hampering sex control programs and genetic improvement. In this study, the jade perch SDS was examined by investigating genome-wide single-nucleotide polymorphisms (SNPs) using diversity arrays technology and cytogenetics analysis to identify the genomic variants associated with sex-linked regions. Although the cytogenetic results showed no variation in the chromosomal patterns between males and females, one male-specific locus and 13 male-linked loci were observed, suggesting that jade perch exhibits male heterogametic XX/XY SDS. Male-specific loci on the putative Y sex chromosome were also identified as an extremely small proportion of the genome. A homology search of the SNP loci revealed the male-specific loci were homologous to the Gypsy transposable element. This might be a remnant of an initial accumulation of repeats on the Y chromosome at the early stage of sex chromosome differentiation. The results provide a base for sex control breeding biotechnologies and genetic improvements to promote sexual size dimorphism and other new approaches to improve the commercial value of jade perch. © 2021},

abstract = {Background: The Siamese fighting fish (Betta splendens, also known as the betta) is well known in aquarium markets, and also presents an exciting new research model for studying parental care, aggressive behavior, and cryptically diverse pigmentation. However, concentrated efforts are required, both in the context of conservation biology and in its genetics, to address the problems of ongoing outbreeding depression, loss of biodiversity, and lack of scientific biological information. Objective: The evolutionary dynamics of the betta must be better understood at the genomic scale in order to resolve the phylogenetic status of unrecognized species, develop molecular markers to study variation in traits, and identify interesting sets of genes encoding various bioresource functions. Methods: The recent revolution in multi-omics approaches such as genomics, transcriptomics, epigenomics, and proteomics has uncovered genetic diversity and gained insights into many aspects of betta bioresources. Results: Here, we present current research and future plans in an ongoing megaproject to characterize the betta genome as de novo assemblies, genes and repeat annotations, generating data to study diverse biological phenomena. We highlight key questions that require answers and propose new directions and recommendations to develop bioresource management to protect and enhance the betta genus. Conclusion: Successful accomplishment of these plans will allow the creation of a reference annotated genome and provide valuable information at the molecular level that can be utilized to sustain biodiversity and eco-management of the betta to improve breeding programs for future biomedical research. © 2021, The Genetics Society of Korea.},

abstract = {A substantial portion of the primate genome is composed of non-coding regions, so-called "dark matter", which includes an abundance of tandemly repeated sequences called satellite DNA. Collectively known as the satellitome, this genomic component offers exciting evolutionary insights into aspects of primate genome biology that raise new questions and challenge existing paradigms. A complete human reference genome was recently reported with telomere-to-telomere human X chromosome assembly that resolved hundreds of dark regions, encompassing a 3.1 Mb centromeric satellite array that had not been identified previously. With the recent exponential increase in the availability of primate genomes, and the development of modern genomic and bioinformatics tools, extensive growth in our knowledge concerning the structure, function, and evolution of satellite elements is expected. The current state of knowledge on this topic is summarized, highlighting various types of primate-specific satellite repeats to compare their proportions across diverse lineages. Inter- and intraspecific variation of satellite repeats in the primate genome are reviewed. The functional significance of these sequences is discussed by describing how the transcriptional activity of satellite repeats can affect gene expression during different cellular processes. Sex-linked satellites are outlined, together with their respective genomic organization. Mechanisms are proposed whereby satellite repeats might have emerged as novel sequences during different evolutionary phases. Finally, the main challenges that hinder the detection of satellite DNA are outlined and an overview of the latest methodologies to address technological limitations is presented.},

Three GC-rich cen-satDNA sequences were detected as a 233 bp MALREP-A and a 293 bp MALREP-B localized to all chromosomes, and a 293 bp MALREP-C distributed on eight chromosome pairs. Sequence lengths of MALREP-B and MALREP-C were 60 bp larger than that of MALREP-A, showing partial homology with core sequences (233 bp). Size differences between MALREP-A and MALREP-B/C suggest the possible occurrence of two satDNA families. The presence of an additional 60 bp in MALREP-B/C resulted from an ancient dimer of 233 bp monomers and subsequent mutation and homogenization between the two monomers. All MALREPs showed partial homology with transposable elements (TEs), suggesting that the MALREPs originated from the TEs. The MALREPs might have been acquired in the Asian swamp eel, thereby promoting fixation in the species. © 2020 Elsevier Inc.},

abstract = {Telomeres comprise tandem repeated DNA sequences that protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes, and their lengths might vary with sex and age. Here, age- and sex-related telomere lengths in male and female captive Siamese cobras (Naja kaouthia) were investigated using quantitative real-time polymerase chain reaction based on cross-sectional data. A negative correlation was shown between telomere length and body size in males but not in females. Age-related sex differences were also recorded. Juvenile female snakes have shorter telomeres relative to males at up to 5 years of age, while body size also rapidly increases during this period. This suggests that an accelerated increase in telomere length of female cobra results from sex hormone stimulation to telomerase activity, reflecting sexually dimorphic phenotypic traits. This might also result from amplification of telomeric repeats on sex chromosomes. By contrast, female Siamese cobras older than 5 years had longer telomeres than males. Diverse sex hormone levels and oxidative stress parameters between sexes may affect telomere length. © 2019 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd.},

abstract = {Sterile hybrid animals exhibit spermatogenic disruptions with a decreased number and/or malformation of mature sperm. F 1 hybrid catfish (2n = 55) is an important cultured fish derived from male North African catfish [Clarias gariepinus (Burchell, 1822); 2n = 56] and female bighead catfish [C. macrocephalus (Günther, 1864); 2n = 54]; they are sterile with gametogenic failure in males. Despite the generality of this phenomenon, the spermatogenic phenotype has not been well described and a comprehensive understanding of the genetic basis of the disruption remains elusive. Our observations in the F 1 male hybrid showed abnormal morphology of testes with small size, while meiotic configuration indicated that meiosis succeeded in the early pachytene stage but failed to progress beyond the diplotene-diakinesis stage in primary spermatocytes. This suggests the presence of a number of degenerated spermatocytes. Histological examination recorded no postmeiotic cells and spermatozoa in F 1 male hybrid testes. A high frequency of apoptotic testicular cells was also present in the F 1 male hybrid, as shown by histochemical results for activated Caspase-3 and TUNEL assays. Low expression levels of Caspase-3, p53 and MCL1 (isoform 2), which activate pro-apoptotic signals in the development process, were also observed in both parental species, but significantly high expression levels were observed in the F 1 male hybrid. By contrast, the level of BCL2 expression was very low in the F 1 male hybrid, supporting the state of apoptosis as BCL2 inhibits the actions of pro-apoptotic proteins. These results collectively suggest that sterility in male hybrids is caused by spermatogenic disruptions in the pachytene stage, resulting from the failure of homologous chromosome pairing due to chromosomal incompatibility between parental genomes, and subsequent elimination by apoptosis leading to spermatogenic breakdown in the F 1 male hybrid. © 2019 Elsevier B.V.},

abstract = {Background: Unlike the chromosome constitution of most snakes (2n=36), the cobra karyotype shows a diploid chromosome number of 38 with a highly heterochromatic W chromosome and a large morphologically different chromosome 2. To investigate the process of sex chromosome differentiation and evolution between cobras, most snakes, and other amniotes, we constructed a chromosome map of the Siamese cobra (Naja kaouthia) with 43 bacterial artificial chromosomes (BACs) derived from the chicken and zebra finch libraries using the fluorescence in situ hybridization (FISH) technique, and compared it with those of the chicken, the zebra finch, and other amniotes. Results: We produced a detailed chromosome map of the Siamese cobra genome, focusing on chromosome 2 and sex chromosomes. Synteny of the Siamese cobra chromosome 2 (NKA2) and NKAZ were highly conserved among snakes and other squamate reptiles, except for intrachromosomal rearrangements occurring in NKA2. Interestingly, twelve BACs that had partial homology with sex chromosomes of several amniotes were mapped on the heterochromatic NKAW as hybridization signals such as repeat sequences. Sequence analysis showed that most of these BACs contained high proportions of transposable elements. In addition, hybridization signals of telomeric repeat (TTAGGG)n and six microsatellite repeat motifs ((AAGG)8, (AGAT)8, (AAAC)8, (ACAG)8, (AATC)8, and (AAAAT)6) were observed on NKAW, and most of these were also found on other amniote sex chromosomes. Conclusions: The frequent amplification of repeats might involve heterochromatinization and promote sex chromosome differentiation in the Siamese cobra W sex chromosome. Repeat sequences are also shared among amniote sex chromosomes, which supports the hypothesis of an ancestral super-sex chromosome with overlaps of partial syntenies. Alternatively, amplification of microsatellite repeat motifs could have occurred independently in each lineage, representing convergent sex chromosomal differentiation among amniote sex chromosomes. © 2018 The Author(s).},

abstract = {Background: Satellite DNAs (stDNAs) are highly repeated sequences that constitute large portions of any genome. The evolutionary dynamics of stDNA (e.g. copy number, nucleotide sequence, location) can, therefore, provide an insight into genome organization and evolution. We investigated the evolutionary origin of VSAREP stDNA in 17 monitor lizards (seven Asian, five Australian, and five African) at molecular and cytogenetic level. Results: Results revealed that VSAREP is conserved in the genome of Asian and Australian varanids, but not in African varanids, suggesting that these sequences are either differentiated or lost in the African varanids. Phylogenetic and arrangement network analyses revealed the existence of at least four VSAREP subfamilies. The similarity of each sequence unit within the same VSAREP subfamily from different species was higher than those of other VSAREP subfamilies belonging to the same species. Additionally, all VSAREP subfamilies isolated from the three Australian species (Varanus rosenbergi, V. gouldii, and V. acanthurus) were co-localized near the centromeric or pericentromeric regions of the macrochromosomes, except for chromosomes 3 and 4 in each Australian varanid. However, their chromosomal arrangements were different among species. Conclusions: The VSAREP stDNA family lack homogenized species-specific nucleotide positions in varanid lineage. Most VSAREP sequences were shared among varanids within the four VSAREP subfamilies. This suggests that nucleotide substitutions in each varanid species accumulated more slowly than homogenization rates in each VSAREP subfamily, resulting in non-species-specific evolution of stDNA profiles. Moreover, changes in location of VSAREP stDNA in each Australian varanid suggests a correlation with chromosomal rearrangements, leading to karyotypic differences among these species. © 2017 The Author(s).},

abstract = {Genomic alteration in head and neck squamous cell carcinoma (HNSCC) was studied in two cell line pairs (HN30-HN31 and HN4-HN12) using conventional C-banding, multiplex fluorescence in situ hybridization (M-FISH), and array comparative genomic hybridization (array CGH). HN30 and HN4 were derived from primary lesions in the pharynx and base of tongue, respectively, and HN31 and HN12 were derived from lymph-node metastatic lesions belonging to the same patients. Gain of chromosome 1, 7, and 11 were shared in almost all cell lines. Hierarchical clustering revealed that HN31 was closely related to HN4, which shared eight chromosome alteration cases. Large C-positive heterochromatins were found in the centromeric region of chromosome 9 in HN31 and HN4, which suggests complex structural amplification of the repetitive sequence. Array CGH revealed amplification of 7p22.3p11.2, 8q11.23q12.1, and 14q32.33 in all cell lines involved with tumorigenesis and inflammation genes. The amplification of 2p21 (SIX3), 11p15.5 (H19), and 11q21q22.3 (MAML2, PGR, TRPC6, and MMP family) regions, and deletion of 9p23 (PTPRD) and 16q23.1 (WWOX) regions were identified in HN31 and HN12. Interestingly, partial loss of PTPRD (9p23) and WWOX (16q23.1) genes was identified in HN31 and HN12, and the level of gene expression tended to be the down-regulation of PTPRD, with no detectable expression of the WWOX gene. This suggests that the scarcity of PTPRD and WWOX genes might have played an important role in progression of HNSCC, and could be considered as a target for cancer therapy or a biomarker in molecular pathology. © 2016 Singchat et al.

abstract = {Centromere protein B (CENP-B) is one of the major proteins involved in centromere formation, binding to centromeric repetitive DNA by recognizing a 17 bp motif called the CENP-B box. Hominids (humans and great apes) carry large numbers of CENP-B boxes in alpha satellite DNA (AS, the major centromeric repetitive DNA of simian primates). Only negative results have been reported regarding the presence of the CENP-B box in other primate taxa. Consequently, it is widely believed that the CENP-B box is confined, within primates, to the hominids. We report here that the common marmoset, a New World monkey, contains an abundance of CENP-B boxes in its AS. First, in a long contig sequence we constructed and analysed, we identified the motif in 17 of the 38 alpha satellite repeat units. We then sequenced terminal regions of additional clones and found the motif in many of them. Immunostaining of marmoset cells demonstrated that CENP-B binds to DNA in the centromeric regions of chromosomes. Therefore, functional CENP-B boxes are not confined to hominids. Our results indicate that the efficiency of identification of the CENP-B box may depend largely on the sequencing methods used, and that the CENP-B box in centromeric repetitive DNA may be more common than researchers previously thought. © 2016 The Author(s) Published by the Royal Society.
