Summary: Leuciscus merzbacheri is a unique cyprinid fish species in China, mainly found in Xinjiang Province. It plays a significant role in studying the adaptability and evolution of salt and alkali tolerance in the Junggar Basin. Through high-throughput sequencing, the complete mitochondrial sequence of L. merzbacheri was obtained for the first time, revealing a circular mitogenome with a length of 16,609 bp and containing 37 genes, including protein-coding, transfer RNA, and ribosomal RNA genes. Phylogenetically, L. merzbacheri appears to have an early origin as it is located on a new branch near the base of the phylogenetic tree.

Summary: Gyrodactylus, a diverse genus with approximately 500 species worldwide, has 33 species recorded in Mexico. In the last two decades, 26 new species, including Gyrodactylus ticuchi n. sp. and Gyrodactylus tobala n. sp., have been described from freshwater fish in Mexico. These new species from cyprinids in southern Mexico exhibit slight morphological and molecular differences from their congeners.

Summary: The study identified 140 homoeologous recombinations between two triploids and detected transcriptions of homoeologous recombinant genes. By comparing expressed recombinant reads to total expressed reads, the potential relationship between homoeologous recombinations related to innate immunity and adaptation of the triploids and allotetraploids was revealed.

Summary: This study evaluated the effects of magnesium ion on the banding pattern and ultrastructure of chromosomes. The results showed that magnesium ion can condense the chromosome structure and result in a clear banding pattern, while the absence of magnesium ion and treatment with a cations-chelator led to an expanded chromosome structure with a lower intensity of the banding pattern.

Summary: Efficiently maintained artificial chromosome TtAC2 was successfully designed mimicking the native macronuclear rDNA minichromosome for expressing recombinant proteins in Tetrahymena thermophila. The TtAC2 showed stable maintenance and functionality for protein expression in the ciliate, providing a novel vector option for recombinant biology and biotechnology applications.

Summary: This study investigates the potential of single-molecule optical genome mapping (OGM) in detecting cryptic chromosomal rearrangements. OGM successfully detected cryptic reciprocal translocations in 11 couples, and the results were consistent with other experimental methods. The study suggests that OGM is a rapid and accurate method for detecting cryptic BCRs, and it provides additional genetic information.

Summary: This study presents the first cytogenetic data of two allopatric populations of Moenkhausia bonita and one of M. forestii, revealing differences in chromosome number, karyotype formula, and B chromosomes between the two species. These distinctions may contribute as a reference in taxonomic studies of this genus, providing insights into the evolutionary and cytotaxonomic aspects.

Summary: The study conducted a cytogenetic analysis on five out of the seven species of the genus Lyciasalamandra, revealing a high diversity in karyotype configuration and nucleolus organizing regions (NORs). The unique taxon-specific NOR configuration supports the taxonomic validity of different evolutionary lineages and suggests a scenario of synchronous evolution in the Lycian salamanders. The observed variability in NORs is likely derived from multiple independent translocations and inversions, contributing to lineage divergence in Lyciasalamandra.

Summary: This study conducted a comparative analysis of the genome organization and chromosome structure of the important species Salvia officinalis and Salvia sclarea. The results revealed interspecific variations in repetitive DNA and identified potential chromosome markers. This research provides valuable insights into the taxonomy and genetic diversity of these two Salvia species.

Summary: Festuca and Lolium grass species show trait complementarities in hybrid variety production, but they also exhibit antagonisms and rearrangements at the genome level. A rare case of an unstable hybrid was discovered, with the donor plant showing pronounced variability in its clonal parts. The study identified diploid plants with a reduced chromosome number derived from F. pratensis, which plays a significant role in recombinant chromosomes. The finding highlights the plasticity of plant genomes and the ability of F. pratensis to restructure itself from a chaotic chromosomal cocktail.

Summary: The mitotic spindle is a macromolecular machine responsible for faithful chromosome segregation during cell division. Assembly of the spindle is guided by the 'Search & Capture' principle in structured space. Nucleation of noncentrosomal microtubules near kinetochores and changes in kinetochore architecture promote rapid and accurate assembly of the spindle.

Summary: The order Gobiiformes consists of over 2200 species and is considered one of the most diverse groups among teleost fishes. This study expanded cytogenetic data for four neotropical species in the Eleotridae family and used a meta-analytical approach to explore the karyotype diversification in relation to biological aspects.

Summary: This study assessed the ovary structure and early oogenesis in representatives of Osteoglossomorpha, comparing internally fertilizing Pantodon buchholzi with externally fertilizing species, revealing differences in ovary structure and oocyte organization between them. These differences may be attributed to long separate evolution of the families and adaptation to insemination in Pantodontidae.

Summary: The genome sizes of eukaryotic organisms vary due to whole-genome duplications and transposable element expansion. This study found that the genome expansion in European and North American mudminnows is mainly driven by the expansion of DNA transposon and unclassified repeat sequences. The ongoing expansion of repeat sequences in the Alaska blackfish Dallia pectoralis suggests a similar genome expansion may be occurring in this species as well.

Summary: This study quantified and compared the changes in concentrations of 17β-estradiol (E2), testosterone (T), and 11-ketotestosterone (11-KT) in the gonads and plasma of diploid and triploid gibel carp. It was found that the concentrations of these hormones mainly depended on the reproductive phase rather than ploidy. Gibel carp, regardless of ploidy, had an extended period of reproduction, and the differences in sex hormone concentrations between 2n and 3n females may contribute to the coexistence of gynogenetic C. gibelio females and sexual diploids.
