Summary: Using genome assemblies of damselfly and dragonfly species, the study found that the autosomes of Odonata have maintained chromosomal orthology despite millions of years of separation. Various factors, such as repeat dynamics, GC content, and chromosome position, influence the density of syntenic blocks across chromosomes, but there is no consistent pattern between species. Additionally, the micro-chromosomes in Odonata are descended from a common ancestor, and, in one species, the micro-chromosome was lost through fusion with autosomes.

Summary: Chromosome rearrangements in aphids have led to a significant reorganization over the past 30 million years, resulting in the inability to determine chromosome homology between Aphidini and Macrosiphini tribes. Despite rapid sequence evolution, low gene expression, and high transposable element load, gene content of the aphid sex (X) chromosome remained unchanged. Blood-feeding hemipterans, despite being more diverged, have conserved synteny, suggesting that rapid evolution of genome structure may be a unique characteristic of aphids.

Summary: In this study, the haplotype-resolved genome of D. caryophyllus 'Aili' was assembled for the first time at the chromosome level. The lengths of the two assembled haplotypes were determined, and structural variations between the haplotypes were identified. Phylogenetic analysis revealed the species differentiation time between carnation and gypsophila to be approximately 54.43 million years ago. This assembled and annotated genome will facilitate molecular biology studies and contribute to genome-level evolutionary research.

Summary: The study identified five chloroplast genomes of Oedogonium species, revealing their structural conservation but variation in genome sizes, AT contents, introns, and repeats. Phylogenetic analyses suggested that both Oedocladium and Oedogonium are polyphyletic groups. The identification of a positively selected gene in certain species indicates adaptive evolution in terrestrial Oedogoniales taxa.

Summary: The genome of the rice leaffolder was sequenced and assembled successfully, providing a high-quality resource for further research in insect migration, chromosome evolution, and pest control. The genome assembly revealed insights into repeat sequences, expanded gene families associated with hormone biosynthesis, and high chromosomal synteny with other lepidopteran insects. Specifically, the identification of a near-intact W chromosome with enriched metabolic pathways is a significant finding with potential implications for understanding the species.

Summary: Unlike birds and mammals, many teleosts have homomorphic sex chromosomes, and turnovers are common in these chromosomes. This study focused on two seahorse species to investigate the evolution of new sex-determining regions and the accumulation of evolutionary changes in newly sex-linked regions. The analysis revealed that both seahorse species have XY sex chromosome systems with non-homologous sex chromosome pairs, suggesting a turnover event. The Y-linked regions were found to occupy a significant proportion of the sex chromosome and exhibited occasional recombination, indicating that they did not evolve through recombination suppression.

Summary: Examining the changes in order and arrangement of homologous genes is crucial for understanding genome evolution in eukaryotes. This study analyzed 120 high quality genomes of budding yeast species to investigate the evolution of genome organization and compared it with animals and plants. The decay of macrosynteny and microsynteny was strongly associated with evolutionary divergence in the budding yeast major clades. However, the microsynteny of many genes, especially in metabolic clusters, was deeply conserved within major clades and across subphylum. Comparing genomes with similar divergence times, budding yeasts showed lower conservation in macrosynteny compared to animals and filamentous fungi, but higher conservation than angiosperms. In contrast, they exhibited similar levels of microsynteny conservation with mammals, while angiosperms had very low conservation.

Summary: This study investigates the evolution of a giant sex chromosome in cichlid fish, finding that it consists of three distinct regions and contains unprecedented amounts of endogenous retroviral elements, immunoglobulin genes, and long non-coding RNAs. Comparative analysis across 69 teleost genomes supports the hypothesis that the giant sex chromosome originated from the fusion of a B chromosome.

Summary: This study obtained high-quality genomes of two strains of Folsomia candida and conducted comparative genomic analyses. The results showed differences in genome structure, chromosome size, and gene numbers between the parthenogenetic and sexual strains. The high similarity between genomes of the parthenogenetic strains suggested that they are conspecific. Strain-specific genes and gene families were found to be related to environmental adaptation.

Summary: Rosa rugosa, an important shrub with economic, ecological, and pharmaceutical value, had its genome sequenced using PacBio and Hi-C technologies. The assembled genome had a size of 407.1 Mb, with 98% of the sequences anchored to seven pseudochromosomes. Phylogenetic and synteny analysis revealed the evolutionary history and gene conservation between R. rugosa and other closely related species. The genome provides valuable resources for molecular-assisted breeding and horticultural genomics research.

Summary: In this study, cytogenetic and molecular FISH techniques were used to investigate the chromosome morphology and rearrangements in an allotetraploid species of the sister subgenus Silurana. The results showed that the subgenomes of this species have distinctive characteristics, with one subgenome being more conserved and resembling a closely related diploid species, while the other subgenome evolves more rapidly and exhibits pronounced changes in chromosome structure.

Summary: Using fluorescence in situ hybridization and genomic data, we mapped repetitive elements in six species of African clawed frogs and found that polyploidization and divergence play important roles in the evolution of repetitive elements. We also observed conserved loci number and position in one of the subgenus species, while the number of signals varied in other species derived from different polyploidization events.

Summary: Desmin mutations cause cardiomyopathies and negatively impact mitochondria. The deficiency of desmin results in impaired oxidative phosphorylation and fatty and amino acid metabolism in cardiac mitochondria. Increased glucose utilization and upregulation of fetal creatine kinase are compensatory mechanisms to maintain myocardial energy supply.

Summary: Sertoli cells (SCs) have been shown to undergo osteogenic, chondrogenic, and adipogenic differentiation successfully, with anti-inflammatory and protective effects. Compared to MSCs, SCs more effectively induce M2 macrophage polarization and regulate inflammatory polarization. Additionally, SCs have demonstrated the ability to transfer mitochondria to immune cells.

Summary: In some vertebrate groups like fishes, amphibians, and lizards, interruptions in sex chromosome differentiation are believed to be caused by frequent sex chromosome turnover and occasional recombination between sex chromosomes. The Amazonian frogs of the genus Engystomops have shown evidence of the loss of sex chromosome heteromorphism, with highly divergent karyotypes and unique X and Y chromosome evolution. The phylogenetic data suggest that sex chromosome heteromorphism may have appeared early in the evolution of Engystomops species in the Amazon, but has been lost in some unnamed candidate species.
