Summary: The sex-determining region in Nile tilapia has been found on linkage groups 1, 20, and 23. Previous studies have only focused on wild populations from Ghana and Ethiopia. In a wild population from Lake Hora, Ethiopia, no sex-determining region on linkage group 23 was found, and there was no duplication of the amh gene. The genetic basis of sex determination in this population remains unknown.

Summary: Oxidative damage-induced mitochondrial dysfunction may lead to muscle weakening in idiopathic inflammatory myopathies. This study found that single nucleotide polymorphisms (SNPs) in the mitochondrial displacement loop (D-loop) were associated with mitochondrial DNA (mtDNA) copy number and the risk of polymyositis and dermatomyositis. The mtDNA of patients with polymyositis and dermatomyositis showed D-loop SNP accumulation compared to controls. Additionally, certain SNPs were more common in patients with polymyositis and dermatomyositis. Further analysis revealed that these SNPs were associated with cytokine expression and the presence of certain antibodies in patients.

Summary: This study provides a comprehensive assessment of the genetic diversity of Chinese giant pandas based on 13 mitochondrial protein coding genes. The researchers obtained long sequences for 110 giant panda individuals and discovered three new haplotypes, which contributes to a better understanding of the genetic variation between captive and wild giant panda populations.

Summary: Mitochondrial DNA (mtDNA) is essential for respiratory metabolism and can exist in a state of heteroplasmy. This study investigates the resolution of mtDNA heteroplasmy in yeast hybrids and finds that hybridization induces mtDNA degeneration, leading to consequences for mtDNA evolution, metabolism, and reproductive isolation.

Summary: In this study, a NAC25-like transcription factor was isolated and characterized from different coffee species. The gene structure, variation, and expression of the NAC25 gene were analyzed. The study demonstrated differential expression of NAC25 in different tissues and revealed the independent evolution of NAC25 in coffee.

Summary: A novel cardiovirus, HHMCDV, was identified in fecal samples from wild Himalayan marmots in the Qinghai Tibetan Plateau. The virus showed a closer relationship with the Cardiovirus F strain and may represent a potential new species within the genus Cardiovirus.

Summary: This study used the mitochondrial barcoding region to investigate the origin, phylogenetic relationships, and biogeographic history of mites in the Laelapidae family. Phylogenetic trees were constructed using Bayesian inference and Maximum-likelihood methods, and divergence times and biogeographic history were estimated. The results showed a close relationship between species in the genera Hyperlaelaps, Haemolaelaps, and Androlaelaps with the genus Laelaps. The family Laelapidae likely diverged from other taxa during the Middle Jurassic, and Asia was the most likely ancestral region. The study provides insights into the origin and evolution of species in the Laelapidae family.

Summary: The aim of this study was to investigate the genetic diversity and structure of Trifolium fragiferum populations in Latvia and the Baltic Sea region. The wild populations showed lower genetic diversity compared to the cultivar 'Palestine'. The populations in Latvia were differentiated into clusters, with the populations near Riga being genetically distinct from each other. The results can be used for further studies and conservation strategies for this crop wild relative species in the Baltic Sea region.

Summary: Skin pH plays a role in disease susceptibility, with variations seen among different bat species, geographic locations, sexes, age classes, and seasons. The pH of bat skin may impact susceptibility to white-nose syndrome, with skin acidity potentially affecting resistance to the fungal infection. Future research on skin pH and its influence on microbial pathogenic factors may provide insights into therapeutic targets for treating bat skin conditions.

Summary: Cyathostomins, important intestinal nematode parasites of equines, include 50 accepted species. This study found no obvious differentiation between geographic regions or equine host species, and a combined analysis of nuclear and mitochondrial haplotypes improved resolution of the phylogeny. This approach should be applied to remaining cyathostomin species across different equine host species and geographic regions.

Summary: Contrary to early evidence, recent studies found that some species exhibit elevated rates of mitochondrial architecture evolution. Two congeneric shell-boring Spionidae species sequenced in this study showed very similar mitochondrial architecture with unique features, including completely rearranged gene orders. These species, along with two other sedentarian lineages, exhibited disproportionately elevated rates of mitogenomic architecture rearrangements and relaxed purifying selection pressures.

Summary: This study investigated the morphological traits and genetic diversity of wild hops in the Calabria region of South Italy. Cone length showed significant variation among different populations, while cone shape was the most discriminant trait. Genetic diversity analysis using eight SSR markers revealed high genetic variability in Calabria, and genetic structure analysis identified two distinct groups regardless of the sampling sites. Further research will be conducted to explore other wild hops populations in Calabria and identify specific alleles for new breeding programs.

Summary: This study compared the gut ecological information of captive and wild long-tailed gorals and found that captive gorals had lower gut ecological diversity. It suggested using gut eco-information as an evaluation index before reintroducing captive gorals and identified additional food sources from the gut eco-information of wild gorals to enhance the intestinal ecological diversity of captive animals.

Summary: In this study, we generated a high-quality mitochondrial genome assembly for Oryza granulata using a hybrid approach integrating Illumina and PacBio sequencing data. The analysis revealed the unique characteristics and structural variation of the O. granulata genome. The phylogenetic analysis showed the close genetic relationship of O. granulata with other Oryza species, providing insights for conservation and utilization of wild rice biodiversity.
