Summary: This study characterized the population genetic structure of the purplish bifurcate mussel in the northwestern Pacific, identifying two mitochondrial lineages (southern and northern) that may have diverged due to historical sea level fluctuations and adaptation to different temperature zones. Discordance between mitochondrial and nuclear markers suggests potential cryptic speciation and the need for further genomic analyses to explore this divergence.

Summary: In this study, the mitochondrial genome of Mytilisepta virgata was analyzed. The gene arrangement was found to be relatively conserved at the genus level, but exhibited a high level of rearrangement compared to the putative molluscan ancestral gene order. Phylogenetic analysis based on concatenated 12 PCGs from Mytilidae placed M. virgata in the same clade as other Mytilisepta spp. Divergence time estimation indicated that M. virgata and M. keenae diverged in the early Paleogene period.

Summary: This study reveals that the contact zone between two direct repeats on mitochondrial DNA is a hot spot for deletions, which may be associated with human aging. The direct repeats within the contact zone are more likely to cause mutations compared to repeats outside the zone. These findings have important implications for predicting mutation burden and maximum lifespan in human populations and mammalian species.

Summary: There is an additional set of sex-specific mtDNA-encoded proteins in bivalve species with doubly uniparental mitochondrial inheritance that may be involved in the transmission of the female and male mito-genomes. In Mytilus edulis, the translation of the female-specific open reading frame (F-ORF) has been demonstrated, but the translation of the male-specific ORF (M-ORF) is still to be shown. This study validates the M-ORF of the paternal mitogenome in M. edulis as a protein-coding gene. The M-ORF protein is only detected in male gonads and is localized in sperm mitochondria and acrosome, suggesting its involvement in a key sperm function in Mytilus edulis.

Summary: The morphological structure of the byssal apparatus, byssal threads, and pedal groove in the commercial Pacific mussel species, Mytilus trossulus, from the Sea of Japan, have been studied. The process of byssal threads formation and the morphological features of the byssal groove related to this process are described. The spatial distribution of mytilids in marine coastal zones is discussed with a focus on rocky shores with active wave activities being a successful habitat for M. trossulus.

Summary: Despite concerns over population reduction, Mytilus coruscus populations in Korean coasts exhibit high genetic diversity. A distinct genetic pattern was observed in Korean populations compared to Chinese wild populations, with shared haplotypes between the two.

Summary: Morphological features of the byssal groove of the foot were studied in three common mytilid species from the Sea of Japan. Interspecies differences in the length, width, and depth of the groove, as well as the structure of the attachment area, were found. These differences can be explained by variations in the secretory organ.

Summary: To study the genetic characteristics of Mytilus unguiculatus populations in the coast of China, mitochondrial DNA was analyzed. The study discovered high genetic diversity and weak genetic structure among seven populations. There were no significant population differentiation or demographic events observed. The results suggest that these populations belong to the same group.

Summary: The study identified two lineages of bivalve transmissible neoplasia (BTN), BTN1 and BTN2, in blue mussels Mytilus, with BTN2 being reported for the first time in its original host species M. trossulus in the Sea of Japan. The presence of BTN2 in M. trossulus suggests a common origin of BTN2 diversity in populations of M. trossulus outside the Northeast Pacific, possibly in the Northwest Pacific.

Summary: Research on the Pharidae family is limited, but sequencing the complete mitochondrial genome of S. minima revealed great variability in gene sequences among bivalve species, with higher consistency in gene arrangement among species that are genetically closer. Gene rearrangement is particularly obvious among families, while gene order within families is relatively conservative. The S. minima mitogenome provided will enhance the phylogenetic resolution of Pharidae species.

Summary: The Krebs cycle enzyme fumarase is involved in DNA damage response by protecting the desulfurase Nfs1p in mitochondria from modification and inactivation. Overexpression of Nfs1p can enhance DNA repair enzyme activity and compensate for the lack of fumarase.

Summary: The impairment of the airway epithelium barrier function is a common histological feature in asthmatic patients. This study investigated the mechanism by which proteolytic allergens disrupt the epithelial barrier integrity. The findings suggest that Aspergillus oryzae protease induces mitochondrial reactive oxygen species (ROS), leading to mitochondrial dysfunction and subsequent impairment of cellular barrier integrity.

Summary: Mitochondria play a crucial role in the aging process, with degradation of their function leading to increased oxidative stress and ultimately promoting aging. Research has shown differences in flux control of the electron transfer system between long-lived and short-lived species, with long-lived species exhibiting stronger control by complex IV in respiration.

Summary: Studies have found additional putative sperm transmission element (STE) signatures in the large unassigned regions of various marine clams and freshwater mussels with doubly uniparental inheritance (DUI), indicating potential implications for understanding the origin of DUI in ancestral bivalve mollusks and suggesting future in vitro and in silico studies to further refine our understanding of this unusual mtDNA inheritance system.

Summary: The mitochondrial oxidative stress theory of aging suggests that the decline in mitochondria contributes to aging through increased oxidative stress. Using marine bivalves as an aging model, we found that regardless of lifespan, the bivalve ETS is arrayed as a set of supercomplexes with varying degrees of organization.

Summary: The study found that cold-acclimated chickadees had increased mitochondrial respiratory capacity in their pectoralis muscle and liver, correlating with thermogenic capacity and basal metabolic rate. Mitochondrial density markers also showed an increase. The mitochondrial metabolism in the muscle and liver of cold-acclimated birds was associated with thermoregulation and basal maintenance costs.
