Riboviruses are involved in some of the most prevalent human diseases, responsible for causing epidemics and pandemics. These viruses have an animal origin and have been known to cross the inter-species barrier time and time again, eventually infecting human beings. Their evolution has been a long road to harbour important adaptations for increasing fitness, mutability and virulence; a result of natural selection and mutation pressure, making these viruses highly infectious and difficult to counter. Accumulating favourable mutations in the course, they imitate the GC content and codon usage patterns of the host for maximising the chances of infection. A myriad of viral and host factors determine the fate of specific viral infections, which may include virus protein and host receptor compatibility, host restriction factors and others. Thus, understanding the biology, transmission and molecular mechanisms of Riboviruses is essential for the development of effective antiviral treatments, vaccine development and strategies to prevent and control viral infections. Keeping these aspects in mind, this review aims to provide a holistic approach towards understanding Riboviruses.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"11-37"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142909758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the viral replication mechanism, both LTRs are identical at the moment of integration, when the provirus becomes part of the host genome. After that time, proviral sequences evolve within the host DNA. When the mutation rate is known, nucleotide divergence between the LTRs would then be a measure of time elapsed since integration. Though frequently used, the approach has been complicated by the choice of host mutation rate and, to a lesser extent, by the method selected to estimate nucleotide divergence. As a result, outcomes can be incompatible with, for instance, speciation events identified from the fossil record. The review will give an overview of research reporting LTR-retroposon dating, and a summary of important factors to consider, including the quality, assembly, and alignment of sequences, the mutation rate of foreign DNA in host genomes, and the choice of a distance estimation method.

While plastome structure is generally conserved, some angiosperm lineages exhibit structural changes. Such is the case of the megadiverse order Asterales, where rearrangements in plastome structure have been documented. This study investigates the possibility of recovering plastid loci from off-target reads obtained through hybrid enrichment techniques. Our sampling includes 63 species from the eleven currently recognized families in Asterales derived from previously published studies. We assembled and annotated complete and partial plastomes using custom pipelines and estimate phylogenomic relationships. We retrieved plastid information from 60 of the 63 sampled species including a complete plastome from Tithonia tubaeformis (Asteraceae), circular partial (with gaps) plastomes from seven species, and non-circular partial plastomes from other 52 species. We focused on the small single-copy region because it could be recovered for over 29 species. Within the small single-copy region, we assessed intron losses and presence of putative pseudogenes. Comparative genomics revealed a relocated fragment of ~ 6500 bp in two Campanulaceae lineages (i. e. subfamily Lobelioideae and Pseudonemacladus oppositifolium), involving the genes rbcL, atpB, atpE, trnM-CAU, and trnV-UAC. Obtained phylogenetic hypotheses were congruent across the applied methods and consistent with previously published results. Our study demonstrates the feasibility of recovering plastid information, both complete and partial, from off-target hybrid enrichment data and provides insights on the structural plastome changes that have occurred throughout the evolution of the order Asterales.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"111-123"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While alanine and glutamate racemases are widespread in bacteria, serine racemase (SerR) is predominantly found in animals. Recently, homologs of animal SerR were reported in some bacterial genomes, but their evolutionary distribution and functional roles remain poorly understood. In this study, we cloned and expressed 20 SerR homologous genes from 13 bacterial species spanning five phyla and characterized their enzymatic activity. Six homologs exhibited serine dehydratase activity, while the remaining showed racemase activity with serine, aspartate, asparagine, or arginine. Notably, the SerR homologs from Parafannyhessea umbonata (Actinomycetota), Clostridium aceticum, Anaerovirgula multivorans, Alkaliphilus oremlandii (Bacillota), Acetomicrobium mobile, and Thermovirga lienii (Synergistota) demonstrated strong arginine racemase activity, with Km values ranging from 0.167 to 0.885 mM and kcat values ranging from 5.86 to 61.5 s-1 for L-arginine. Phylogenetic analysis revealed that bacterial and eukaryotic SerR homologs share a common ancestral gene, and substrate specificity has independently changed multiple times during evolution. Amino acid sequence alignment and analysis of site-directed mutants revealed that residues at positions 146 to 148 and surrounding regions, located near the substrate-binding site, play a crucial role in substrate specificity and/or catalytic activity. These results highlight the evolutionary processes that drive functional diversification in serine racemase homologs.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"149-162"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11850409/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143006926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This unique trait is driven by a complex chromosomal rearrangement on chromosome 20 at the Fm locus, resulting in the overexpression of the EDN3 (a gene central to melanocyte regulation). In contrast, the inhibition of dermal pigmentation is regulated by the Id locus. Although prior studies using genetic crosses, GWAS, and gene expression analysis have investigated the genetic underpinnings of the Id locus, its precise location and functional details remain elusive. Our study aims to precisely locate the Id locus, identify associated chromosomal rearrangements and candidate genes influencing dermal pigmentation, and examine the ancestral status of the Id locus in BBC breeds. Using public genomic data from BBC and non-BBC breeds, we refined the Id locus to a ~1.6 Mb region that co-localizes with Z amplicon repeat units at the distal end of the q-arm of chromosome Z within a 10.36 Mb inversion in Silkie BBC. Phylogenetic and population structure analyses reveal that the Id locus shares a common ancestry across all BBC breeds, much like the Fm locus. Selection signatures and highly differentiated BBC-specific SNPs within the MTAP gene position it as the prime candidate for the Id locus with CCDC112 and additional genes, suggesting a possible polygenic nature. Our results suggest that the Id locus is shared among BBC breeds and may function as a supergene cluster in shank and dermal pigmentation variation.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"163-180"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143006920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tumor Suppressor Genes (TSGs) defects play a crucial role in tumor development, and recent studies propose their reactivation as a promising way for clinical intervention in breast cancer. Here, we performed detailed evolutionary analyses of 241 breast cancer TSGs across 25 mammalian genomes, revealing 28 genes under strong positive selection. These genes exhibit elevated molecular pressure in codons corresponding to amino acids located in crucial protein domains and motifs. Notably, one positively selected site in the BRCA1 C-terminal domain is known for its role in DNA damage response, suggesting potential interference with DNA repair mechanisms. Moreover, the substitution of some other sites found in important key motifs, namely two codons in BRCA2 (752 and 939) localized within the phosphoinositide-3-OH-kinase-related and playing a crucial role in the DNA repair and the DNA damage checkpoints.

MutS2 homologs have been found in plants and some algae; however, their actual diversity in eukaryotes remains unknown. We found putative MutS2 homologs in various species of photosynthetic eukaryotes and performed a detailed analysis of the revealed amino acid sequences. Three groups of homologs were distinguished depending on their domain composition: MutS2 homologs with full set of specific domains, MutS2-like sequences without endonuclease Smr domain, and MutS2-like homologs lacking Smr and clamp in domain IV, the extreme form of which are proteins with only a complete ATPase domain. We clarified the information about amino acid composition and set of specific motifs in the conserved domains in MutS2 and MutS2-like sequences. The models of the predicted tertiary structure were obtained for each group of homologs. The phylogenetic analysis demonstrated that all eukaryotic sequences split into two large groups. The first group included homologs belonging to species of Archaeplastida and a subset of haptophyte homologs, while the second-sequences of organisms from CASH groups (cryptophytes, alveolates, stramenopiles, haptophytes) and chlorarachniophytes. The cyanobacterial MutS2 clustered together with the first group, and proteins belonging to Deltaproteobacteria (orders Myxococcales and Bradymonadales) showed phylogenetic affinity to the CASH-including group with strong support. The observed tree pattern did not support a clear differentiation of eukaryotes into lineages with red and green algae-derived plastids. The results are discussed in the context of current conceptions of serial endosymbioses and genetic mosaicism in algae with complex plastids.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"815-833"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142372076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
