These characteristics have shaped spatial patterns of biodiversity between and within species of reef and shore fishes of the region, which has a very high rate of endemism. Scorpaenodes xyris, a small ecologically cryptic reef-dwelling scorpionfish, is widely distributed throughout the TEP, including all the mainland reef areas and all the oceanic islands. This wide distribution and its ecological characteristics make this species a good model to study the evolutionary history of this type of reef fish across the breadth of a tropical biogeographical region. Our evaluation of geographic patterns of genetic (mitochondrial and nuclear) variation shows that S. xyris comprises two highly differentiated clades (A and B), one of which contains four independent evolutionary subunits. Clade A includes four sub-clades: 1. The Cortez mainland Province; 2. The Revillagigedo Islands; 3. Clipperton Atoll; and 4. The Galapagos Islands. Clade B, in contrast, comprises a single unit that includes the Mexican and Panamic mainland provinces, plus Cocos Island. This geographical arrangement largely corresponds to previously indicated regionalization of the TEP. Oceanic distances isolating the islands have produced much of that evolutionary pattern, although oceanographic processes likely have also contributed.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"842-860"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142644289","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}

In this paper, a biothermodynamic analysis was made of hemoglobin and red blood cells. Molecular formulas, empirical formulas, biosynthesis reactions, and thermodynamic properties of formation and biosynthesis were determined for the alpha chain, beta chain, heme B, hemoglobin and red blood cells. Empirical formulas and thermodynamic properties of hemoglobin were compared to those of other biological macromolecules, which include proteins and nucleic acids. Moreover, the energetic requirements of biosynthesis of hemoglobin and red blood cells were analyzed. Based on this, a discussion was made of the specific structure of red blood cells (i.e. no nuclei nor organelles) and its role as an evolutionary adaptation for more energetically efficient biosynthesis needed for the turnover of red blood cells.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"776-798"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142622144","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}

To address this challenge, the present study investigated the molecular interactions of 6 viral proteins (Rep, TrAP, C4, C5, V2, and βC1) with 18 cotton Transcriptional Gene Silencing (TGS) proteins. Protein-protein dockings conducted for different viral-host protein pairs using Clustered Protein Docking (ClusPro) and Global RAnge Molecular Matching (GRAMM) (216 docking runs), revealed variable binding energies. The interacting pairs with the highest binding affinities were further scrutinized using bioCOmplexes COntact MAPS (COCOMAPS) server, which revealed robust binding of three viral proteins- TrAP, C4, and C5 with 14 TGS proteins, identifying several novel interactions (not reported yet by earlier studies), such as TrAP targeting DCL3, HDA6, and SUVH6; C4 targeting RAV2, CMT2, and DMT1; and C5 targeting CLSY1, RDR1, RDR2, AGO4, SAMS, and SAHH. Visualizing these interactions in PyMol provided a detailed insight into interacting regions. Further assessment of the impact of 18 variants of the C4 protein on interaction with CMT2 revealed no correlation between sequence variation and docking energies. However, conserved residues in the C4 binding regions emerged as potential targets for disrupting viral integrity. Hence, this study provides valuable insights into the viral-host interplay, advancing our understanding of Cotton leaf curl Multan virus pathogenicity and opening novel avenues for devising various antiviral strategies by targeting the host-viral interacting regions after experimental validation.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"891-911"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142622146","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}

Leveraging functional and high-throughput assays, along with computational data mining, has led to a remarkable expansion of our understanding of multifunctional protein (and gene) families over the past few decades. Various molecular and intermolecular mechanisms are now known that collectively meet the cumulative multifunctional demands in higher organisms along an evolutionary path. This multitasking ability is attributed to a certain degree of intrinsic or adapted flexibility at the structure-function level. Evolutionary diversification of structure-function relationships in proteins highlights the functional importance of intrinsically disordered proteins/regions (IDPs/IDRs) which are highly dynamic biological soft matter. Multifunctionality is favorably supported by the fluid-like shapes of IDPs/IDRs, enabling them to undergo disorder-to-order transitions upon binding to different molecular partners. Other new malleable members of the protein superfamily, such as those involved in fold-switching, also undergo structural transitions. This new insight diverges from all traditional notions of functional singularity in enzyme classes and emphasizes a far more complex, multi-layered diversification of protein functionality. However, a thorough review in this line, focusing on flexibility and function-driven structural transitions related to evolved multifunctionality in proteins, is currently missing. This review attempts to address this gap while broadening the scope of multifunctionality beyond single protein sequences. It argues that protein intrinsic disorder is likely the most striking mechanism for expressing multifunctionality in proteins. A phenomenological analogy has also been drawn to illustrate the increasingly complex nature of modern digital life, driven by the need for multitasking, particularly involving media.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"669-684"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142108231","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}

We have previously shown that SEM, with rates consistent with experimental observation, can both increase the rate of gene fixation and decrease pseudogenization, thus dramatically improving the efficacy of evolution. Here, we present a conjectural model of the origin and evolution of sex determination wherein the SEM mechanism alone is sufficient to parsimoniously trigger and guide the evolution of heteromorphic sex chromosomes from the initial homomorphic chromosome configuration, without presupposing any allele frequency differences. Under this theoretical model, the SEM mechanism (i) predated vertebrate sex determination origins and evolution, (ii) has been conveniently and parsimoniously co-opted by the vertebrate sex determination systems during the evolutionary transitioning to the extant vertebrate sex determination, likely acting \"on top\" of these systems, and (iii) continues existing, alongside all known vertebrate sex determination systems, as a universal pan-vertebrate sex determination modulation mechanism.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"861-873"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11646274/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675959","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}

Relatively little is known about the role of smell in the evolution of mysticetes (baleen whales). While their toothed cousins, the odontocetes, lack the anatomical features to smell, it is less clear whether baleen whales have retained this sense, and if so, when the pressure on olfaction diverged in the cetacean evolutionary lineage. We examined eight genes encoding olfactory signal transduction pathway components and key chaperones for signs of inactivating mutations and selective pressures. All of the genes we examined were intact in all eight mysticete genomes examined, despite inactivating mutations in odontocete homologs in multiple genes. We also tested several models representing various hypotheses regarding the evolutionary history of olfaction in cetaceans. Our results support a model where olfactory ability is specifically reduced in the odontocete lineage following their split from stem cetaceans and serve to clarify the evolutionary history of olfaction in cetaceans.","PeriodicalId":16366,"journal":{"name":"Journal of Molecular Evolution","volume":" ","pages":"912-929"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142710451","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}
