The widespread implementation of primerless sequencing methods in routine laboratory practice has streamlined the development of marine virology from initial observations of virus-like particles in seawater, once deemed exotic, to comprehensive generalizations that reshape our understanding of global problems in the World Ocean. These include the continuous depletion of biological resources and diversity, marine pollution, and global climate change. Nevertheless, in terms of virology, the World Ocean remains a true <i>aqua incognita</i>, and marine virology, as a subset of general virology, and marine biology are just at the initial stages of their development, standing on the threshold of new discoveries. Those discoveries have the potential to reveal fundamental processes in the origin and evolution of life on Earth, to accelerate the development of novel technologies, and even foster innovative approaches to reshaping the noosphere. The aim of this review is to draw scientific attention to the numerous problematic aspects of viruses in the World Ocean.

The analysis of the expression of regulatory genes (along with the data of classical comparative anatomy) allows us to prove the homology of the pharyngeal plane of Anthozoa and the sagittal plane of triploblatic Bilateria and to confirm the origin of the coelomic segments from the peripheral gastric pockets of coelenterone. At the same time, an end-to-end homology of the segments is assumed within the Bilateria. The homology of the preoral segment and the tentacular segment in all Bilateria is emphasized. It is assumed that the ancestors of Bilateria had two circles of tentacles, labial and marginal. The marginal tentacles of the coelenterates are homologous to the metameric appendages of Bilateria, and the labial tentacles are homologous to the perioral ciliated tentacles and the ventral ciliated sole. The ciliary bands of larvae are homologous to the labial ciliated tentacles transferred to the larval stage. Possible homologues of metameric appendages and ciliated tentacles in Deuterostomia are discussed. In chordates (taking into account the “upside-down theory” of their origin), the radials of the median fin are considered as homologues of the labial tentacles, while the radials of paired fins are considered as homologues of the marginal tentacles. Two-phase expression of <i>Hox</i> genes allows us to prove the homology of tetrapod digits and fin radials of primitive fish. The similarity of the genetic mechanisms regulating the development of limbs makes it possible to stretch the threads of homology from the coelenterate tentacles to the limbs of vertebrates.</p>","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140881630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flagellum is strengthened by two circles of microtubules in addition to the central axoneme. Oogenesis is intraovarian. Developed oocytes are about 130 µm in diameter, with an envelope about 0.8 µm thick, consisting of three layers of extracellular matrix: the thickest basal layer penetrated by unbranched microvilli each about 0.4 µm long, a homogenous intermediate layer with the highest electron density, and the outer brush-like layer with numerous extensions each about 0.3 µm long.

Of the three larval characters studied—length of body rod, length of post-oral arms, and length of body midline—the length of post-oral arms was found to be the most variable in terms of mean and variance values. The relative difference in the post-oral arm length varied from 0.002 to 9.3% between the technical replicates within a cross and considerably differed in 5 out of 20 biological replicates. In contrast, the relative difference in the mean body rod length between the technical replicates ranged within 0.06–4.7%, and the relative difference in the mean body midline length was within 0.12–10.22%. Only one biological replicate showed a statistically significant difference in the mean body midline length between the technical replicates, and none of biological replicates had statistically significant differences in the mean body rod length between their technical replicates. Our results have shown that the degree of variability differs among larval characters. These observations can help estimate the degree of variability in certain characters of sea urchin larvae to be taken into account when planning, analyzing, and interpreting results of experimental studies.
