Мобильные генетические элементы (МГЭ) играют большую роль в изменении структуры генома и экспрессии генов. Все многообразие МГЭ подразделяется на два класса – ретротранспозоны и ДНК-транспозоны. У морских беспозвоночных МГЭ представлены последовательностями обоих классов, и они обнаружены в геномах видов всех основных таксонов этой группы животных. Среди представителей типа кишечнополостные (Cnidaria) в литературе описаны МГЭ у видов Aurelia aurita, Acropora millepora, A. palmata, A. digitifera, Nematostella vectensis. МГЭ среди плоских червей (Platyhelminthes) изучены у двух видов - Stylochus zebra и Bdelloura candida, а среди Кольчатых червей (Annelida) у вида Capitella capitata. Иглокожие (Echinodermata) в работе представлены видами Strongylocentrotus purpuratus, S. franciscanus, S. drobachiensis, Tripneustes gratilla, Lytechinus pictus, L. variegatus, Arbacia punctulata и Eucidaris tribuloides. Представленность МГЭ у моллюсков (Mollusca) изучена на примерах видов Mytilus galloprovincialis, Chione cancellata, Crassostrea gigas, C. virginica, Anadara trapezia, Aplysia californica, Gibbula cineraria, Littorina littorea и L. saxatilis. Наиболее изучено распространение МГЭ у типа Членистоногие (Arthropoda), этот таксон представлен работами по видам Bythograea thermydron, Ventiella sulfuris, Maia brachydactila, Cancer pagurus, Pachygrapsus marmoratus, Penaeus monodon, P. vannamei, Litopenaeus stylirostris, Agononida laurentae, Galathea squamifera, Munida acantha, M. thoe, M. gregaria, M. zebra и Munidopsis recta, Eumunida annulosa, E. sternomaculata и Rimicaris exoculata. Часть хордовых (Chordata), не относящихся к подтипу Vertebrata, была исследована на предмет содержания МГЭ; изучались геномы видов Ciona intestinalis, Oikopleura dioica и Branchiostoma floridae. Рассмотрено разнообразие МГЭ, их свойства и роль в преобразовании структуры и изменении функции генов и геномов, в онтогенезе и в эволюции.

Mobile genetic elements (MGE) play an important role in genome structure and gene expression changes. All types of MGE are subdivided to two classes – retrotransposons and DNA-transposons. MGE were found in genomes of all main taxa of marine invertebrates and are represented by both classes. MGEs were found in genomes of Cnidaria species: Aurelia aurita, Acropora millepora, A. palmata, A. digitifera, Nematostella vectensis. MGE were studied in two flatworms (Platyhelminthes) species - Stylochus zebra and Bdelloura candida. In Annelida taxa, MGE were studied for Capitella capitata species. Echinodermata were represented in the review study by species Strongylocentrotus purpuratus, S. franciscanus, S. drobachiensis, Tripneustes gratilla, Lytechinus pictus, L. variegatus, Arbacia punctulata, and Eucidaris tribuloides. A quantity of MGE in Mollusca was studied for following species: Mytilus galloprovincialis, Chione cancellata, Crassostrea gigas, C. virginica, Anadara trapezia, Aplysia californica, Gibbula cineraria, Littorina littorea, and L. saxatilis. The type of Arthropoda is the most studied for MGE presence. MGE presence was studied for following Arthropoda species: Bythograea thermydron, Ventiella sulfuris, Maia brachydactila, Cancer pagurus, Pachygrapsus marmoratus, Penaeus monodon, P. vannamei, Litopenaeus stylirostris, Agononida laurentae, Galathea squamifera, Munida acantha, M. thoe, M. gregaria, M. zebra, Munidopsis recta, Eumunida annulosa, E. sternomaculata, and Rimicaris exoculata. A part of Chordata taxon, which is not included in Vertebrata subtupe, was studied too. This part was represented in the review by species Ciona intestinalis, Oikopleura dioica, and Branchiostoma floridae. A diversity of MGEs and their characters and its role in ontogenesis, in evolution and in changes of functions of genes and genomes were discussed.
