Santagata S Journal of experimental zoology. Part B, Molecular and developmental evolutionJ Exp Zool B Mol Dev EvolGenes with evidence of positive selection as potentially related to coloniality and the evolution of morphological features among the lophophorates and entoprocts.267-28010.1002/jez.b.22975Evolutionary mechanisms that underlie the origins of coloniality among organisms are diverse. Some animal colonies may be comprised strictly of clonal individuals formed from asexual budding or comprised of a chimera of clonal and sexually produced individuals that fuse secondarily. This investigation focuses on select members of the lophophorates and entoprocts whose evolutionary relationships remain enigmatic even in the age of genomics. Using transcriptomic data sets, two coloniality-based hypotheses are tested in a phylogenetic context to find candidate genes showing evidence of positive selection and potentially convergent molecular signatures among solitary species and taxa-forming colonies from aggregate groups or clonal budding. Approximately 22% of the 387 orthogroups tested showed evidence of positive selection in at least one of the three branch-site tests (CODEML, BUSTED, and aBSREL). Only 12 genes could be reliably associated with a developmental function related to traits linked with coloniality, neuroanatomy, or ciliary fields. Genes testing for both positive selection and convergent molecular characters include orthologues of Radial spoke head, Elongation translation initiation factors, SEC13, and Immediate early response gene5. Maximum likelihood analyses included here resulted in tree topologies typical of other phylogenetic investigations based on wider genomic information. Further genomic and experimental evidence will be needed to resolve whether a solitary ancestor with multiciliated cells that formed aggregate groups gave rise to colonial forms in bryozoans (and perhaps the entoprocts) or that the morphological differences exhibited by phoronids and brachiopods represent trait modifications from a colonial ancestor.© 2020 Wiley Periodicals LLC.SantagataScottS0000-0002-8871-8839Department of Biological and Environmental Sciences, Long Island University, Greenvale, New York.engJournal ArticleResearch Support, U.S. Gov't, Non-P.H.S.20200708United StatesJ Exp Zool B Mol Dev Evol1011682281552-5007IMAnimalsBiological EvolutionClone CellsInvertebratesanatomy & histologyclassificationgeneticsPhylogenyTranscriptomebryozoacolonialectoproctalarvaelophotrochozoaphoronida2020051420190910202006032020796020219286020207960ppublish3263853610.1002/jez.b.22975Dokl Biol SciPeculiarities of Tentacle Innervation of Flustrellidra hispida and Evolution of Lophophore in Bryozoa.30-3310.1134/S0012496621010038The study of the lophophore organization is of great importance for the reconstruction of lophophorate phylogeny and for understanding the evolutionary transformation in each phylum of Lophophorata. The innervation of the lophophore in ctenostome bryozoan Flustrellidra hispida was studied using immunocytochemistry and confocal laser scanning microscopy. It has been demonstrated that this species has an outer nerve ring giving rise to the tentacle nerves. The outer nerve ring was earlier described in some ctenostomates and cyclostomates, but not as connected with nerves. The discovered feature of lophophore innervation in F. hispida suggests the evolutionary transformation from a hypothetical phoronida-like ancestor lophophore bearing a prominent outer nerve ring with numerous tentacle nerves emanating from it, to the complex bell-shaped lophophore of F. hispida with a well-pronounced outer nervous ring bearing a few tentacle nerves. The next one in this hypothetical row is the lophophore of the other ctenostomates and some cyclostomates with no ring-nerve connection and cheilostomates lophophore with no outer nerve ring at all.IsaevaM AMAMoscow State University, 119991, Moscow, Russia.KosevichI AIAMoscow State University, 119991, Moscow, Russia.TemerevaE NENMoscow State University, 119991, Moscow, Russia. temereva@mail.ru.engJournal Article20210226United StatesDokl Biol Sci75054590012-4966IMAnimalsBiological EvolutionBryozoaanatomy & histologyphysiologyInvertebratesphysiologyNervous System Physiological PhenomenaOrganogenesisphysiologyPhylogenyLophophorataconfocal laser scanning microscopylophophorenervous system202010012020101520201013202122612142021227602021102660ppublish3363548710.1134/S001249662101003810.1134/S0012496621010038
