A new species of Syllis Grube, 1850 including transcriptomic data and an updated phylogeny of Syllinae (Annelida: Syllidae)
No full textSex-specific gene expression differences in reproducing Syllis prolifera and Nudisyllis pulligera (Annelida, Syllidae)
No full textSyllidae is an annelid family characterized by its complex life cycles involving some of the most outstanding annelid reproductive strategies. Syllid reproductive modes sometimes imply the modification of the posterior body to form independent reproductive units (schizogamy) or the development of swimming adults (epigamy). These modes of sexual reproduction have been studied for more than 150 years, and yet, little is known regarding their molecular background. Notably, while several studies during the last three decades have revealed details about molecular mechanisms involved in the reproduction of some few model annelids, studies focusing on syllids remain limited. Thus, we performed differential gene expression analyses of female, male, and non-reproducing individuals of Syllis prolifera (schizogamic) and Nudisyllis pulligera (epigamic), as representatives of two different reproductive strategies. For that, transcriptomes from specimens of three conditions (non-reproducing, male, female) were de novo assembled and annotated for S. prolifera and N. pulligera. We found rather similar gene expression profiles for female and non-reproducing individuals, while male gene expression is clearly different. Although previous studies have suggested that femininity in syllids might require additional signalling, our analyses support a scenario, where masculinity may also involve several specific genetic processes
