- Background Transposable elements (TEs) widely contribute to the evolution of genomes allowing genomic innovations, generating germinal and somatic heterogeneity, and giving birth to long non-coding RNAs (lncRNAs). These features have been associated to the evolution, functioning, and complexity of the nervous system at such a level that somatic retrotransposition of long interspersed element (LINE) L1 has been proposed to be associated to human cognition. Among invertebrates, octopuses are fascinating animals whose nervous system reaches a high level of complexity achieving sophisticated cognitive abilities. The sequencing of the genome of the Octopus bimaculoides revealed a striking expansion of TEs which were proposed to have contributed to the evolution of its complex nervous system. We recently found a similar expansion also in the genome of Octopus vulgaris. However, a specific search for the existence and the transcription of full-length transpositionally competent TEs has not been performed in this genus. Results Here, we report the identification of LINE elements competent for retrotransposition in Octopus vulgaris and Octopus bimaculoides and show evidence suggesting that they might be transcribed and determine germline and somatic polymorphisms especially in the brain. Transcription and translation measured for one of these elements resulted in specific signals in neurons belonging to areas associated with behavioral plasticity. We also report the transcription of thousands of lncRNAs and the pervasive inclusion of TE fragments in the transcriptomes of both Octopus species, further testifying the crucial activity of TEs in the evolution of the octopus genomes. Conclusions The neural transcriptome of the octopus shows the transcription of thousands of putative lncRNAs and of a full-length LINE element belonging to the RTE class. We speculate that a convergent evolutionary process involving retrotransposons activity in the brain has been important for the evolution of sophisticated cognitive abilities in this genus.

Multi-Stakeholder Initiatives on Sustainability: A Cross-Disciplinary Review and Research Agenda for Business Ethics

Tidskriftsartikel (refereegranskat)abstract
- Although the literature on multi-stakeholder initiatives for sustainability has grown in recent years, it is scattered across several academic fields, making it hard to ascertain how individual disciplines, such as business ethics, can further contribute to the debate. Based on an extensive review of the literature on certification and principle-based MSIs for sustainability (n = 293 articles), we show that the scholarly debate rests on three broad themes (the 3Is): the input into creating and governing MSIs; the institutionalization of MSIs; and the impact that relevant initiatives create. While our discussion reveals the theoretical underpinnings of the 3Is, it also shows that a number of research challenges related to business ethics remain unaddressed. We unpack these challenges and suggest how scholars can utilize theoretical insights in business ethics to push the boundaries of the field. Finally, we also discuss what business ethics research can gain from theory development in the MSI field.
