Genomic and single-cell analyses reveal genetic signatures of swimming pattern and diapause strategy in jellyfish. Nat Commun 2024; 15:5936. [PMID: 39009560 PMCID: PMC11250803 DOI: 10.1038/s41467-024-49848-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 06/21/2024] [Indexed: 07/17/2024] Open
Abstract
Jellyfish exhibit innovative swimming patterns that contribute to exploring the origins of animal locomotion. However, the genetic and cellular basis of these patterns remains unclear. Herein, we generated chromosome-level genome assemblies of two jellyfish species, Turritopsis rubra and Aurelia coerulea, which exhibit straight and free-swimming patterns, respectively. We observe positive selection of numerous genes involved in statolith formation, hair cell ciliogenesis, ciliary motility, and motor neuron function. The lineage-specific absence of otolith morphogenesis- and ciliary movement-related genes in T. rubra may be associated with homeostatic structural statocyst loss and straight swimming pattern. Notably, single-cell transcriptomic analyses covering key developmental stages reveal the enrichment of diapause-related genes in the cyst during reverse development, suggesting that the sustained diapause state favours the development of new polyps under favourable conditions. This study highlights the complex relationship between genetics, locomotion patterns and survival strategies in jellyfish, thereby providing valuable insights into the evolutionary lineages of movement and adaptation in the animal kingdom.

[PMID: 38155942 PMCID: PMC10753042 DOI: 10.1016/j.bbrep.2023.101613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/05/2023] [Accepted: 12/11/2023] [Indexed: 12/30/2023] Open
Abstract
Aim Given its excellent capability of escaping from unavoidable harm and death, Turritopsissp. (T. sp.) has captured the attention and fascination of scientists as a less conventional tool for aging research. The current study introduces a method for establishment of a research model and comprehensive transcriptomic analysis to reveal the structural and functional diversity of T. sp. Methods T. sp. medusae collected from the Pacific Ocean near Japan were reared using a common laboratory setting. Tissues of the gastrovascular cavity part (GP) and nerve ring part (NP) were collected, and total RNA was extracted. Bulk RNA-seq was performed to compare the different transcriptome landscapes between GP and NP. Results The GP fragment could be utilized for studies related to stress response and systemic senescence, while the NP fragment could be used to explore system rejuvenation, self-repair and regeneration. Conclusions As a less conventional system for aging research, by employing the most recently developed tools and techniques in the genomic revolution, comprehensive elucidation of the composition, development, and functions of T. sp. enabled us to explore the underlying mechanisms of the response to environmental stress and rejuvenation.
