Special Issue Information

Dear Colleagues,

This Special Issue will highlight the most recent and significant advances in the molecular biology of crustaceans. The field is at a pivotal moment, where molecular approaches are not only unraveling fundamental aspects of crustacean biology but are also becoming crucial for addressing global challenges in aquaculture and conservation. As organisms of immense ecological, economic, and evolutionary importance, crustaceans have become focal modals for a wide range of molecular investigations that have been revolutionized by next-generation technologies. We invite contributions that showcase the forefront of this research. This Issue aims to bring together studies exploring the breadth of crustacean molecular biology—from genomics, transcriptomics, and phylogenomics that reveal their evolutionary history and genomic architecture to functional studies on their adaptation to environmental stressors like climate change and pollution. We are particularly interested in research that uncovers the molecular underpinnings of development, immunology, and endocrinology, which govern complex life cycles and environmental responses. Collectively, these contributions will provide a comprehensive overview of the current state of the field, fostering further exploration in this dynamic area.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Panulirus ornatus, the ornate spiny lobster, is a stenohaline weak hyper-osmoregulator, yet its osmoregulatory response to salinity stress remains poorly understood. This study investigated six osmoregulatory genes—Na+/K+-ATPase (nka), V-type H+-ATPase (vhe), Na+/HCO3 exchanger (nbc), Na+/K+/2Cl co-transporter (nkcc), Na+/H+ exchanger (nhe), and carbonic anhydrase (ca)—in juvenile gills exposed to 25 ppt, 34 ppt (control), and 40 ppt salinities during acute (48 h) and chronic (>38 d) phases. Transcriptome analysis revealed that all genes were unresponsive following either 25 ppt or 40 ppt salinity acute exposure. However, nkcc showed a tendency toward for upregulation under 25 ppt salinity during acute exposure. Additionally, glutathione S-transferase and putative ferrous reductase 1 were upregulated under 25 ppt salinity, suggesting increased metabolic demand. In contrast, glutathione peroxidase and an ammonia transporter were upregulated in 40 ppt salinity, indicating protein catabolism. Quantitative PCR confirmed nkcc- and nka upregulation under chronic 25 ppt salinity. Vhe, nbc, nhe and ca showed no response, and 40 ppt salinity did not affect the six target genes. These findings suggest P. ornatus relies on nkcc- and nka-mediated ion transport and lacks mechanisms to tolerate high salinity, resulting in reduced growth and survival. These findings define optimal salinity range for aquaculture (25–34 ppt), highlighting the need to avoid high-salinity stress in lobster water quality management Full article
