Stress Response in Diatoms: Insights into Metabolic Pathway Modulation by Omics Approaches

Dear Colleagues,

Diatoms are widespread eukaryotic unicellular organisms, colonizing every kind of acquatic environment. Their capability to adapt to highly different and even extreme habitats is the key to their ecological success. These microalgae account at least for 200,000 species, and despite the large number of ongoing studies, they are still poorly investigated, their metabolic potential still waiting to be discovered. Recent multiomics technologies have revolutioned the ways these living organisms can be studied. The acquisition of a huge amount of data with the support of dedicated software and bionformatic tools has significatively improved our knowledge and understanding of the adaptation strategies of this important microalgal group. Furthermore, the analysis of transcriptomes has allowed us to predict the occurrence of several classes of secondary metabolites, including prostaglandins and terpenoid derivatives, which in few cases have also been confirmed by chemical analysis.

This Special Issue aims at collecting contributions describing how diatoms adapt their metabolism and signaling to survive in a challenging environment. In particular, the focus will be on the integration of omics technologies to elucidate metabolite biosynthesis, modulation, and role in the aquatic environment.

We invite researchers employing genomics, transcriptomics, metabolomics, and lipidomics in conjunction with bioinformatics tools to contribute papers on diatom metabolism and signaling in response to biotic and abiotic stresses.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Phycology is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). 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.
