Special Issue Information

Dear Colleagues,

Coral reefs are incredibly diverse ecosystems, providing ecosystem services to millions of people. These ecosystems rely on the complex and often mutually beneficial relationship between corals and their associated eukaryotic and prokaryotic microorganisms, such as photosynthetic dinoflagellates, bacteria, fungi, virus, archaea, and endolithic algae.

The intricate symbioses between corals and their microorganisms play an important role in maintaining coral reef health and productivity, but it is vulnerable to various environmental stressors such as rising ocean temperatures, pollution, and ocean acidification. In recent years, significant progress has been made in understanding the intricacies of some of these associations, and the underlying mechanisms that govern their interactions. These advances have led to a deeper understanding of the molecular, physiological, and ecological basis for some of these important associations. Nevertheless, there are still significant gaps in our knowledge on the processes involved in the establishment and maintenance of coral holobiont symbioses, as well as the mechanisms through which these symbioses are affected by stress. Thus, further research is warranted, including for less-investigated microorganism groups (e.g., virus, fungi).

For this Research Topic, we seek to bring together a broad range of studies that enhance our understanding of the symbiotic association between corals and microorganisms. We welcome original studies, (mini-)reviews, and opinion papers.

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. Microorganisms is an international peer-reviewed open access monthly 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 2700 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.

The urgency of responding to climate change for corals necessitates the exploration of innovative methods to swiftly enhance our understanding of crucial processes. In this study, we employ an integrated chemical omics approach, combining elementomics, metabolomics, and volatilomics methodologies to unravel the biochemical pathways associated with the thermal response of the coral symbiont, Symbiodiniaceae Durusdinium trenchii. We outline the complimentary sampling approaches and discuss the standardised data corrections used to allow data integration and comparability. Our findings highlight the efficacy of individual methods in discerning differences in the biochemical response of D. trenchii under both control and stress-inducing temperatures. However, a deeper insight emerges when these methods are integrated, offering a more comprehensive understanding, particularly regarding oxidative stress pathways. Employing correlation network analysis enhanced the interpretation of volatile data, shedding light on the potential metabolic origins of volatiles with undescribed functions and presenting promising candidates for further exploration. Elementomics proves to be less straightforward to integrate, likely due to no net change in elements but rather elements being repurposed across compounds. The independent and integrated data from this study informs future omic profiling studies and recommends candidates for targeted research beyond Symbiodiniaceae biology. This study highlights the pivotal role of omic integration in advancing our knowledge, addressing critical gaps, and guiding future research directions in the context of climate change and coral reef preservation.
