A stony coral cell atlas illuminates the molecular and cellular basis of coral symbiosis, calcification, and immunity

Cell, Год журнала: 2021, Номер 184(11), С. 2973 - 2987.e18

Опубликована: Май 1, 2021

Stony corals are colonial cnidarians that sustain the most biodiverse marine ecosystems on Earth: coral reefs. Despite their ecological importance, little is known about cell types and molecular pathways underpin biology of reef-building corals. Using single-cell RNA sequencing, we define over 40 across life cycle Stylophora pistillata. We discover specialized immune cells, uncover developmental gene expression dynamics calcium-carbonate skeleton formation. By simultaneously measuring transcriptomes cells algae within them, characterize metabolic programs involved in symbiosis both partners. also trace evolution these specializations by phylogenetic integration multiple cnidarian type atlases. Overall, this study reveals cellular basis stony biology.

Stress is a central concept in biology and has now been widely used psychological, physiological, social, even environmental fields. However, the of stress was cross-utilized to refer different elements system including stressful stimulus, stressor, response, effect. Here, we summarized evolution framework system. We find although developed from Selye's "general adaptation syndrome", it expanded evolved significantly. defined as state homeostasis being challenged, both local stress. A specific stressor may potentially bring about stress, while intensity beyond threshold commonly activate hypothalamic-pituitary-adrenal axis result systematic response. The indicates that includes three types: sustress (inadequate stress), eustress (good distress (bad stress). Both might impair normal physiological functions lead pathological conditions, benefit health through hormesis-induced optimization homeostasis. Therefore, an optimal level essential for building biological shields guarantee life processes.

Coral‐bleaching responses to climate change across biological scales

Global Change Biology, Год журнала: 2022, Номер 28(14), С. 4229 - 4250

Опубликована: Апрель 27, 2022

Abstract The global impacts of climate change are evident in every marine ecosystem. On coral reefs, mass bleaching and mortality have emerged as ubiquitous responses to ocean warming, yet one the greatest challenges this epiphenomenon is linking information across scientific disciplines spatial temporal scales. Here we review some seminal recent coral‐bleaching discoveries from an ecological, physiological, molecular perspective. We also evaluate which data processes can improve predictive models provide a conceptual framework that integrates measurements biological Taking integrative approach scales, using for example hierarchical estimate major coral‐reef processes, will not only rapidly advance science but necessary guide decision‐making conservation efforts. To conserve encourage implementing mesoscale sanctuaries (thousands km 2 ) transcend national boundaries. Such networks protected reefs reef connectivity, through larval dispersal transverse thermal environments, genotypic repositories may become essential units selection environmentally diverse locations. Together, multinational be best chance corals persist change, while humanity struggles reduce emissions greenhouse gases net zero.

Coral holobiont cues prime Endozoicomonas for a symbiotic lifestyle

The ISME Journal, Год журнала: 2022, Номер 16(8), С. 1883 - 1895

Опубликована: Апрель 20, 2022

Abstract Endozoicomonas are prevalent, abundant bacterial associates of marine animals, including corals. Their role in holobiont health and functioning, however, remains poorly understood. To identify potential interactions within the coral holobiont, we characterized novel isolate marisrubri sp. nov. 6c assessed its transcriptomic proteomic response to tissue extracts native host, Red Sea Acropora humilis. We show that stimulated differential expression genes putatively involved symbiosis establishment via modulation host immune by E. 6c, such as for flagellar assembly, ankyrins, ephrins, serpins. Proteome analyses revealed upregulated vitamin B1 B6 biosynthesis glycolytic processes cues. Our results suggest priming a symbiotic lifestyle involves immunity exchange essential metabolites with other members. Consequently, may play an important nutrient cycling therefore contribute health, acclimatization, adaptation.

The coral microbiome: towards an understanding of the molecular mechanisms of coral–microbiota interactions

FEMS Microbiology Reviews, Год журнала: 2023, Номер 47(2)

Опубликована: Март 1, 2023

Corals live in a complex, multipartite symbiosis with diverse microbes across kingdoms, some of which are implicated vital functions, such as those related to resilience against climate change. However, knowledge gaps and technical challenges limit our understanding the nature functional significance complex symbiotic relationships within corals. Here, we provide an overview complexity coral microbiome focusing on taxonomic diversity functions well-studied cryptic microbes. Mining literature indicate that while corals collectively harbour third all marine bacterial phyla, known symbionts antagonists represent minute fraction this these taxa cluster into select genera, suggesting selective evolutionary mechanisms enabled bacteria gain niche holobiont. Recent advances research aimed at leveraging manipulation increase coral's fitness help mitigate heat stress-related mortality discussed. Then, insights potential through microbiota can communicate modify host responses examined by describing recognition patterns, microbially derived epigenome effector proteins gene regulation. Finally, power omics tools used study highlighted emphasis integrated host-microbiota multiomics framework understand underlying during change-driven dysbiosis.

Triggers, cascades, and endpoints: connecting the dots of coral bleaching mechanisms

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2024, Номер 99(3), С. 715 - 752

Опубликована: Янв. 12, 2024

ABSTRACT The intracellular coral–dinoflagellate symbiosis is the engine that underpins success of coral reefs, one most diverse ecosystems on planet. However, breakdown and loss microalgal symbiont (i.e. bleaching) due to environmental changes are resulting in rapid degradation reefs globally. There an urgent need understand cellular physiology bleaching at mechanistic level help develop solutions mitigate reef crisis. Here, unprecedented scope, we present novel models integrate putative mechanisms within a common framework according triggers (initiators bleaching, e.g. heat, cold, light stress, hypoxia, hyposalinity), cascades (cellular pathways, photoinhibition, unfolded protein response, nitric oxide), endpoints (mechanisms loss, apoptosis, necrosis, exocytosis/vomocytosis). supported by direct evidence from cnidarian systems, indirectly through comparative evolutionary analyses non‐cnidarian systems. With this approach, new have been established between initiated different triggers. In particular, provide insights into poorly understood connections highlight role mechanism i.e. ‘symbiolysosomal digestion’, which symbiophagy. This review also increases approachability for specialists non‐specialists mapping vast landscape atlas comprehensible detailed models. We then discuss major knowledge gaps how future research may improve understanding cascade pathways (endpoints).
