Host-microbe interactions play crucial roles in marine ecosystems. However, we still have very little understanding of the mechanisms that govern these relationships, evolutionary processes shape them, and their ecological consequences. The holobiont concept is a renewed paradigm biology can help to describe understand complex systems.

Algal volatiles – the overlooked chemical language of aquatic primary producers

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2022, Номер 97(6), С. 2162 - 2173

Опубликована: Авг. 1, 2022

ABSTRACT Volatiles are important ‘infochemicals’ that play a crucial role in structuring life on our planet, fulfilling diverse functions natural and artificial systems. Algae contribute significant quantities to the global budget of volatiles, but ecological roles aquatic volatiles not well understood. In this review, we discuss current knowledge volatile compounds from freshwater marine microalgae macroalgae, with focus their roles. We highlight multiple reported biogenic ranging intraspecific communication for reproduction, intra‐bloom signalling antioxidant functions, various interspecific signal exchanges may allow herbivores locate them function defence against competitors predators. Beyond reviewing understanding, specifically major gaps emerging questions algal research. These novel perspectives have potential improve understanding ecosystems thus need be addressed future Filling these addressing will facilitate humanity's efforts exploit applications.

Progress and future directions for seaweed holobiont research

New Phytologist, Год журнала: 2024, Номер 244(2), С. 364 - 376

Опубликована: Авг. 13, 2024

In the marine environment, seaweeds (i.e. macroalgae) provide a wide range of ecological services and economic benefits. Like land plants, do not these in isolation, rather they rely on their associated microbial communities, which together with host form seaweed holobiont. However, there is poor understanding mechanisms shaping complex seaweed-microbe interactions, evolutionary processes underlying interactions. Here, we identify current research challenges opportunities field holobiont biology. We argue that identifying key partners, knowing how are recruited, specific function relevance across all life history stages among knowledge gaps particularly important to address, especially context environmental threatening seaweeds. further discuss future approaches study holobionts, can apply concept natural or engineered ecosystems.

Becoming nose‐blind—Climate change impacts on chemical communication

Global Change Biology, Год журнала: 2022, Номер 28(15), С. 4495 - 4505

Опубликована: Май 16, 2022

Chemical communication via infochemicals plays a pivotal role in ecological interactions, allowing organisms to sense their environment, locate predators, food, habitats, or mates. A growing number of studies suggest that climate change-associated stressors can modify these chemically mediated causing info-disruption scales up the ecosystem level. However, our understanding underlying mechanisms is scarce. Evidenced by range examples, we illustrate this opinion piece change affects different realms similar patterns, from molecular ecosystem-wide levels. We assess importance for terrestrial, freshwater, and marine ecosystems propose systematic approach address highlighted knowledge gaps cross-disciplinary research avenues.

High-temperature stress induces bacteria-specific adverse and reversible effects on Ulva (Chlorophyta) growth and its chemosphere in a reductionist model system

Botanica Marina, Год журнала: 2023, Номер 67(2), С. 131 - 138

Опубликована: Окт. 27, 2023

Abstract Axenic cultures of the green seaweed Ulva mutabilis were inoculated with bacteria providing essential algal growth and morphogenesis-promoting factors (AGMPFs) exposed to temperature shifts from 18 °C 30 °C. The temperature-dependent effect on longitudinal molecular composition chemosphere in culture medium was explored. reductionist tripartite model system U. , Roseovarius sp. MS2, Maribacter MS6 applied as a reference has been changed by substituting isolates that phenocopy this strain. Rathayibacter festucae IH2 aestuarii G8 boosted at but slowed it down Additional inoculation MS2 mitigated these adverse bacterial effects partially. At °C, profile differed dramatically between all tested communities, indicating different traits same bacterium changing temperatures. Functional examinations should, therefore, accompany microbiome analysis detect composition.

Circadian migrations of cave-dwelling crustaceans guided by their home chemical seascape

Organisms release and detect molecules for defense, reproduction, feeding strategies finding suitable habitats. For some migratory species, homing behavior could be related to the recognition of their home chemical fingerprint made an assemblage from habitat. In marine realm, functioning ecosystems such as underwater caves largely depends on trophic interactions between outside environment. A key feature these relies circadian migration small crustaceans (Mysida) cave habitat open sea. Recently, it has been hypothesized that migrations involve mediation. Behavioral experiments using a two-choice system have shown mysids significantly seawater rather than control water Here, we used same experimental investigate by two populations mysid Hemimysis margalefi . Both were submitted choice three distinct seawaters vs. seawater. Additionally, tested preference non-cave species ( Leptomysis sp.) seawaters. To evaluate whether was influenced cues conspecifics, complementary experiment H. conducted. Results demonstrated each studied population recognizes its own habitat, this is not occurrence ’s exudates. Mass spectrometry-based metabolomic analyses revealed had specific with only few reproducibly detected signals belonging different classes: peptides, alkaloids, fatty acids, steroids but also inorganic molecules.

Abstract Aquatic organisms detect chemical cues to sense the local environment, for example, find a mate, locate food, and identify danger. Knowledge of can be used in aquaculture, practical applications such as controlling mating behavior increase fertility, enhance feeding, decrease stress; fisheries, by catching selected species with low-cost artificial attractants; address maritime issues, decreasing biofouling. also related global environmental changes, ocean acidification, increases plastics, all which affect their chemosensory behaviors. Here we discuss nature biology ecology aquatic organisms, potential an emphasis on sex pheromones commercially important well-studied animals, namely, decapod crustaceans fish.

Infochemicals in terrestrial plants and seaweed holobionts: current and future trends

New Phytologist, Год журнала: 2020, Номер 229(4), С. 1852 - 1860

Опубликована: Сен. 28, 2020

Since the holobiont concept came into limelight ten years ago, we have become aware that responses of holobionts to climate change stressors may be driven by shifts in microbiota. However, complex interactions underlying across aquatic and terrestrial ecosystems remain largely unresolved. One key factors driving these is infochemical-mediated communication holobiont. In order come up with a holistic picture, this Viewpoint compare mechanisms infochemicals rhizosphere plants eco-chemosphere seaweeds response other environmental stressors, including drought, warming nutrient stress. Furthermore, discuss inclusion chemical ecology concepts are crucial importance survival, adaptation and/or breakdown. Infochemicals can thus regarded as 'missing link' our understanding should investigated while investigating plant seaweed change. This will set basis for improving ecosystems.
