Thyroid hormones (TH) are central hormonal regulators, orchestrating gene expression and complex biological processes vital for growth reproduction in variable environments by triggering specific developmental response to external cues. TH serve distinct roles different species: inducing metamorphosis amphibians or teleost fishes, governing metabolic mammals, acting as effectors of seasonality. These multifaceted raise questions about the underlying mechanisms action. Recent evidence...
Significance Developmental plasticity is defined as the ability of an organism to adjust its development depending on environmental signals, thus producing alternative phenotypes precisely adjusted environment. Yet, mechanisms underlying developmental are not fully understood. We found that juvenile clownfish delay their white bars during metamorphosis sea anemone species in which they recruited. To understand this plasticity, we investigated roles for thyroid hormones, main hormones...
Most marine organisms have a biphasic life cycle during which pelagic larvae transform into radically different juveniles. In vertebrates, the role of thyroid hormones (THs) in triggering this transition is well known, but how morphological and physiological changes are integrated coherent way with ecological remains poorly explored. To gain insight question, we performed an analysis metamorphosis teleost, false clownfish (Amphiprion ocellaris). We show THs coordinate change color vision as...
Abstract Background Anemonefish association with sea anemones is a prime example of mutualistic symbiosis. These fish live inside the anemone, benefitting from protection its toxic nematocysts, and in return, protect anemone own predators. How anemonefish manage to avoid their host stings remains unclear. One hypothesis suggests that low levels sialic acids mucus prevent nematocyst discharge. Results This study verified four predictions: (i) has lower acid than non-symbiotic damselfish; (ii)...
Actinopterygian fishes harbor at least eight distinct pigment cell types, leading to a fascinating diversity of colors. Among this diversity, the cellular origin white color appears be linked several types such as iridophores or leucophores. We used clownfish Amphiprion ocellaris, which has pattern consisting bars over darker body, characterize cells that underlie hue. observe by electron microscopy in are similar iridophores. In addition, transcriptomic signature exhibits similarities with...
Abstract Larval metamorphosis and recruitment represent critical life-history transitions for most teleost fishes. While the detrimental effects of anthropogenic stressors on behavior survival recruiting fishes are well-documented, physiological mechanisms that underpin these patterns remain unclear. Here, we use pharmacological treatments to highlight role thyroid hormones (TH) play in sensory development determining anti-predator responses metamorphosing convict surgeonfish, Acanthurus...
Edible bananas result from interspecific hybridization between Musa acuminata and balbisiana, as well among subspecies in M. acuminata. Four particular have been proposed the main contributors of edible bananas, all which radiated a short period time southeastern Asia. Clarifying evolution these lineages at whole-genome scale is therefore an important step toward understanding domestication diversification this crop. This study reports de novo genome assembly gene annotation representative...
Biologists have long been fascinated by the striking diversity of complex color patterns in tropical reef fishes. However, origins and evolution this are still poorly understood. Disentangling simple offers opportunity to dissect both ultimate proximate causes underlying diversity.Here, we study clownfishes, a tribe 30 species within Pomacentridae that displays relatively pattern made zero three vertical white stripes on dark body background. Mapping number evolutionary tree clownfishes...
Clownfishes are an iconic group of coral reef fishes, especially known for their mutualism with sea anemones.This is particularly interesting as it likely acted the key innovation that triggered clownfish adaptive radiation.Indeed, after acquisition mutualism, clownfishes diversified into multiple ecological niches linked host and habitat use.However, despite importance this genetic mechanisms allowing to interact anemones still unclear.Here, we used a comparative genomics molecular...
Most teleost fishes exhibit a biphasic life history with larval oceanic phase that is transformed into morphologically and physiologically different demersal, benthic, or pelagic juveniles. This process of transformation characterized by myriad hormone-induced changes, during the often abrupt transition between juvenile phases called metamorphosis. Thyroid hormones (TH) are known to be instrumental in triggering coordinating this but other hormonal systems such as corticoids, might also...
Lateralization, i.e. the preferential use of one side body, may convey fitness benefits for organisms within rapidly-changing environments, by optimizing separate and parallel processing different information between two brain hemispheres. In coral reef-fishes, movement larvae from planktonic to reef environments (recruitment) represents a major life-history transition. This transition requires rapidly identify respond sensory cues select suitable habitat that facilitates survival growth....
The clownfish Amphiprion ocellaris is one of the rare coral reef fish species that can be reared in aquaria. With relatively short embryonic and larval development, it could used as a model to study impact global changes such temperature rise or anthropogenic threats (eg, pollution) on postembryonic development at molecular endocrinological levels. Establishing developmental table allows us standardize sampling for scientific community willing conduct experiments this different areas:...
Understanding the relationship between coral reef condition and recruitment potential is vital for development of effective management strategies that maintain cover biodiversity. Coral larvae (planulae) have been shown to use certain sensory cues orient towards settlement habitats (e.g. odour live crustose coralline algae - CCA). However, influence auditory on recruitment, any effect anthropogenic noise this process, remain largely unknown. Here, we determined protected (MPA), exploited...
Abstract As interest increases in ecological, evolutionary, and developmental biology (Eco‐Evo‐Devo), wild species are increasingly used as experimental models. However, we still lacking a suitable model for marine fish species, well coral reef fishes that can be reared at laboratory scales. Extensive knowledge of the life cycle anemonefishes, peculiarities their biology, make them relevant models ecology, evolutionary sciences. Here, present standard methods to maintain breeding pairs...
Abstract Clownfishes and sea anemones form an intriguing long-term association, but the mechanism underlying this symbiosis is not well understood. Since clownfishes seem to cover themselves with anemone mucus, we investigated microbiomes of two partners search for possible shifts in their compositions. We used a 16S rRNA gene sequencing strategy study dynamics microbiota during association between clownfish Amphiprion ocellaris its host Heteractis magnifica under laboratory conditions. The...

To gain insight question, we performed an integrative analysis metamorphosis teleost, clownfish Amphiprion ocellaris . We reveal TH coordinate change...
