Some like it hot Coral reefs are threatened by increasing temperatures. Acute temperature increases stress and damage corals. However, more gradual changes can result in adaptation subsequent tolerance for higher Dixon et al. show that the heat currently exists across coral populations from different latitudes be inherited. Thus, natural variation may facilitate rapid among corals as our climate warms. Science , this issue p. 1460
New methods are needed for genomic-scale analysis of emerging model organisms that exemplify important biological questions but lack fully sequenced genomes. For example, there is an urgent need to understand the potential corals adapt climate change, few molecular resources available studying these processes in reef-building corals. To facilitate genomics studies and other non-model systems, we describe transcriptome sequencing using 454, as well strategies assembling a useful catalog genes...
Elevated temperatures resulting from climate change pose a clear threat to reef-building corals; however, the traits that might influence corals' survival and dispersal during remain poorly understood. Global gene expression profiling is powerful hypothesis-forming tool can help elucidate these traits. Here, we applied novel RNA-Seq protocol study molecular responses heat settlement inducers in aposymbiotic larvae of coral Acropora millepora. This analysis single full-sibling family revealed...
Corals are capable of launching diverse immune defenses at the site direct contact with pathogens, but molecular mechanisms this activity and colony-wide effects such stressors remain poorly understood. Here we compared gene expression profiles in eight healthy Acropora hyacinthus colonies against exhibiting tissue loss commonly associated white syndromes, all collected from a natural reef environment near Palau. Two types tissues were sampled diseased corals: visibly affected apparently...
Abstract Recent evidence suggests that corals can acclimatize or adapt to local stress factors through differential regulation of their gene expression. Profiling expression in from diverse environments elucidate the physiological processes may be responsible for maximizing coral fitness natural habitat and lead a better understanding coral's capacity survive effects global climate change. In an accompanying paper, we show P orites astreoides thermally different reef habitats exhibit...
Significance Flexibility in the endosymbiotic Symbiodinium community could provide reef-building corals with capacity to survive environmental change, but this may be restricted compatible host-symbiont combinations. Therefore, determining underlying molecular, cellular, and physiological processes of symbiont compatibility is critical importance for elucidating resilience adaptability coral reefs. We coupled gene expression data high-throughput metabolite profiling compare effects on sea...
Transcriptome and genome data from twenty stony coral species a selection of reference bilaterians were studied to elucidate evolutionary history. We identified genes that encode the proteins responsible for precipitation aggregation aragonite skeleton on which organisms live, revealed network environmental sensors coordinate responses host animals temperature, light, pH. Furthermore, we describe variety stress-related pathways, including apoptotic pathways allow detoxify reactive oxygen...
Abstract Understanding the potential for coral adaptation to warming seas is complicated by interactions between symbiotic partners that define stress responses and difficulties of tracking selection in natural populations. To overcome these challenges, we characterized contribution both animal host algae thermal tolerance corals have already experienced considerable on par with end‐of‐century projections most reefs. Thermal Platygyra daedalea from hot Persian Gulf where summer temperatures...
In light of the changes in precipitation and soil water availability expected with climate change, understanding mechanisms underlying plant responses to deficit is essential. Toward that end we have conducted an integrative analysis drought stress perennial C4 grass biofuel crop, Panicum virgatum (switchgrass). Responses drying re-watering were measured at transcriptional, physiological, metabolomic levels. To assess interaction moisture diel light: dark cycles, profiled gene expression...
Selective breeding increases the resilience of reef-building corals to climate warming.
Compared with understanding of biological shape and form, knowledge is sparse regarding what regulates growth body size a species. For example, the genetic physiological causes heterosis (hybrid vigor) have remained elusive for nearly century. Here, we investigate gene-expression patterns underlying in Pacific oyster (Crassostrea gigas) two partially inbred (f = 0.375) hybrid larval populations produced by reciprocal cross between families. We cloned cDNA generated 4.5 M sequence tags...
Fungus-growing ants employ several defenses against diseases, including disease-suppressing microbial biofilms on their integument and in fungal gardens. Here, we compare the phenology of microbiomes natural nests temperate fungus-growing ant Trachymyrmex septentrionalis using culture-dependent isolations culture-independent 16S-amplicon 454-sequencing. 454-sequencing revealed diverse actinobacteria associated with ants, most prominently Solirubrobacter (12.2–30.9% sequence reads),...
Abstract Scleractinian corals occur in tropical regions near their upper thermal limits and are severely threatened by rising ocean temperatures. However, several recent studies have shown coral populations can harbour genetic variation tolerance. Here, we extended these approaches to study heat tolerance of the Persian/Arabian Gulf, where heat‐tolerant local experience extreme summer temperatures (up 36°C). To evaluate whether selection has depleted tolerance, estimate potential future...
Many nonmodel species exemplify important biological questions but lack the sequence resources required to study genes and genomic regions underlying traits of interest. Reef-building corals are famously sensitive rising seawater temperatures, motivating ongoing research into their stress responses long-term prospects in a changing climate. A comprehensive understanding these processes will require extending beyond sequenced coral genome (Acropora digitifera) encompass diverse related...
Growth rates in animals are governed by a wide range of biological factors, many which remain poorly understood. To identify the genes that establish growth differences bivalve larvae, we compared expression patterns contrasting phenotypes (slow- and fast-growth) were experimentally produced genetic crosses Pacific oyster Crassostrea gigas. Based on transcriptomic profiling 4.5 million cDNA sequence tags, sequenced annotated 181 clones identified statistical analysis as candidates for...
The emerging field of next-generation sequencing (NGs) is rapidly expanding capabilities for cutting edge genomic research, with applications that can help meet marine conservation challenges food security, biodiversity loss, and climate change.Navigating the use these tools, however, complex at best.Furthermore, questions are limited in developing nations where both threats to most concentrated.This particularly true southeast Asia.The first Pan-Pacific Advanced studies Institute (PacAsI)...
Summary The process of plant speciation often involves the evolution divergent ecotypes in response to differences soil water availability between habitats. While same set traits is frequently associated with xeric/mesic ecotype divergence, it unknown whether those evolve independently or if they tandem as a result genetic colocalization either by pleiotropy linkage. self‐fertilizing C 4 grass species Panicum hallii includes two major found xeric (var. ) mesic filipes We constructed first...
Reef-building corals are highly sensitive to rising ocean temperatures, and substantial adaptation will be required for the ecosystems they support persist in changing conditions. Genetic variation that might adaptive responses has been measured larval stages of some corals, but these estimates remain unavailable adult functional basis this remains unclear. In study, we focused on potential Orbicella faveolata, a dominant reef-builder Caribbean. We conducted thermal stress experiments using...
Worldwide, coral reefs are in decline due to a range of anthropogenic disturbances, and now also under threat from global climate change. Virtually nothing is currently known about the genetic factors that might determine whether corals adapt changing or continue decline. Quantitative genetics studies aiming identify adaptively important genomic loci will require high-resolution linkage map. The phylogenetic position suggests applications for map ancestral metazoan genome architecture.We...
