High-throughput RNA sequencing (RNA-Seq) has transformed the ecophysiological assessment of individual plankton species and communities. However, technology generates complex data consisting millions short-read sequences that can be difficult to analyze interpret. New bioinformatics workflows are needed guide experimentation, environmental sampling, develop test hypotheses. One complexity-reducing tool been used successfully in other fields is "t-distributed Stochastic Neighbor Embedding"...

Genome structural variations within species are rare. How selective constraints preserve gene order and chromosome structure is a central question in evolutionary biology that remains unsolved. Our sequencing of several genomes the appendicularian tunicate Oikopleura dioica around globe reveals extreme genome scrambling caused by thousands chromosomal rearrangements, although showing no obvious morphological differences between these animals. The breakpoint accumulation rate an magnitude...

Assessing the impact of global warming on food web North Atlantic will require difficult-to-obtain physiological data a key copepod crustacean, Calanus finmarchicus. The de novo transcriptome presented here represents new resource for acquiring such data. It was produced from multiplexed gene libraries using RNA collected six developmental stages: embryo, early nauplius (NI-II), late (NV-VI), copepodite (CI-II), (CV) and adult (CVI) female. Over 400,000,000 paired-end reads (100 base-pairs...

Detoxification is a fundamental cellular stress defense mechanism, which allows an organism to survive or even thrive in the presence of environmental toxins and/or pollutants. The glutathione S-transferase (GST) superfamily set enzymes involved detoxification process. This highly diverse protein characterized by multiple gene duplications, with over 40 GST genes reported some insects. However, less known about marine organisms, including crustaceans. availability two de novo transcriptomes...

Abstract Organisms inhabiting high-latitude environments have evolved adaptations, such as diapause to time reproduction and growth optimize their survival. However, the physiological regulation of timing complex life histories is poorly understood, particularly for marine copepods, that at depth. A member pelagic community sub-Arctic Pacific Ocean, Neocalanus flemingeri enters in June. Egg production occurs winter/spring. In order characterize transition from egg release, females were...

Abstract In the Gulf of Maine, copepod Calanus finmarchicus co-occurs with neurotoxin-producing dinoflagellate, Alexandrium fundyense . The is resistant to this toxic alga, but little known about other effects. Gene expression profiles were used investigate physiological response females feeding for two and five days on a control diet or containing either low high dose A. responses experimental diets similar, changed between time points. At 5-days was characterized by down-regulated genes...

Highly conserved among eukaryotes, the chemical defensome protects organisms against stressors and helps to reestablish altered homeostatic state. The includes genes such as transporters (e.g., adenosine triphosphate ATP-binding cassette), phase I II detoxification enzymes, antioxidant enzymes. During their life cycle, planktonic copepods, most abundant ubiquitous metazoans on Earth, are exposed many environmental that impair survival fitness. Here, using high-quality publicly available...

Abstract Molecular tools have changed the understanding of zooplankton biodiversity, speciation, adaptation, population genetics and global patterns connectivity. However, molecular resources needed to capitalize on these advances continue be limited in comparison with those available for other eukaryotic plankton. This deficiency could addressed through an Ocean Zooplankton Open ‘Omics Project (Ocean ZOOP) that would generate de novo assembled transcriptomes hundreds metazoan plankton...

Abstract Many arthropods undergo a seasonal dormancy termed “diapause” to optimize timing of reproduction in highly environments. In the North Atlantic, copepod Calanus finmarchicus completes one three generations annually with some individuals maturing into adults, while others interrupt their development enter diapause. It is unknown which, why and when diapause program. Transcriptomic data from copepods on known programs were analyzed using dimensionality reduction gene expression...

Copepod crustaceans are an abundant and ecologically significant group whose basic biology is guided by numerous visually behaviors. These behaviors driven copepod eyes, including naupliar eyes Gicklhorn's organs, which vary widely in structure function among species. Yet little known about the molecular aspects of vision. In this study we present a general overview vision identifying phototransduction genes from newly generated publicly available RNA-sequencing data assemblies 12...
