Nuclear Genome Size Diversity Of Marine Invertebrate Taxa Using Flow Cytometric Analysis, Kyle Roebuck Dec 2017

Nuclear Genome Size Diversity Of Marine Invertebrate Taxa Using Flow Cytometric Analysis, Kyle Roebuck

HCNSO Student Theses and Dissertations

Genomic analysis provides a substantial amount of information on evolutionary history, novel genes, transcriptomic expression and regulation in response to environmental stimuli, how efficiently organisms utilize their genome, and directional genome evolution. Genome size analysis serves as the first step in the sequencing process, because sequencing and annotation costs are directly correlated with genome size. Invertebrates represent the vast majority of faunal diversity on the planet, and, to a greater extent, the marine environment, although they are vastly understudied when compared to vertebrate genomes. Flow cytometry is a widely used, reliable, and accurate means of estimating genome sizes and has …

Complete Bacterial Symbiont Genome Sequences From Anglerfish Cryptopsaras Couesii And Melanocetus Johnsonii, Lindsay L. Freed, Dana Fadera, Dante Fenolio, Tracey Sutton, Jose V. Lopez

DEEPEND Datasets

These are the complete bacterial symbiont genome sequences from anglerfish Cryptopsaras couesii (individual CC26) and one individual Melanocetus johnsonii. These data were generated and analyzed by the laboratory of Dr Tory Hendry (Cornell University). The full sequences of two symbiotic bacterial genomes have been submitted to public DDBJ/ENA/GenBank repositories under the accessions CP020660- CP020663 (CC26 Cryptopsaras couesii) and NBYY01000001-NBYY01000039 (Melanocetus johnsonii). The total genome size for each of the symbiont species is about 2-2.6 Mb.

Marine sponges (phylum Porifera) are a diverse, phylogenetically deep-branching clade known for forming intimate partnerships with complex communities of microorganisms. To date, 16S rRNA gene sequencing studies have largely utilised different extraction and amplification methodologies to target the microbial communities of a limited number of sponge species, severely limiting comparative analyses of sponge microbial diversity and structure. Here, we provide an extensive and standardised dataset that will facilitate sponge microbiome comparisons across large spatial, temporal, and environmental scales. Samples from marine sponges (n = 3569 specimens), seawater (n = 370), marine sediments (n = 65) and other …


Bacterial Communities Associated With Healthy And Diseased Acropora Cervicornis (Staghorn Coral) Using High-Throughput Sequencing, Charles Walton Jul 2017

Bacterial Communities Associated With Healthy And Diseased Acropora Cervicornis (Staghorn Coral) Using High-Throughput Sequencing, Charles Walton

HCNSO Student Theses and Dissertations

Coral diseases were first noted in the 1960s and 1970s and have had major impacts globally on coral reef community structures. In the Caribbean, a major outbreak of white band disease has been considered responsible for the drastic decline of Caribbean Acroporids since the 1970s. In addition to white band disease, another more recently described condition known as rapid tissue loss (RTL) has had major impacts on Acropora cervicornis populations, specifically offshore Broward County Southeast Florida. While these diseases have contributed to the population decline, determining their etiologies has been elusive.

Coral diseases have been characterized by shifts in their …


Dna Sequences Of The Mitochondrial Cytochrome C Oxidase I (Coi) Genes From Deep Sea Fishes. Cruises Dp01 And Dp02 From May 2015 - August 2015, Andrea Bernard, Max Weber, Kimberly A. Finnegan, Mahmood S. Shivji, Ron Eytan May 2017

DEEPEND Datasets

The deep sea ecosystem is believed to contain the highest biomass of fish in the oceans. However, the taxonomic diversity in this ecosystem is incompletely described and likely to be vastly underestimated. DNA sequence data (barcodes) have become a key tool to discover hidden biodiversity. We generated mitochondrial DNA barcode datasets based on the Cytochrome c oxidase I (COI) gene from deep sea fishes. These data were analyzed using phylogenetic and statistical methods to reveal cryptic species and make taxonomic linkages between adult fishes and their early life stages. These datasets were generated from fishes collected in the Northern Gulf …


Microbiome And Bacterioplankton Rrna Gene Sequence Data Collected From Gulf Of Mexico Seawater Samples, Cruises Dp01 And Dp02 From May 2015 - August 2015, Cole Easson, Jose V. Lopez Feb 2017

Microbiome And Bacterioplankton Rrna Gene Sequence Data Collected From Gulf Of Mexico Seawater Samples, Cruises Dp01 And Dp02 From May 2015 - August 2015, Cole Easson, Jose V. Lopez

DEEPEND Datasets

Seawater was collected and filtered for microbiome and bacterioplankton sequencing and analyses at various depths during two planned DEEPEND cruise expeditions to the GOM. Filters were stored and then processed for total environmental genomic DNA according to standard methods (see earthmicrobiome.org). 16S rRNA amplicon libraries covering the V4 hypervariable region was generated with universal PCR primers and then sequenced on an Illumina MiSeq DNA sequencing platform. Bioinformatics analyses in QIIME and R was used to quality filter and assess microbial community diversity and taxonomic composition. These baseline characterizations track alpha and beta diversity at different depths ranging from 0 – …

Background: Comparative genomic and/or transcriptomic analyses involving elasmobranchs remain limited, with genome level comparisons of the elasmobranch immune system to that of higher vertebrates, non-existent. This paper reports a comparative RNA-seq analysis of heart tissue from seven species, including four elasmobranchs and three teleosts, focusing on immunity, but concomitantly seeking to identify genetic similarities shared by the two lamnid sharks and the single billfish in our study, which could be linked to convergent evolution of regional endothermy.

Results: Across seven species, we identified an average of 10,877 Swiss-Prot annotated genes from an average of 32,474 open reading frames within each …
