Strains of red fox (Vulpes vulpes) with markedly different behavioural phenotypes have been developed in the famous long-term selective breeding programme known as the Russian farm-fox experiment. Here we sequenced and assembled the red fox genome and re-sequenced a subset of foxes from the tame, aggressive and conventional farm-bred populations to identify genomic regions associated with the response to selection for behaviour. Analysis of the re-sequenced genomes identified 103 regions with either significantly decreased heterozygosity in one of the three populations or increased divergence between the populations. A strong positional candidate gene for tame behaviour was highlighted: SorCS1, which encodes …

Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly

HCNSO Student Theses and Dissertations

South Florida contains one of the largest subtropical wetlands in the world, and yet not much is known about the microbes that live in these surface waters. These microbes play an important role in chemical cycling and maintaining good water quality for both human and ecosystem health. The hydrology of Florida’s surface waters is tightly regulated with the use of canal and levee systems run by the US Army Corps of Engineers and The South Florida Water Management District. These canals run through the Everglades, agriculture, and urban environments to control water levels in Lake Okeechobee, the Water Conservation Areas, …

A comparative analysis of whole genome sequencing (WGS) and genotype calling was initiated for ten human genome samples sequenced by St. Petersburg State University Peterhof Sequencing Center and by three commercial sequencing centers outside of Russia. The sequence quality, efficiency of DNA variant and genotype calling were compared with each other and with DNA microarrays for each of ten study subjects. We assessed calling of SNPs, indels, copy number variation, and the speed of WGS throughput promised. Twenty separate QC analyses showed high similarities among the sequence quality and called genotypes. The ten genomes tested by the centers included eight …

Dental calculus (calcified dental plaque) is prevalent in archaeological skeletal collections and is a rich source of oral microbiome and host-derived ancient biomolecules. Recently, it has been proposed that dental calculus may provide a more robust environment for DNA preservation than other skeletal remains, but this has not been systematically tested. In this study, shotgun-sequenced data from paired dental calculus and dentin samples from 48 globally distributed individuals are compared using a metagenomic approach. Overall, we find DNA from dental calculus is consistently more abundant and less contaminated than DNA from dentin. The majority of DNA in dental calculus is …

Characterization Of The Bioluminescent Symbionts From Ceratioids Collected In The Gulf Of Mexico, Lindsay L. Freed

HCNSO Student Theses and Dissertations

Anglerfishes are easily one of the most popular deep-sea creatures due to their menacing appearance, extreme sexual dimorphism, parasitic mating approach, and eye catching bioluminescent lure. Unlike most bioluminescent fishes, which intrinsically generate light, female anglerfishes belonging to nine of the 11 families within the suborder Ceratioidei (deep-sea anglerfishes) have developed a symbiotic relationship with bioluminescent bacteria that are housed within the light organs. Previous molecular work had identified symbionts from two anglerfish species as novel and possibly unculturable taxa (Haygood et al., 1992), but nothing more has been revealed about the bioluminecent symbionts of ceratioids. As part of …

Pangolins, considered the most-traffcked mammals on Earth, are rapidly heading to extinction. Eight extant species of these African and Asian scale-bodied anteaters are commonly recognized, but their evolutionary relationships remain largely unexplored. Here, we present the most comprehensive phylogenetic assessment of pangolins, based on genetic variation of complete mitogenomes and 9 nuclear genes. We confrm deep divergence among Asian and African pangolins occurring not later than the Oligocene-Miocene boundary ca. 23 million years ago (Ma) (95% HPD = 18.7-27.2), limited fossil evidence suggesting dispersals from Europe. We recognize 3 genera including Manis (Asian pangolins), Smutsia (large African pangolins), and Phataginus …

Fine Grained Compositional Analysis Of Port Everglades Inlet Microbiome Using High Throughput Dna Sequencing, Lauren M. O'Connell, Song Gao, Donald S. Mccorquodale Jr., Jay M. Fleisher, Jose Lopez

Marine & Environmental Sciences Faculty Articles

Background

Similar to natural rivers, manmade inlets connect inland runoff to the ocean. Port Everglades Inlet (PEI) is a busy cargo and cruise ship port in South Florida, which can act as a source of pollution to surrounding beaches and offshore coral reefs. Understanding the composition and fluctuations of bacterioplankton communities (“microbiomes”) in major port inlets is important due to potential impacts on surrounding environments. We hypothesize seasonal microbial fluctuations, which were profiled by high throughput 16S rRNA amplicon sequencing and analysis.

Methods & Results

Surface water samples were collected every week for one year. A total of four samples …

We report a large compilation of the internal validations of the probabilistic genotyping software STRmix™. Thirty one laboratories contributed data resulting in 2825 mixtures comprising three to six donors and a wide range of multiplex, equipment, mixture proportions and templates. Previously reported trends in the LR were confirmed including less discriminatory LRs occurring both for donors and non-donors at low template (for the donor in question) and at high contributor number. We were unable to isolate an effect of allelic sharing. Any apparent effect appears to be largely confounded with increased contributor number.

Marker Of Proliferation Ki-67 Expression Is Associated With Transforming Growth Factor Beta 1 And Can Predict The Prognosis Of Patients With Hepatic B Virus-Related Hepatocellular Carcinoma, Chengkun Yang, Hao Su, Xiwen Liao, Chuangye Han, Tingdong Yu, Guangzhi Zhu, Xiangkun Wang, Cheryl Ann Winkler, Stephen J. O’Brien, Tao Peng

Biology Faculty Articles

Hepatocellular carcinoma (HCC) is the most frequent malignancy of the liver. Transforming growth factor beta 1 (TGFB1) and marker of proliferation Ki-67 (MKI67) regulate cell proliferation, differentiation, and growth. The association between MKI67 and TGFB1 expression and its clinical implications in HCC remain unknown. Methods: Public databases were used to analyze TGFB1 and MKI67 expression in different pathologic grades/stages and tissue types of HCC. The association between MKI67 and TGFB1 expression was explored using pathway analysis and in a HepG2 cell line treated with TGFB1. Survival analysis was performed to evaluate the prognostic value of TGFB1 and MKI67 expression in …

Dna Sequences Of The Mitochondrial Cytochrome C Oxidase I (Coi) Genes From Deep Sea Fishes, Cruises Dp03 And Dp04 From May 2016 - August 2016, Max Weber, Kimberly A. Finnegan, Andrea Bernard, Ron Eytan, Mahmood S. Shivji

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 …

Comparison Of Porifera Bacterial Symbiont Community Profiles Based On Host Species And Source Template, Celeste Banfill, Jose Lopez

Lopez Laboratory: Genomics & Microbial Data

The present microbiome study reports a follow up microbiome characterization of the Porifera Tree of Life (PorToL) project, which has recognized the significance of understanding the evolutionary relationships among diverse sponge taxa (Redmond et al 2012; Thacker et al, 2013; and see http://Portol.org). The aim of this research is to opportunistically expand on the work of Hill et al. (2013) to provide preliminary data that 1) compares the diversity of bacterial communities across eight sponge taxa and 2) compares the differences between DNA and cDNA (RNA) generated 16S rRNA data to distinguish active vs. non-active bacteria.

The mammalian X chromosome is characterized by high level of conservation. On the contrary the Cetartiodactyl X chromosome displays variation in morphology and G-banding pattern. It is hypothesized that X chromosome has undergone multiple rearrangements during Cetartiodactyla speciation. To investigate the evolution of this sex chromosome we have selected 26 BAC clones from cattle CHORI-240 library evenly distributed along the cattle X chromosome. High-resolution maps were obtained by fluorescence in situ hybridisation in a representative range of cetartiodactyl species from different families: pig (Suidae), gray whale (Eschrichtiidae), pilot whale (Delphinidae), hippopotamus (Hippopotamidae), Java mouse deer (Tragulidae), pronghorn (Antilocapridae), Siberian musk …
