Parsimony And Model-Based Analyses Of Indels In Avian Nuclear Genes Reveal Congruent And Incongruent Phylogenetic Signals, Tamaki Yuri, Rebecca T. Kimball, John Harshman, Rauri C.K. Bowie, Michael J.

Insertion/deletion (indel) mutations, which are represented by gaps in multiple sequence alignments, have been used to examine phylogenetic hypotheses for some time. However, most analyses combine gap data with the nucleotide sequences in which they are embedded, probably because most phylogenetic datasets include few gap characters. Here, we report analyses of 12,030 gap characters from an alignment of avian nuclear genes using maximum parsimony (MP) and a simple maximum likelihood (ML) framework. Both trees were similar, and they exhibited almost all of the strongly supported relationships in the nucleotide tree, although neither gap tree supported many relationships that have proven …

Genome Empowerment For The Puerto Rican Parrot – Amazona Vittata, Stephen J. O'Brien

Biology Faculty Articles

A unique community-funded project in Puerto Rico has launched whole-genome sequencing of the critically endangered Puerto Rican Parrot (Amazona vittata), with interpretation by genome bioinformaticians and students, and deposition into public online databases. This is the first article that focuses on the whole genome of a parrot species, one endemic to the USA and recently threatened with extinction. It provides invaluable conservation tools and a vivid example of hopeful prospects for future genome assessment of so many new species. It also demonstrates inventive ways for smaller institutions to contribute to a field largely considered the domain of large …

Analysis Of The Genetic Structure Of Bithynia Tentaculata Snail Populations In Wisconsin And Minnesota, Sarah J. Whalen

All Graduate Theses, Dissertations, and Other Capstone Projects

In recent years, there have been tens of thousands of waterfowl mortalities in Wisconsin and Minnesota. An invasive species of snail, Bithynia tentaculata, is a host for the trematode parasites (Cyathocotyle bushiensis and Sphaeridiotrema globulus) that have caused these deaths. A microsatellite-enriched genomic library was detected using DNA from a B. tentaculata specimen from Lake Onalaska (Pool 7 of the Upper Mississippi River). Seven polymorphic microsatellite loci were used to genotype snails collected from Lake Butte des Morts, Shawano Lake, and Lake Onalaska in Wisconsin, as well as Lake Winnibigoshish in Minnesota. The genetic diversity of each population was measured …

An Initial Map Of Chromosomal Segmental Copy Number Variations In The Chicken, Xiaofei Wang, Samuel N. Nahashon, Tromondae K. Feaster, Ann L. Bohannon-Stewart, Nathaniel Adefope

Agricultural and Environmental Sciences Faculty Research

Background

Chromosomal segmental copy number variation (CNV) has been recently recognized as a very important source of genetic variability. Some CNV loci involve genes or conserved regulatory elements. Compelling evidence indicates that CNVs impact genome functions. The chicken is a very important farm animal species which has also served as a model for biological and biomedical research for hundreds of years. A map of CNVs in chickens could facilitate the identification of chromosomal regions that segregate for important agricultural and disease phenotypes.

Results

Ninety six CNVs were identified in three lines of chickens (Cornish Rock broiler, Leghorn and Rhode Island …

Sexual Differentiation Of The Zebra Finch Song System: Potential Roles For Sex Chromosome Genes, Michelle L. Tomaszycki, Camilla Peabody, Kirstin Replogle, David F. Clayton, Robert J. Tempelman, Juli Wade

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Recent evidence suggests that some sex differences in brain and behavior might result from direct genetic effects, and not solely the result of the organizational effects of steroid hormones. The present study examined the potential role for sex-biased gene expression during development of sexually dimorphic singing behavior and associated song nuclei in juvenile zebra finches.

Results

A microarray screen revealed more than 2400 putative genes (with a false discovery rate less than 0.05) exhibiting sex differences in the telencephalon of developing zebra finches. Increased expression in males was confirmed in 12 of 20 by qPCR using cDNA from …

Dna Sequence Of Melanocortin 1-Receptor Gene In Coturnix Japonica: Correlation With Three E Locus Alleles, E, E+, Erh, Rupali B. Ugrankar

Inquiry: The University of Arkansas Undergraduate Research Journal

The melanocortin 1-receptor (MC1-R) gene plays a key role in the expression of fur and feather color in mammals and birds by regulating the distribution of two melanin pigments: eumelanin (black/brown) and pheomelanin (red/yellow). MC1-R corresponds to the classical Extension (E) locus in mice, pigs, dogs, horses, and chickens. Three E locus alleles, the wild-type (e + ), brown (E), and redhead (e rh) have been identified in Japanese quail (Coturnix japonica). To determine if the quail E locus phenotypes were due to variation in the MC1-R gene, the coding region of the MC1-R gene was PCR amplified and DNA …

Poultry Breeds Must Be Conserved : An Ideal Small Unit, R H. Morris

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture is concerned at the rapid disapearance of some poultry breeds and strains over recent years. This trend has resulted from the disposal of flocks previously held by commercial poultry breeders and fanciers.

One way to stop the trend of disappearance of poultry breeds is for interested people to maintain a breeding flock of pure-bred poultry, making the progeny available to others.

This article describes a small unit suitable for housing breeding fowls. The unit is based on designs developed by the Department of Agriculture.
