    Comparative BAC-based mapping in the white-throated sparrow, a novel behavioral genomics model, using interspecies overgo hybridization

    BACKGROUND The genomics era has produced an arsenal of resources from sequenced organisms allowing researchers to target species that do not have comparable mapping and sequence information. These new "non-model" organisms offer unique opportunities to examine environmental effects on genomic patterns and processes. Here we use comparative mapping as a first step in characterizing the genome organization of a novel animal model, the white-throated sparrow (Zonotrichia albicollis), which occurs as white or tan morphs that exhibit alternative behaviors and physiology. Morph is determined by the presence or absence of a complex chromosomal rearrangement. This species is an ideal model for behavioral genomics because the association between genotype and phenotype is absolute, making it possible to identify the genomic bases of phenotypic variation. FINDINGS We initiated a genomic study in this species by characterizing the white-throated sparrow BAC library via filter hybridization with overgo probes designed for the chicken, turkey, and zebra finch. Cross-species hybridization resulted in 640 positive sparrow BACs assigned to 77 chicken loci across almost all macro-and microchromosomes, with a focus on the chromosomes associated with morph. Out of 216 overgos, 36% of the probes hybridized successfully, with an average number of 3.0 positive sparrow BACs per overgo. CONCLUSIONS These data will be utilized for determining chromosomal architecture and for fine-scale mapping of candidate genes associated with phenotypic differences. Our research confirms the utility of interspecies hybridization for developing comparative maps in other non-model organisms

    No full text
    Margaret Sparrow was born in Baltimore, Maryland. She earned her undergraduate degree from Goucher College in 1950 and her graduate degree in political science from Johns Hopkins University. Sparrow served as the executive director of the Baltimore Council of Fire Girls from 1955 until 1965. After moving to White Plains, New York, Sparrow took a position as the executive director pf the Southwest Connecticut Girl Scout Council for 5 years. She spent the remainder of her career as an executive director of the Constituent Leagues for the National League for Nursing in New York. Sparrow was also active in Republican politics and ran for a spot on the Baltimore City Council in 1950. In this history, Sparrow talks about her life, growing up in Baltimore, and Girl Scouts. This oral history is part of the Mame Warren oral histories series
