Abstract

The white-throated sparrow (Zonotrichia albicollis) known for its morphological, behavioral and chromosomal polymorphisms represents a quite new model system to study genomic mechanisms underlying variable behavioral repertoire interwoven with population biology, reproduction and adaptation in this species. It was previously shown that these polymorphisms could be due to chromosomal rearrangements (inversions) on sparrow chromosome 2 (ZAL2) that is characterized by a heterogeneity in two distinct morphs, tan (ZAL2/ZAL2) and white (ZAL2/ZAL2m). To construct a comparative genomic map of ZAL2 and other chromosomes, we used a sparrow genomic BAC library, CHORI-264. Following a cross-species overgo hybridization approach, we screened the library and developed a first-generation BAC-based comparative physical map using the chicken and zebra finch reference genomes. The map includes 640 BAC-gene assignments for 77 loci and serves for further refining the genomic regions and identifying candidate genes that are affected by rearrangements and contribute to the observed behavioral polymorphisms. Mathematical assessment of the BAC-based hybridization data was undertaken to show evolutionary relationships of avian genomes.

В настоящей работе представлена математическая оценка межвидовой БАК-гибридизации в процессе геномного картирования у белошейной зонотрихии – вида воробьев, рассматриваемого в качестве удобной модели поведения птиц.
