Project description:The maternal phylogeny and genomic characterization of the Iraqi chukar partridge (Alectoris chukar) using whole genome sequencing (WGS) data
Project description:The Alectoris Chukar (chukar) is the most geographically widespread partridge species in the world, demonstrating exceptional adaptability to diverse ecological environments. However, the scarcity of genetic resources for chukar has hindered research into its adaptive evolution and molecular breeding. In this study, we have sequenced and assembled a high-quality, phased chukar genome that consists of 31 pairs of relatively complete diploid chromosomes. Our BUSCO analysis reported a high completeness score of 96.8% and 96.5%, with respect to universal single-copy orthologs and a low duplication rate (0.3% and 0.5%) for two assemblies. Through resequencing and population genomic analyses of six subspecies, we have curated invaluable genotype data that underscores the adaptive evolution of chukar in response to both arid and high-altitude environments. These data will significantly contribute to research on how chukars adaptively evolve to cope with desertification and alpine climates.
Project description:The complete mitochondrial genome of Helan Mountain chukar (Alectoris chukar potanini) was first determined. The genome was 16,685 bp in length, comprising 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a putative control region. The phylogenetic analysis based on the complete mitochondrial genome sequences revealed a close relationship between A. chukar potanini and Tetraogallus tibetanus. This work is expected to provide a set of fundamental data on further genetic studies of this protected species.
