Global Chicken Genome Project
During the past two decades, Kunming Institute of Zoology, Chinese Academy of Sciences (KIZ-CAS) has performed series of studies about chicken genetic diversity and domestication history (see Publications and Presentations). Now, KIZ-CAS is leading a two-phase international collaborative project to improve our current knowledge on chicken genomics.
In the phase one project, we have completed analyses 863 genomes of chickens and wild jungle fowls mostly sampled from East Eurasia, that is, the putative center of chicken domestication. The results revealed a remarkably complex picture of the early domestication and subsequent dispersal of chickens in this region (Wang et al. 2020. Cell Res).
In the phase two project, we will focus on the genomic changes of chickens during their global dispersal out of the East Eurasia. We generate additional genomes of different indigenous breeds/ecotypes as well as improved/admixed lines from Asia, Africa and Europe. The final dataset of around 2,000 genomes will be important resources for depth studies on chicken demographic trajectory, dating and wide geographic spread, as well as the genetic mechanisms underlying their breeding and response to natural/artificial selection for rapid adaptation to diversified environmental, climatic and management conditions.
