Dense sampling of bird diversity increases power of comparative genomics

Nature ( the world’s leading multidisciplinary science journal) published an article  in which they announced a substantial step towards the dense representation of avian phylogenetic and molecular diversity, by analysing 363 genomes from 92.4% of bird families—including 267 newly sequenced genomes produced for phase II of the Bird 10,000 Genomes (B10K) Project [1]. This research also included the results of our Agapornis Genome Study [2][3].

This genomic resource will offer new perspectives on evolutionary processes in cross-species comparative analyses and assist in efforts to conserve species. In other words, this research should provide more insight into the evolution and development of the various bird species.

  1. Hello Sir,

    Henriette van der zwan in the study of genome she uses roseicollis longfeather green as a reference.
    In your opinon can use longfeather green was it the rigth choice?

    1. Paulo,
      I believe that, as a geneticist and Master in Science, Doctor van der Zwan knows what to do and I am sure that she makes the right decisions. Besides, if you also read “Development of an SNP-based parentage verification panel for lovebirds”, you will notice that we not only scanned the genome of a longfeathered A. roseicollis, but we also genotyped different SNPs in a population of 960 lovebirds across seven species. For your info – as in each research project – they pick one specimen to start with. Preferably one bird from which they also could scan the genome of the parents and grandparents. Just like this bird. And BTW believe me, if we need the advice of a Portuguese breeder, we will contact you.
      PS: please, next time use your own name (and your hotmail address) and not an alias.
