Re: Nature Genetics. The duck genome and transcriptome provide insight into an avian influenza virus reservoir species
I saw this only after I had posted to the French thread

anas platyrhynchos is the mallard. ---10-week-old female Beijing duck ----
We were wondering whether the Asian domestic ducks were different
in that they can get viruses that evolved away from the index,
which we didn't see in North American mallards.
Well, it could just be because domestic ducks or commercial ducks
are not popular in North America.

I didn't find the chromosomes in fasta-format yet
I'm not sure whether and when they will be available.
Do I understand correctly, that they have influenza-specific genes, which evolved
since mallards get influenza ? But that's supposed to be only some thousand years ?!?
While DNA changes are more slowly. When we dig out the bones of a mallard that died
>10000 years ago, might that show us whether mallards got flu 10000 years ago ?

Anas zonorhyncha in Asia, "spot billed duck"

Abstract
The duck (Anas platyrhynchos) is one of the principal natural hosts of influenza A viruses. We present the duck genome sequence and perform deep transcriptome analyses to investigate immune-related genes. Our data indicate that the duck possesses a contractive immune gene repertoire, as in chicken and zebra finch, and this repertoire has been shaped through lineage-specific duplications. We identify genes that are responsive to influenza A viruses using the lung transcriptomes of control ducks and ones that were infected with either a highly pathogenic (A/duck/Hubei/49/05) or a weakly pathogenic (A/goose/Hubei/65/05) H5N1 virus. Further, we show how the duck's defense mechanisms against influenza infection have been optimized through the diversification of its β-defensin and butyrophilin-like repertoires. These analyses, in combination with the genomic and transcriptomic data, provide a resource for characterizing the interaction between host and influenza viruses.

N.L., J.W., Y.H. and D.W.B. organized the committee for the duck genome sequencing project. N.L., J.W., Y.H., X.H., L.R. and J.F. designed the duck genome sequence project. J.W., W.Q., Y.L. and Y. Zhang sequenced and assembled the duck genome. W.Q., Y.H., A.V. and T.F. assessed the quality of the duck genome. J.L., W.Q., S.F., Y.H., B.L., A.V., S.S., Yiqiang Zhao, Z.D., Q.C., H.T., S.B., S.K., M. Marz, M. Morisson, M.R., F.P. and P.F.S. performed gene prediction and annotation. D.W.B., H.K., Y.H., B.L., J.H., T.L., K.-W.K., J.S. and D.K.G. performed gene evolutionary analysis. Y.H., W.Q., D.W.B., Q.L., Z.D., Z.S., Y.A. and P.K. detected expansion and contraction of immune-related genes. Y.H., N.L., S.G., W.Q., Z.S. and Y.A. analyzed β-defensin and immunoglobulin genes. Y.H., N.L., H.C., K.Y., H.F., P.Z., D.W.B., K.E.M., R.G.W., J.R.A. and W.C.W. characterized the immune-related gene response to avian influenza viruses. Y.H. and W.Q. wrote the manuscript.
