Partial sequences were obtained from 2 additional samples, A/swine/Minnesota/340304/2010(H1N2) (sw/MN/340304/10), and A/swine/Minnesota/226128/2010(H1N1) (sw/MN/226128/10).

What would happen if this M found its way into H5N1?

Nonsense. The question is on reassortment, not single nucleotide changes.

That is a good question. For the trH3N2 sub-clade, the swap is between different M's found in triple reassortants. The polymerase cpmplex first formed in the 1990's and the version in pandemic H1N1 has evolved independently, so the M gene in pandmeic H1N1 is distinct from the M in North American triple reassortants, but swapping still involes triple reassortants with the same general polynmerase complex (human PB1 and avian PA and PB2).

Thus, it is not clear how well a pandemic H1N1 M gene would interact with the internal H5N1 genes, although in general H1N1 genes are closer to H5N1 than seasonal H3N2 genes,

Thanks.

Looks like it was pretty quiet down here this winter - I wonder what your winter will bring with trH3N2?

Recent H1N2, A/swine/Illinois/A00907647/2011, with M gene from pandemic H1N1 and N2 cloely related to recent trH3N2 sequences.
