No major difference was observed between the results from the BI and those from the ML test (Fig. 4B , D and F), confirming that RNA recombination probably occurred between TW and US IBVs in the 5 0terminal region of the N gene and that the phylogenetic incongruence was not caused by point mutation or variation in local evolutionary rates. We here show that the recombinant N gene was detected in all the isolated TW IBVs, supporting the participation of recombination in viral evolution and showing that a recombinant RNA virion can emerge as a local dominant strain.
