The probable reassortment history of human infected AIV H5N6 in China, 2014-2015*. 1, A/Sichuan/26221/2014(H5N6); 2, A/Guangzhou/39715/2014(H5N6); 3, A/Yunnan/0127/2015(H5N6); 4, A/duck/Shantou/6233/2004(H6N6); 5, A/Guangxi/1/2005(H5N1) or A/duck/Vietnam/215/2005(H5N1) and so on; 6, A/duck/Fujian/3242/2007(H6N6); 7, A/chicken/Hebei/DF/2008(H9N2); 8, A/goose/Shandong/k1201/2009(H5N1); 9, A/chicken/Jiangsu/B20/2011(H9N2); 10, A/duck/Eastern_China/1111/2011(H5N2); 11, A/wild duck/Fujian/1/2011(H5N1); 12, A/Jiangxi-Donghu/346-2/2013(H10N8); 13, A/Zhejiang/DTID-ZJU01/2013(H7N9). *Notes: (1) Each donor isolate represents one class of isolates in the same period, which was determined with the BLAST program on NCBI website and large-scale phylogenetic analysis (See online support materials); (2) Six internal segments of H10N8 and H7N9 in China since 2013 had common donors as AIV A/Yunnan/0127/2015(H5N6) in China
