The alignment of HA protein of 4 viruses from different origins. The gene sequence of HA of A/Huizhou/1/2013(H7N9) and A/environment/Guangdong/25/2013 (H7N9) was sequenced by GDCDC. The gene sequence of HA of A/chicken/Jiangsu/SC537/2013 (H7N9) [GenBank:CY146940.1] and A/chicken/SD641/Guangdong/2013 [GenBank:CY146908.1] were retrieved from GenBank. The similarity of the nucleotide sequence was 99.5-99.8% to the HA gene and there are 3 different amino acids sites of R65K, T140A and N285D of the HA protein among the 4 viruses.
