Figure 1. Phylogenetic relationships of N6 viruses.

Figure 1

Phylogenic tree of NA genes of the N6 is mid-point rooted for clarification only. Bootstrap values less than 70% are not shown, and two-star (**) represents high values (> 90%) and one-star (*) represents medium (> 70% < 90%). The bar represents nucleotide substitutions per site (subs/site). Viruses included in this study are gray. Abbreviations are as follows: BG, bean goose; CK, chicken; DK, duck; Env, environment; Gs, goose; Md, Mallard; MD, Muscovy duck; PG, Pigeon; QA, quail; SW, swine; WD, wild duck; AH, Anhui; FJ, Fujian; GD, Guangdong; GY, Guiyang; GX, Guangxi; GZ, Guizhou; HuB, Hubei; HK, Hongkong; HuN, Hunan; JS, Jiangsu; JX, Jiangxi; SC, Sichuan; SD, Shandong; SX, Shanxi; ST, Shantou; SZ, Shenzhen; XJ, Xinjiang; YN, Yunnan; ZJ, Zhejiang.
