Figure 1From: Novel sequences of subgroup J avian leukosis viruses associated with hemangioma in Chinese layer hensPhylogenetic relationships of the three isolates and other strains including refenrence ALV-Js and other retroviruses based on U3 5' LTR (Figure 1A), 5' UTR (Figure 1B) and env gene (Figure 1C). Isolates marked with a black triangle are three isolates in our study, and strains marked with a black square are also hemangioma ALV-Js from GenBankBack to article page
