Phylogenetic Analysis of ALV-J Associated with Immune Responses in Yellow Chicken Flocks in South China

Figure 3

Sequence analysis results of the proviral genome. (a) The four isolates have different degrees of insertions and deletions in their 5U3, env, and 3UTR regions when compared with those of the original strain HPRS-103. (b) Transcriptional regulatory elements in the 5U3 region of the four isolates. The dots (.) indicate identical residues, while the letters indicate the base substitutions. The dashes (-) indicate gaps in the alignment. Locations of deletions or insertions are boxed and marked.
