From: Compartmentalization of the gut viral reservoir in HIV-1 infected patients
Bootstrap Neighbor-Joining tree of RT encoding sequences obtained from gut tissues. Clustering was observed of RT encoding sequences by patient and tissue but not to the same extent as observed for the Nef encoding sequences. Closer examination of the tree revealed clustering of a large number of sequences derived from the esophagus and stomach from different patients, suggesting some selection for esophagus and stomach specific RT encoding sequences. (Bootstrap values > 70 are indicated.)
