Fig 2. Maximum clade credibility (MCC) trees representing the rooted genealogy of CRF01_AE and CRF07_BC among MSM in Shanghai.
2A: the MCC tree for CRF01_AE strain. HIV-1 A1 sequences from Uganda(UG), Rwanda(RW), Australia(AU) and HIV-1 CRF01_AE sequences from Thailand (TH) were used as the references, including UG.92.AB253429, AU.03.DQ676872, RW.92.AB253421, TH.93.051, TH.90.U54771, TH.96.02138, TH.97.1695, TH.98.1251, TH.99.4460, and TH.01.2570. Blue lines represent A1 from UG, RW, AU and red lines represent CRF01_AE from TH. I, II, and III represent three clusters belonging to CRF01_AE strain. 2B: the MCC tree for CRF07_BC strain. HIV-1 subtype C sequence from Indian (IN), Ethiopia (ET), South Africa (ZA), and CRF07_BC sequence from Xinjiang, China (CNEF) were used as the reference, including IN.95.21068, ET.86.368370, ZA.04.AY772699, CNEF.05.368370, CNEF.05.368372. Blue lines represent subtype C from IN, ET, ZA and red lines represent CRF07_BC from CNEF. The branch lengths in the MCC tress reflect time and corresponding time-scale is shown at the bottom of the trees. Both the posterior probabilities and the tMRCA for the key nodes are indicated.
