Phylogenetic analysis of STLV tax-rex sequences. PTLV phylogeny inferred using 220-bp tax-rex sequences. Reference sequences used were as follow: HTLV-1 (RKI3Ger_AF042071, TSP-1_M86840, HS35_AF033817, BOI_L36905, MT2_L03561, ATK-1_j02029, ATL-YS_U19949, WHP_AF259264, EL_M67514, MEL5_L02534), STLV-1 (Cce01CM1374_ AM746629, Cce01CM3020_ AM746632, Cpo01CM2324_ AM746633, Cpo01CM2230_ AM746634, Cni01CM4078_ AM746635, Cce01CM2141_ AM746636, Cce01CM1445_ AM746638, Cce01CM2205_ AM746639, Cni01CM2198_ AM746640, Mta 00cm265_AY496616, Tan90_AF074966, Cta01CMS75_AY496618, Cpo99cm190_AY496615, Cpo01cm1228_AY496612, Mnd 98cmB111_AY496617, Cni01cm1040_AY496608, Cag01cm1312_AY496614, Cag 01cm1135_AY496610, TE4_Z46900), HTLV-II (GAB_Y13051, GU_X89270, NRA-P_L20734, G12_l11456, Efe2_Y14365, G2_AF074965, RP329_AF326583, SP-WV_AF139382, k96_AF326584, Mo_M10060), STLV-2 (PanP_U90557, PP1664_NC001815), HTLV-3 (Pyl 43_DQ020492), STLV-3 (Lal01CM2008_ AM746647, Lal01CM4009_ AM746650, Cag02CM4101, PPA-F3_AF5177775, PH969_Y07616, TGE-2117_AY217650, hyb2210_AF378162, CTO-604_NC003323, Pha7550_AF378160, Cag01cm1184_AY496593, Cni227_AF412120,Cni217_ AY039033), HTLV-4 (1863LE_NC_011800), STLV-5 (MarB43_AY590142). Numbers correspond to internal branch support derived from 1000 bootstrap replicates (only values above ≥ 80% are shown and represented by an asterisk). Scale bar represents the number of nucleotide substitutions per site. Groves’ primate taxonomy nomenclature is used [40]. Non-human primates are coded using the first letter of the genus followed by the first two letters of the species name: Cni = Cercopithecus nictitans, Cce = Cercopithecus cephus, Msp = Mandrillus sphinx, Cto = Cercocebus torquatus, Cpo = Cercopithecus pogonias. Sequences in bold text and in grey rectangles are from the current study.
