Population structure and phylogenetic characterization of marine benthic Archaea in deep-sea sediments - PubMed (original) (raw)

FIG. 3

Phylogenetic analysis of deep-sea benthic Archaea. A maximum likelihood tree was constructed for the archaeal sequences by using fastDNAml (17). The scale represents the expected number of changes per sequence position. Abbreviations for the benthic Archaea (in boldface) are formed by a combination of the sampling station abbreviation, followed by the letter A (Archaea), the phylotype number, and the vertical depth interval of the sediment core from which the specific phylotype was obtained. Abbreviations for as-yet-uncultivated phylotypes from various environments: BBA (AF004343 to AF004348), from continental shelf sediments (56); JM8 (L24201), from the gut of a deep-sea sediment feeder (38); Mariana15 (D87350), from Mariana Trench sediments (31); SBAR5 (M88075), SBAR16 (M88077), OARB (U11040), WHARN (M88078), ANTARCTIC5 (U11044), pN1-2 (U86455), pN1-73 (U86462), and p712-3 (U81540), from marine picoplankton (9, 20); FFSB1 (X96688) and SCA1145 (U62811), from soil (6, 30); pGrfA4 (U59968), pGrfC26 (U59986), pGrfB286 (U59984), LMA134 (U87515), LMA238 (U87517), pLAW11 (U77569), and pLAW12 (U77568), from freshwater sediments (26, 35, 50); Arc.98 (AF005760) and Arc.168 (AF005764), from a deep-subsurface paleosol (8); pJP33 (L25300), pJP41 (L25301), pJP89 (L25305), pSL17 (U63339), pSL22 (U63340), and pSL123 (U63445), from a Yellowstone National Park hot spring (5); 2MT1 (AF015981) and 2MT8 (AF015992), from salt marsh sediments (42); and WCHD3 (AF050616), from a contaminated aquifer (14).
