摘      要：Impact statement The applications of marker gene concatenation have been advanced to resolve the key questions in the Tree of Life.However,the interphylum evolutionary relationship between Korarchaeota of TACK(Thaumarchaeota,Aigarchaeota,Crenarchaeota,Korarchaeota)and Asgard archaea remains uncertain.We applied a marker gene ranking procedure to examine their evolutionary history.Our updated trees showed confident placements of(1)Korarchaeota as the basal branch to other TACK archaea and as a sister group to Asgard archaea;(2)Njordarchaeota at basal branch to Korarchaeota instead of within Asgard archaea.They highlight the importance of evaluating marker genes for phylogeny inference of the Archaea domain.
