Specific archaeal communities are selected on the root surfaces of ruppia spp. and phragmites australis

Archaea, although being active members of microbial communities, have been poorly characterized in the rhizoplane of wetland plants. In this study, we compared the archaeal communities found on the root surface of Ruppia spp. and Phragmites australis. Four lagoons, two euhaline andtwo oligohaline, w...
