摘      要：Although the microbial diversity of the Indian Ocean has been extensively investigated,little is known about the community composition of microbes in the Southern Indian *** the present study,we divided 60 water column samples on the Ninety-East Ridge(NER)into fi ve water masses according to the temperature-salinity *** presented,for the fi rst time,a full description of the microbial biodiversity on NER through high-throughput amplicon sequencing approach,including bacteria,archaea,and *** found that bacteria exhibited higher richness and diversity than archaea and fungi across the water masses on *** importantly,each water mass on NER featured distinct prokaryotic microbial communities,as indicated by the results of non-metric multidimensional *** contrast,fungi were eurybathic across the water *** analysis results demonstrated that environmental factors might play a pivotal role in the formation and stability of prokaryotic communities in each water mass,especially that of *** addition,indicator species might be used as fi ngerprints to identify corresponding water masses on *** results provide new insights into the vertical distribution,structure,and diversity of microorganisms on NER from the perspective of water mass.
