ONCLUSION
The present dataset generated from Genbank and RDP databases were largely dominated
by Proteobacteria. Approximately 40% of sequences and OTUs belonged to Proteobacteria.
Our results showed that (1) nearly 56 % of the archaeal and 45% of the bacterial species-level
diversity in wetlands has been witnessed; (2) sequences from the bacterial phyla
Proteobacteria, Bacteroidetes, Chloroflexi, Firmicutes, Actinobacteria and archaeal class were
well represented by the available sequences and the corresponding microorganisms were
probably important participants in the wetland environments; (3) The global diversity
contains numerous groups for which there was no close cultured representative, especially the
majority of sequences assigned to the phyla Chloroflexi and Bacteroidetes. Therefore future
studies should utilize multiple approaches to characterize the microbial diversity and its
function in wetlands.
