Characteristic T-RFs of bacterial communities in the estuary, coastal and open-sea sediment samples and in the sediment samples from different depths.

Abstract

<p>Distance-based discriminant analysis was performed on bacterial T-RF data (produced by HaeIII), which were divided into <i>a priori</i> groups of (A) estuary, coastal and open-sea sediments as well as (B) depth classes. Taxonomic assignments of T-RFs (refer to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0067061#pone.0067061.s005" target="_blank">Table S2</a>): Black numbers = <i>Alphaproteobacteria</i>, <i>Flavobacteria</i>, <i>Gammaproteobacteria</i> and/or <i>Sphingobacteria</i> (each T-RF represented more than one taxon), red numbers = <i>Chloroflexi</i> (mainly family <i>Anaerolineaceae</i>), green numbers = <i>Deltaproteobacteria</i>; sulphate reducing taxa, orange numbers = <i>Betaproteobacteria</i>, violet numers = <i>Clostridia</i>, and light blue numbers = <i>Planctomycetes</i>. Only those T-RFs that affected the differentiation of a <i>priori groups</i> (canonical scores of discriminant axes 1 and 2 were above 1.0) and which belonged to the most common bacterial groups in each <i>a priori</i> group were included.</p
