From: Salinity of irrigation water selects distinct bacterial communities associated with date palm (Phoenix dactylifera L.) root

Figure 4

Non-metric multidimensional scaling (NMDS) ordination analysis for date palm roots-associated bacterial communities between irrigation sources (non-saline freshwater vs saline groundwater). (a) The sample-based ordination plot was generated from total Operational Taxonomic Units (OTUs) compositions. The different colours in a (a) are coded according to irrigation source, and in a panel, (b) coded according to bacterial phyla. The ellipse represents 95% confidence interval for the tested factor variable (i.e., irrigation source), and arrows point in the direction of maximum increase of individual vector variables and had significant effects (P < 0.05) on the ordination configuration. (b) Species plots of overall bacteria was also based on total OTUs composition, but the most common 20 OTUs are visualized. The size of the circles in panel b shows the relative abundance of the OTUs.
