Figure 2 Rhizosphere secretions in different soil samples.
Note: H- high salinity; M- moderate salinity; L- low salinity; R- rhizosphere soil; NR- bulk soil; CK- highly saline unplanted control soil. The data are means (n=5). (A) Stacked histograms of the relative proportions of various compounds in different soil samples. The percentages greater than 1% are shown only. (B), (C), (D) Histograms of relative proportions and significant differences in specific rhizosphere secretions in different soil samples. Different lower case letters denote significant differences among different soil sample types for a given secretion (p ≤0.05).
Figure 3 Diversity of soil autotrophic bacteria based oncbbL and cbbM sequencing.
Note: H- high salinity; M- moderate salinity; L- low salinity; R- rhizosphere soil; NR- bulk soil; CK- highly saline unplanted control soil. The data are means (n=5). (A) and (C) Alpha diversity indices of autotrophic bacteria containing cbbL (A) and cbbM (C). (B) and (D) Doughnuts of the abundance of genera of autotrophic bacteria containing cbbL (B) and cbbM (D). (E) and (F) Stacked histograms of the relative proportions of different genera of autotrophic bacteria containing cbbL (E) and cbbM (F). (G) and (H) LDA Effect Size (LEfSe) of autotrophic bacteria containingcbbL (G) and cbbM (H).
