Fig 4 Observed plant-microbiota network structure for each main
vegetation type sampled in this study. In each network of (a )
desert steppe (DS) (8 plants and 25 fungi), (b ) alpine meadow
(AM) (21 plants and 118 fungi), and (c ) alpine steppe (AS) (28
plants and 138 fungi), (d ) desert steppe (DS) (13 plants and
139 bacteria), (e ) alpine meadow (AM) (21 plants and 84
bacteria), and (f ) alpine steppe (AS) (6 plants and 15
bacteria), fungi (yellow) and bacteria (purple) are linked with their
host plants (green). The size of circles represents the degree of
microbiota or plants in each network. A blue edge indicates a negative
correlation, and a red edge indicates a positive correlation.
