The principal co-ordinates analysis (PCoA) analysis of bacterial (A) and fungal (B) communities in various saline-alkaline soils at the ASV level. The values are the means of three replicates, error bars represent standard errors (L: n = 10; M: n = 8; H: n = 6). ** represents p < 0.01 level significant, and * represents p < 0.05 level significant. The L, M, and H treatments represent EC of 0–1, 1–2, and > 2 ms/cm, respectively.
