Fig. 7

Genus-level composition (a, c, e) and linear discriminant analysis (LDA) effect size analysis (b, d, f) of bacterial communities based on denitrification functional genes under different types of salt and alkali stresses in a calcareous desert soil. Relative abundance (%) of genera in a nirK, c nirS, and e nosZ communities. LDA scores of dominant taxa in b nirK, d nirS, and f nosZ communities. CK, control treatment without salt or alkali stress; CS, NaCl stress treatment; SS, Na2SO4 stress treatment; AS, Na2CO3 + NaHCO3 stress treatment
