Table 1. Functional diversity indices of soil microbial communities in soils under four treatments (non-infected Mikania, and low-, medium-, and high-level infected Mikania by Cuscuta). Different letters within a column indicate significant difference between treatments (p < 0.05).

Treatments	Shannon-Wiener diversity index	Evenness diversity index	Simpson's diversity index
Control	3.187 ± 0.010a	0.934 ± 0.003a	21.723 ± 0.200a
Low-level infection	3.057 ± 0.173b	0.905 ± 0.009b	18.160 ± 0.266b
Medium-level infection	3.115 ± 0.012b	0.910 ± 0.003b	19.526 ± 0.204b
High-level infection	2.966 ± 0.022c	0.878 ± 0.007c	15.368 ± 0.312c
