摘要： Mesosulfuron-methyl is a widely used herbicide in wheat fields. We previously reported that mesosulfuronmethyl alters the bacterial/fungal community structure in experimental indoor microcosms, ultimately affecting NO3--N and NH4+-N contents in soil nitrogen (N) cycling. However, how mesosulfuron-methyl application alter soil N cycling by changing microbial community assembly is unknown. Here, we designed an outdoor experiment comprising 2-month periods to investigate changes in soil N-cycle functional genes and structural shifts in the microbial community assembly in response to mesosulfuron-methyl applied at 11.25 and 112.5 g a.i. hm-2. Results showed that high mesosulfuron-methyl input significantly decreased AOA amoA and nirK
