  abstract = {{P}iliostigma reticulatum is a native woody shrub found in cropped fields in the {S}ahel and has been shown to increase crop productivity and soil quality. {F}requently occurring drying and rewetting cycles ({DRW}) may alter the soil quality beneath these shrubs. {W}e investigated the effect of {DRW} cycles on microbial community in soil beneath and outside the {P}. reticulatum canopy and the roles of this shrub in the adaptation of the microbial community to abiotic stress. {S}oils were incubated in a climate controlled chamber for 45 days, after exposure to 10 consecutive days of {DRW} cycles at 75% of water holding capacity ({WHC}). {B}asal respiration, b{\^e}ta-glucosidase activity, microbial biomass carbon ({MB} {C} ), and available nitrogen ( {NH}+4 ; 3{NO}-3 ) were measured at 2, 30, and 45 days after soil exposed to the {DRW} cycles. {MB} {C} increased significantly two days after the {DRW} cycles and was greater for soil beneath the shrub canopy compared with soil outside the shrub canopy. {PCA} analysis based on basal respiration, microbial biomass carbon, available nitrogen, and b{\^e}ta-{G}lucosidase activity resulted in a tight clustering in the beneath shrub soil samples. {S}oils incubated for more than 30 days after {DRW} cycles had higher available nitrogen content than soils incubated for less than 30 days. {S}oil from beneath the shrub canopy significantly improved soil resilience based on b{\^e}ta-glucosidase activity. {S}oil from beneath the shrub canopy also had higher nutrient levels and greater microbial activity even when subjected to {DRW} cycles, potentially improving the ability of crops to withstand in-season drought when they are adjacent to shrubs. {T}he work should bring our scientific community into a more comprehensive assessment of potential effects of a crop-shrub intercropping that may allow for increased crop yields in semi-arid ecosystems under drought conditions.},
