Introduction For low-fertile and degraded soils of sub-Saharan Africa, nitrogen (N) is often the most growth-limiting factor restricting crop yields. The often-suggested exploitation advantageous rhizosphere traits such as enzyme secretion and/or symbiosis with arbuscular mycorrhizal fungi (AMF) remains to be validated a potential strategy overcome N limitation, especially when deficiency co-occurs further abiotic stresses water scarcity. Methods Three sorghum genotypes were cultivated in soil mesocosms root-exclusion compartment, where only AMF could scavenge for nutrients under drought optimal conditions. Plant carbon (C) investment into uptake tracked by 15 application coupled 13 CO 2 labeling Results Under drought, mineral from compartment increased 4–12 times compared well-watered In addition, stress enhanced below-ground allocation recently assimilated C microbial biomass. Drought reduced enzymatic (Vmax) chitinase while increasing leucine aminopeptidase (LAP) activity. This suggests that acquisition via protein mineralization was relatively chitin following moisture limitation. LAP substrate affinity (Km) genotype-specific shifts systems observed. Conclusion Our findings suggest activated its associated microbiome. not led shift enzyme-driven distinct organic sources but also induced strong increase AMF-based mycosphere. trait plasticity response may harnessed stabilize food production increasingly negative impacts droughts due climate change.
