Abstract

Transgenic oil sorghum reallocates photosynthate-carbon (C) into vegetative lipids, accumulating nonstructural lipids in both shoot and root tissues. Altered plant C allocation and root lipid accumulation may shift root exudate chemistry, belowground C inputs, and microbial nutrient demand throughout the soil profile. While aboveground productivity in high-oil sorghum is well-characterized, its belowground impacts on soil microbial enzyme activity and exchangeable cation dynamics, especially across soil horizons under drought stress remain unknown.

Project objective was to find out how transgenic high oil sorghum (Tx-HO1) influences CNP acquiring extracellular enzyme activities and soil exchangeable cation dynamics across soil horizons under drought and normal moisture conditions compared to wild-type sorghum (Tx-430).
