Our approach will be to 1) evaluate mycorrhizal dependency of modified sorghum cultivars in controlled greenhouse studies; 2) determine consequence of reductions in dependency on the symbiosis by assessing: drought tolerance, grain quality (C:N:P) and quantity, biomass production, and root morphology (e.g. root length production) of selected cultivars; 3) assess drought tolerance, tissue quality, and biomass production of selected cultivars grown with and without the fungal symbiont, under high- and low-input fertilization; 4) conduct biochemical characterization of sorghum starch and protein; and 5) evaluate end-use grain quality from each cultivar.
