The Grass Genetics group takes advantage of the knowledge of grass genetics to engineer root system architecture, improve biomass performance, and assess microbial associations of sorghum.
Projects
- Engineer grasses for nitrogen use efficiency
- Engineer sorghum for enhanced root growth, biomass and assess plant-microbe associations
- Create and characterize sorghum genetic variation
