- Determine the effects of six newly identified brown midrib (bmr) mutants on lignin synthesis and the monolignol biosynthetic pathway.
- Develop transgenic lines over-expressing genes in monolignol biosynthesis to determine their impact on lignin content and composition.
- Identify strategies for increasing the sugar content of sweet sorghum juice and improve its biomass composition for thermal conversion.
- Determine the effects of brown midrib (low lignin) mutations alone or in combination on bioenergy conversion via saccharification and fermentation.
- Develop sorghum lines with novel lignin composition and determine the effects on bioenergy conversion.
- Develop sweet sorghum germplasm incorporating bmr6 and bmr12 to reduce lignin and determine the effects of these alleles on end-use quality.
