• Percentage of all gasoline sales blended with ethanol: 70%
--Source: www.mocorn.org
Missouri: Soy Biodiesel
• National rank in soybean production: 7th
• “Home” of soy biodiesel
• Operating soy biodiesel plants: 4
• Annual soy biodiesel production: 90 million

Plant Physiology
Genetic diversity in soybean under drought stress
Genetic diversity and
increased root proliferation
are associated with greater water uptake
from drying soil.

Genetics & Plant Breeding
Genetic mapping and engineering for total oil and oleic acid content
• Metabolite profiling to understand oil composition and accumulation in soybeans
• Genetic factors regulating fatty acid synthesis and total oil content
Oil Improvement
High seed oil content + high oleic acid = better “biodiesel”

Biotechnology for Bioenergy
Birchler Lab
Smallest mini-B chromosome
Red: TransgeneGreen: B repeat
“Minichromosomes”
Targeting B chromosomes
• Minichromosomes can serve as a platform for multiple transgenes.
• An extra chromosome would allow plants to be used as a factory for the production of multiple foreign proteins.
• Minichromosomes could also be used to add/modify whole biochemical pathways to plants.
