1) Use and explore beneficial bacterial endophytes to boost growth of bioenergy crops, such as switchgrass, hybrid poplar, Miscanthus x giganteus, and Jerusalem artichoke to develop a low input, sustainable bioenergy feedstock production system in collaboration with Dr. Barry Flinn.
2) Establish and optimize switchgrass tissue culture and transformation system to genetically engineer switchgrass for biomass yield improvement and stress tolerance enhancement. We have transformed 8 genes into switchgrass. These genes are involved in floral development, leaf senescence, and stress tolerance.
3) Develop micropropagation protocol to produce large number and high quality Miscanthus x giganteus plants for large scale bioenergy feedstock production. A high efficient micropropagation system has been established. The technique has been applied for a US patent and moved to our commercial lab.
4) Screen different germplasms of Jerusalem artichoke to find out cultivars suitable for Southside Virginia area and establish tissue culture and transformation protocols for quick genetic engineering Jerusalem artichoke to breed elite cultivars for feedstock production in local region.
