FEEDSTOCK GENOMICS AND TRANSGENICS FOR CELLULOSIC ETHANOL
Convener: Fredy Altpeter, University of Florida-IFAS
|8:00 am – 10:00 pm
Plant biomass is expected to play a major role in the substitution of fossil fuels. To date, most ethanol is derived from sugar or starch crops by fermentation. The ability to produce ethanol from ligno-cellulosic biomass from perennial, low-input, non-food crops will be key in maximizing the environmental and economical benefits of biofuels. Cell wall recalcitrance has been identified as a major bottleneck for the economic production of ethanol from lignocellulosic plant biomass, resulting in low yield and high cost of the pretreatment/hydrolysis process. Speakers in this session will highlight recent advances in genomics and transgenic approaches to improve biofuel production from different biomass crops.

ADVANCES IN ENHANCING TRANSGENE EXPRESSION LEVELS IN PLANTS USING NUCLEAR OR TRANSPLASTOMIC APPROACHES
Convener: Kasi Azhakanandam, Syngenta Biotechnology, Inc.
|10:30 am – 12:30 pm
Since the production of the first transgenic plants more than a quarter century ago, remarkable progress has been made in terms of expressing various transgenes for different purposes. However, demands for expressing heterologous proteins at high levels in different plants/crops are ever increasing as plants continue to gain recognition as an alternative and competitive expression system. Consequently, novel approaches have been developed based on both nuclear and plastid transformation processes. In this session, we have exciting talks lined up to highlight unconventional ways to enhance recombinant protein expression levels in plants.

HIGHLIGHTS IN PLANT BIOTECHNOLOGY IN THE SOUTHEAST
Convener: Peggy Ozias-Akins, University of Georgia
|10:30 am – 12:30 pm
The annual Society for In Vitro Biology meeting rotates to a different region of the country each year. With the 2009 meeting being held in Charleston, SC, a venue that is relatively easy to reach from the Atlantic coast states of the southeast, four of these states will participate in the session on highlights of plant biotechnology in the southeast. Plant biotechnology industries, particularly those with strong agricultural divisions, are well represented in the southeast and rely on state universities to provide a part of their trained workforce. Faculty from four research universities will give brief overviews of biotechnology expertise and opportunities at their respective institutions, then will provide specific examples of their own biotechnology-related research.
