A desired (single) gene of interest Combines multiple genes Introduce foreign genes simultaneously Rapidly generate plants with improved Mendelian Genetics (same species) varieties Enhance market value of the plant Challenge: Jatropha is susceptible to cold. Transformation with CBF3 can make it cold resistant. 1 Proof of concept for cold and drought tolerance induced by CBF3 demonstrated in Petunia and corn (Sairam et al, 2008) Plant 1: After exposure to -6° C ( 22°F) Plant 2: 2 Watered to saturation No watering for 15 days 24 hours after watering CBF NT Sairam R.V., Al-Abed, D., Johnson, J., Muzynski, M., Raab, M., Reddy, T.V. and Goldman, S.L.

Summary & Future Research SUMMARY .GUS and GFP expression was positive in PCR results. FUTURE RESEARCH .To perform molecular analysis for CBF3 .Develop Jatropha to be resistant to other abiotic and biotic stress. Industrial use of Jatropha Oil On January 7, 2009 Continental Airlines successfully completed a test flight from Houston, Texas using a 50/50 mixture of algae/Jatropha oil-derived biofuel & http://phx.corporate-ir.net/phoenix.zhtml? traditional Jet fuel in one of the 2 engines. c=85779&p=irol-newsArticle&ID=1241576 Acknowledgements • National Science Foundation (NSF) for their fellowship • The Pennsylvania State- Harrisburg • Ben Tabatabai (Mentor, tissue culture, transformation and procedures), Deepkamal Karelia(Biolistic Transformation)Mathew Ritzel (Molecular Analysis) • Dr. Puthiyaparambil Josekutty, Dr. Sairam Rudrabhatla • NSF-REU staff and colleagues Work Cited Continental Airlines Flight Demonstrates Use of Sustainable Biofuels as Energy Source for Jet Travelhttp://phx.corporate-ir.net/phoenix.zhtml?c=85779&p=irol-newsArticle&ID=1241576 Plant Transformation: Problems and strategies for Practical Application.
