This Small Business Technology Transfer Research (STTR) Phase 1 Project proposes to develop transgenic maize (Zea mays L.) with increased tolerance to heat stress. It has recently discovered that a gene encoding the maize chloroplast protein synthesis elongation factor, EF-Tu, plays a role in the development of heat tolerance. EF-Tu protects other proteins from heat-induced inactivation and aggregation. The overall goal of this project is to genetically engineer maize that overproduces EF-Tu under high temperature conditions and to exploit the protective role that EF-Tu plays in heat tolerance. The key objectives of the Phase 1 research include (a) the creation of EF-Tu transgenic maize protoplasts, Arabidopsis and maize whole-plants and (b) the assessment of their heat tolerance in the laboratory. The results of the Phase 1 project will lay the groundwork for the follow-on Phase 2 and Phase 3 projects. They will include the testing the performance of EF-Tu transgenic maize in the field (Phase 2) and its commercialization (Phase 3).
