To test the feasibility of improving photosynthetic thermotolerance, we would like to launch an extensive transgenic project with the oilseed crop, camelina. In this project we would express both regulated and non-regulated forms of modified activase behind activase and heat-inducible promoters in a background of wild type activase. Transgenic camelina plants harboring the various constructs will be evaluated under natural conditions of light under control and elevated temperatures in the greenhouse and plants with superior performance will be tested in the field. Successful completion of the three objectives with camelina and a fourth objective with tobacco will resolve outstanding questions about the feasibility of improving plant thermotolerance by introducing an improved activase and answer several basic mechanistic questions about the regulation of Rubisco in plants.
