The Great Basin Native Plant Project is a cooperative project lead by the Bureau of Land Management (BLM) Plant Conservation Program and the United States Forest Service (USFS), Rocky Mountain Research Station that was initiated to provide information that will be useful to managers when making decisions about the selection of genetically appropriate materials and technologies for vegetation restoration. The Project is supported by the USDI Bureau of Land Management, Plant Conservation Program and administered by the USFS Rocky Mountain Research Station’s Grassland, Shrubland and Desert Ecosystem Research Program. Research priorities are to: . Increase the variety of native plant materials available for restoration in the Great Basin. Provide an understanding of species variability and potential response to climate change to improve seed transfer guidelines. Develop seeding technology and equipment for successful reestablishment of native plant communities. Transfer research results to land managers, private sector seed growers, and restoration contractors. We thank our many collaborators for their dedication and their institutions for their in-kind contributions. The wide array of expertise represented by this group has made it possible to address the many challenges involved with this endeavor. We especially thank Alexis Malcomb for the many hours she spent carefully editing and compiling this report and other outreach materials and Jessica Irwin for help in editing, as well as Corey Gucker for help in managing our financial reporting. Special thanks also to our resident technicians and volunteers: Nancy Shaw, Matt Fisk, Jameson Rigg, and Kristof Bihari for managing our field and laboratory research.

Big-eyed bugs (Geocoris spp. Fallen,´ Hemiptera: Lygaeidae) are ubiquitous, omnivorous insect predators whose plant feeding behavior raises the question of whether they benefit or harm plants. However, several studies have investigated both the potential of Geocoris spp. to serve as biological control agents in agriculture and their importance as agents of plant indirect defense in nature. These studies have demonstrated that Geocoris spp. effectively reduce herbivore populations and increase plant yield. Previous work has also indicated that Geocoris spp. respond to visual and olfactory cues when foraging and choosing their prey and that associative learning of prey and plant cues informs their foraging strategies. For these reasons, Geocoris spp. have become models for the study of tritrophic plant-herbivore-predator interactions.

The involvement of TD in development was determined by characterizing antisense TD (asTD) transgenic plants that had short roots; delayed opening of cotyledons, and leaf and flower senescence; and retarded growth. I demonstrated that the phenotypes of asTD transgenic plants could be partially recovered by adding α-keto butyrate, which is the first product of TD activity, Ile, or jasmonic acid-Ile conjugate.
