Abstract
For the purposes of reducing fertilizer inputs in arable farming, there is a need to develop reliable and sensitive techniques for determining the nutrient status of crop plants in the field. In this proposal we will examine the feasibility of generating transgenic plants that are self-reporting for their nutrient status. We will use RNA fingerprinting to identify gene transcripts in tobacco leaves which accumulate specifically in response to individual nutrient deficiencies. The promoters of several of the corresponding genes will be isolated and fused to the luciferase reporter gene and re-introduced into tobacco. Luciferase activity in the transgenic lines grown under different nutrient regimes will be assayed to establish the suitability of the promoters for reporting nutrient stress.
