Abstract

Details should only be considered in the context of PU information. Plant nutrition is a complex web of interacting pathways. Strategies currently under consideration which utilise genetic modification to improve uptake and utilisation of one nutrient, for example nitrate, must consider the implications on other aspects of plant metabolism, including the S-assimilatory pathway. Relieving one bottleneck will result in other metabolic bottlenecks. This project will: 1.Analyse components of the S and N assimilatory pathways. 2.Clone genes involved in the above and produce transgenic plants manipulating components of the pathways. 3.Examine the interactions of the S and N assimilatory pathways. 4.Determine the regulatory mechanisms involved. 5.Apply this research to agricultural problems, specifically relating to efficient nutrient utilization and diagnosis of crop nutrition to aid fertilizer recommendation. Attention will be paid to technology transfer from laboratory analysis to realistic field based assessment.
