Abstract:
Farming wheat in Europe requires a large input of chemicals to realise maximum yield. This is now a heavy burden on the farming industry as the EU implements its CAP reforms which will reduce cereal prices. We propose to develop wheat with enhanced inherent nitrogen use which will require less fertiliser input thus cut the cost of production and safeguard the environment from excessive nitrate pollution and greenhouse gas emissions, in line with EU directives. Partner one has developed wheat with improved nitrogen use by over-expressing the enzyme glutamine synthetase (GS). We will combine cereal transformation with quantitative genetics and nitrogen metabolism to develop new wheat genotypes with improved fertiliser-use efficiency. This will demonstrate that genetic manipulation of plants can be environmentally safe, economically useful and important for solving difficult agronomic problems.

Objectives:
The farming industry needs productive wheat with improved efficiency of nitrogen uptake and utilisation. We propose a two-track approach to develop new genotypes with improved nitrogen-use efficiency: 1) Use molecular genetics to develop a screen for N use in breeding programmes. QTL analysis on established double haploid lines will be done to establish the validity of using GS as a biochemical marker in selecting for N-use efficiency. We will locate the wheat GS gene(s) to an available marker saturated map of wheat. 2) Develop new wheat genotypes with enhanced N use by cereal transformation on élite and double haploid mapped lines to over-express glutamine synthetase in shoot. We will study the transformed wheat in the field to select lines with enhanced N-fertiliser-use efficiency. We will evaluate the economics of new wheat genotypes in integrated farming systems.
