Abstract

Nutrient utilization in wheat will be investigated using the 160 year old Broadbalk experiment at Rothamsted and a field trial with varieties selected for contrasting source-sink resource patterns (high protein, high starch, large and small leaf varieties, fast developing and a non-dwarfed variety). Trancriptomic and metabolomic data will be generated and combined to generate a co-response network. Objectives: 1. To identify genes and metabolic processes involved in nutrient remobilization which may be candidates for variety improvement. 2. To test the hypothesis that the processes involved in resource (N and S) mobilization during wheat grain filling can be elucidated by the integrated analysis of transcript and metabolite data sets from varieties with contrasting developmental profiles grown under a range of nutritional inputs. 3. To investigate the assumption that the processes operating preferentially at limiting resource availability, are the major contributors to the efficient use of those resources, particularly leaf to seed remobilization. 4. To use transcriptome and metabolite profiling to identify and give insights on candidate regulators of the system. 5. To examine how remobilisation processes are affected by nutrition. 6. To examine how genotypes with contrasting developmental profiles vary in their ability to remobilise resources from leaf to grain7. To provide a description (publicly available) of the transcriptome and metabolome of wheat leaves during grain filling.
