The Influence of PPDK on Nitrogen Remobilisation in Wheat during Senescence

If you have a question about this talk, please contact Suzy Stoodley .

The market-value of wheat is hugely dependent on protein content of grain. Attempts to increase the protein content by fertiliser addition and breeding have been successful, but the underlying metabolic pathways remain undefined. A novel pathway has been proposed in which pyruvate,orthophosphate dikinase (PPDK) plays a crucial role in nitrogen remobilisation from leaves to seeds during senescence. I am trying to elucidate the N remobilisation pathway and investigating the role of PPDK in wheat by characterising it in wild-type wheat as well as generating and phenotyping lines that over-express PPDK during senescence.
