Dissecting nitrogen use efficiency in modern wheat, or who cares about nitrogen, and what can we do about it? Listen to Dr Malcolm Hawkesford’s talk which was given for the Inaugural AEV Richardson Lecture held on the 29th November, 2010.
In this Lecture, Dr Hawkesford will discuss targets for crop improvement including nutrient capture, photosynthetic capacity and canopy longevity, nutrient remobilization, yield and quality stability and the grain yield – grain protein conundrum and the prospects for improving grain protein deviation. The basic approach taken during his research involves the field scale screening of a wide diversity of wheat germplasm under different nutritional conditions, as well as exploiting the world’s oldest plant nutrition experiment, the Broadbalk experiment at Rothamsted. Such materials are used for de-convoluting traits contributing to nutrient use efficiency and crop performance, and utilising this variation for novel gene discovery approach via transcriptome and/or QTL analysis. Validation of candidate genes is undertaken via transgenic approaches.
