Changes in grain dry mass, total quantity of nitrogen (Ntot) in the grain and grain protein concentration during grain development. SPA null segregant (NS, circles) and RNAi (RNAi, triangles) lines of bread wheat were grown in the greenhouse with low (N−, open symbols) and high (N+ , closed symbols) nitrogen supply. DM, dry mass. Data are means ± 1 s.e. for n = 4 independent replicates.
