Figure 1



Ionome of rice and wheat grain in their cultivars released along the succeeding decades. Left and right vertical axis represents mineral concentration in wheat and rice grain, respectively. Horizontal axis represents decades of cultivar release for rice and wheat. Black triangles and dots represent projected change in ionome of rice and wheat grain along succeeding decades up to 2040. All units are in mg kg−1. Data are mean (n = 6). Vertical bars indicate standard error of mean. Asterisks indicate significant differences between the observed means of the decades for the cultivars of rice and wheat released up to 2000s and 2010s, respectively (*P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001).
