Element accumulation in young leaf relative to flag leaf of 54 barley introgression lines.

<p>Shown are Log₂ ratios of element concentrations in the young leaf <i>versus</i> the flag leaf for (A) Cd, (B) Zn, (C) Fe, (D) Cu, (E) Mn, (F) Mg, and (G) Ca. Each bar represents the least-square mean of one IL (<i>n</i> = 3 to 7), with ILs sorted by ascending grain Cd concentration from left to right. Dashed horizontal lines indicate the position of the least-square mean of the recurrent parent Scarlett (<i>n</i> = 144). Measurements were from the same experiment as shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153392#pone.0153392.g001" target="_blank">Fig 1</a>.
