Figure 3. HvHMA1 is primarily expressed in leaves and grains.

Figure 3

A) expression of HvHMA1 in leaf, stem, root, and grain tissues during grain filling. HvHMA1 expression is high in leaves and grains, while the expression is lower in stems and roots. In grains during filling HvHMA1 expression is high in the grain rest (containing the pericarp) and highest in the endosperm, in particular at 25 days after pollination (DAP). B) Expression of HvHMA1 in whole grains at different days after germination (DAG). The increasing expression during germination is likely caused by up-regulation in shoot expression, which is evident in C) where expression of HvHMA1 in isolated shoots (black) is up-regulated, while the expression stays low in roots (grey) from germinating seeds. Values with the same letter between treatments and within the same time are not significantly different (P>0.05). Data are the means ± SE (n = 3–4).
