Phosphorylation patterns were visualized by autoradiography

Root tips were subsequently visualized using confocal microscopy at the same magnification for each. Al treatment results in substantial increases in both cell and nuclear size for als3-1 roots, which is consistent with terminal differentiation in conjunction with endore duplication . In contrast, atr-4;als3-1, alt2-1;als3-1, and sog1- 7;als3-1 roots did not show the dramatic Al-dependent increases …
