Ion content of wild-type and eca1-1 mutant plants

μg/g dry wt−1
eca1-1 6,9132952,644253200
eca1-1 6,1701,8302,203275202

Five-day seedlings of wild-type plant (ECA1) and mutant (eca1-1) were grown in liquid medium with 0.5× Murashige and Skoog alone (−Mn) or supplemented with 0.5 mM Mn2+(+Mn) for 2 weeks. Ion content of whole plants was analyzed by ICP emission spectrometry. Average of two to three experiments.
