Figure 8. Zn and Cu efflux from barley chloroplasts is ATP dependent and inhibited by Thapsigargin.

Figure 8

Metal transport assay on purified chloroplasts showed significantly reduced A) Zn and B) Cu content after addition of Mg-ATP, suggesting Mg-ATP induced Zn and Cu export. After addition of Thapsigargin (Tg) Zn and Cu content was again increased. Values with the same letter between treatments are not significantly different (P>0.05). Data are the means ± SE (n = 5).
