Figure 4

Autoradiography of static 74As in fronds of P. vittata supplied with As for 168 h. (a) Fed with 0.2 μM AsV. (b) Fed with 20 μM AsV. (c) Fed with 200 μM AsV. (d) Fed with 2000 μM AsV. All experiments included 2 kBq of 74As-labeled AsV. Fiddlehead and apical pinna of young fronds (brown arrow), midrib (green arrow), rachis (yellow arrow) sporangia (blue arrow) and the gray margin pinna showing necrotic symptoms (red arrow).
