In leaf and sheath and detoxification of excess intracellular Fe (Figure 9). To confirm this hypothesis, the histological localization of ZmNAS1;1/1;two and ZmNAS3 had been studied employing in situ hybridization. The expression of ZmNAS1;1/1;2, two members in class I, was observedS0 S6 S12 S S24 S S48 S S96 S R0 R R6 R R12 R R24 R R48 R R96 RZhou et al.

In situ hybridization was performed on shoot and root sections of maize seedlings beneath Fe enough (upper panel) and deficient (decrease panel) circumstances with digoxigenin-labeled antisense or sense probes. Longitudinal sections of shoot apex (A, B, E and G), and transverse sections of root (C, D, F and H) had been hybridized. The expression of ZmNAS1;1/1;two was observed as purple staining in cortex and stele of Fe sufficient roots (C), epidermis, cortex and stele of Fe deficient roots (F), and leaf primordia of shoot apices (E) detected with antisense probes. No signal was observed in either handle sections with sense probes (B, D, G and H) or shoot apices of Fe sufficient seedlings detected with antisense probes (A).

In situ hybridization was performed on longitudinal sections of shoot (A, B and C) and transverse sections of leaf (E, D and F) employing digoxigenin-labeled antisense or sense probes. The hybridization signal was localized inside the leaf primordia (A), axillary meristem (B) and mesophyll cells (D and E), when no signal was detectable in handle sections hybridized with sense probes (C and F).Prednisone Arrow indicates the hybridization signals represented by purple staining.

ZmNAS3 accumulated in leaf primordia, axillary meristems and mesophyll cells, suggesting a part for class II genes in neighborhood translocation of Fe, in particular in building organs. Considering the fact that NA also chelate other metals, the expression of ZmNASs in response to Zn excess and Zn/Cu/Mn deficiency were examined. We found that the class I ZmNAS genes had been induced below Zn deficiency, whilst they were repressed below Zn excess, and Cu/Mn deficiency. These results recommended that the rising acc.
