Transmission Electron Microscopy Immunolocalization of GS in Maize Leaf Sections at VS.

(A) to (C) Localization of GS in parenchyma cells of the wild type (A). Magnification of the zone containing MC (B) and BSC (C).

(D) to (F) Localization of GS in parenchyma cells of the gln1-3 gln1-4 mutant (D). Magnification of the zone containing an MC (E) and a BSC (F).

(G) and (H) Localization of GS in MCs of the gln1-3 mutant (G) and in the BSC of the gln1-4 mutant (H).

(I) and (J) Localization of GS in PCC in the wild type (I) and in the gln1-3 gln1-4 mutant (J).

(K) Control section in the wild type treated with preimmune serum.

cy, cytosol; p, plastid; m, mitochondrion; s, starch granules. Arrows indicate the presence of GS protein.

Bars = 1 μm in (A) and (C) and 0.5 μm in (B) and (D) to (K).
