Figure 3. Subcellular localization of PAL in endosperm cells of transgenic rice seeds.

Figure 3

(A–B) Immunogold labeling of WT (A) and SP (B) endosperm cells using anti-PAL antibody. Gold particles were indicated by arrows. (C–D) Immunogold labeling of SA endosperm cells using anti-PAL antibody (C) and with anti-ELP antibody (D). (E) Novel irregular protein bodies, iPBs, as indicated by *, were formed in endosperm cells of SA seeds. (F) The iPBs at the protein body-ER site were also observed. Arrows indicated the labeled gold particles while arrowheads ribosomes on rough ER membrane. PSV, protein storage vacuoles; CW, cell wall; PB-I, type I protein bodies; and bar, 500 nm.
