Expressions of RLRH1 and RLRH2 in protein storage vacuoles (PSVs) in the aleurone and endosperm cells of wild-type (WT) transgenic rice seeds. a, d, g, and j PSVs in WT cells labeled by gene-specific antibodies; b, e PSVs in cells of pA3. c, f PSVs in cells of pA4. h, k PSVs in cells of pB3. i, l PSVs in cells of pB4. Immunogold particles with 6 nm diameter were used. White arrows indicated immunolabeled candidate proteins. Bar, 500 nm. The insets with asterisks are enlargements of the boxed areas
