The immunodetection of H4K5ac in ‘matured’ (A–D), ‘dry’ (E–H) and ‘germinating’ (I–L) Brachypodium embryos.

Cross sections through the scutellum (A, I), the scutellum, coleoptile and leaf primordia (E), the SAM with leaf primordia (B, F, J), the RAM (C, G, K), the distal part of RAM, the root cap and coleorhiza (D, H) and the coleorhiza (L). Bar: 50 µm. Enlargements of selected cross sections are provided (Figure S1).
