Transmission microscopy electromicrograph in the mesocarp and placental region of Pogoniopsis shenckii. A Overview of fruit cells with high cytoplasmic content. B Detail of the dense cytoplasm. C Vesicles concentrated in the cytoplasm. D Vesicles scattered in the cell vacuole. E Dense cytoplasm, release of secretion near the cell wall. F-L Fungal hyphae. F Fungal hyphae in the cell of the placental region. G Fungal hyphae in the mesocarp cells. H Fungal hyphae penetrating the cell wall. I-J Detail of the fungal hyphae in the mesocarp cells. K Fungal hyphae in the mesocarp cells of the ripe fruit. L Fungal hyphae in the collapsed cells of the ripe fruit. c = cytoplasm; fh = fungal hyphae; cw = cell wall; v = vesicles.
