Fig. 4. — Proteins from OG5 and OG16 do not accumulate in plasmodesmata. Confocal micrographs of N. benthamiana leaf epidermal cells producing fusions of moss (A, C) and Arabidopsis (B, D) members of OG5 and OG16. Each panel shows aniline blue-stained callose on the left, the protein–fluorescent protein fusion in the centre, and the overlay of the two images on the right. The positions of two plasmodesmata-associated callose deposits are indicated by arrows in each panel. Members of OG5, containing GDSL esterase/lipases, show an uneven intracellular localization suggestive of a membrane reticulum such as the ER. (A) shows Q4A3V3–GFP and (B) shows AtGELP–GFP (Q9LY84). Members of OG16, containing RNA-binding proteins, show nucleo-cytosolic localization characteristic of soluble proteins. Arrowheads indicate cytoplasmic strands (Cy). (C) shows PpGRP2–mCherry (Q8LPB1) and (D) shows AtGRP7–GFP (Q03250). Scale bars are 25 μm.
