Curved structure of chloroplast lamellae stacks—multivesicular structures and viral particles in vacuole in different leaf tissues of rbohF plants 3 (A,B) and 7 days (C,D) after TuMV inoculation examined under a TEM. (A) Curved thylakoids (double-headed arrow) in chloroplast (ch) of palisade mesophyll cell. (B) Multivesicular structures (“single membranes with tubules”) (MVB; *) in vacuole (v) and paramular bodies (PMBs; marked by diamond head arrow) in phloem apoplast area. CW—cell wall. (C) Virus particles (VPs; arrowhead) and multivesicular bodies (MVB; *) inside vacuole (v) of spongy mesophyll cell. ch—chloroplast. (D) Irregular structure (arrows) of the cell wall (CW) between spongy mesophyll cells. ch—chloroplast; v—vacuole.
