Fig. 8. — Chloroplast ultrastructure of mesophyll and bundle sheath cells from C₃F. pringlei and C₄F. bidentis. Transmission electron microscopy was used to investigate chloroplast ultrastructure. (A, B) Bundle sheath chloroplasts from C₃Flaveria pringlei and C₄Flaveria bidentis. (C, D) Mesophyll chloroplasts from C₃F. pringlei and C₄F. bidentis. Little granal stacking was seen in bundle sheath chloroplasts from F. bidentis (B) whereas it could be observed in C₃ bundle sheath and in all mesophyll chloroplasts. Insets show a close-up of thylakoids, with white arrowheads indicating thylakoid stacks (A, C, D) or the lack of extensive stacking (B). Scale bars represent 500 nm.
