Model of More Developed Grana Visible during the Third Day of Day/Night Growth (Stage 3.3).

(A) Middle layer of the tomography stack.

(B) Magnification of the modeled region (green).

(C) and (D) Surface model embedded in the selected TEM layer viewed from two different angles.

(E) to (I) Surface visualization from five different angles showing a very regular parallel arrangement of grana thylakoid layers (light navy) associated with six stroma thylakoids (navy).

(F) Splitting of the bottom stroma thylakoid (star).

(G) Stroma thylakoids are connected with two neighboring grana thylakoids at an angle of ∼18°.

(H) and (I) A particular stroma thylakoid is split in two and connected with the adjacent grana thylakoid (H) and with the next grana thylakoid in another slice (I), as shown inside the small white rectangles.
