Thin section of a wildtype chloroplast of Arabidopsis thaliana showing the characteristic distribution of thylakoids membranes in stacked grana (black arrow) and unstacked stromal regions (white arrow...

Thin section of a chloroplast of Arabidopsis thaliana lacking the FZL protein, a member of the dynamin superfamily of proteins. FZL is related to FZO, a protein that mediates fusion between mitochondr...

Wheat seeds were germinated and grown for 6 days in the dark, greened at high light intensity for 4 days, then prepared for thin section electron microscopy. This chloroplast from a wild-type plant sh...

CD3 mutant wheat (deficient in chlorophyll b) was germinated and grown for 6 days in the dark, greened at low light intensity for 4 days, then prepared for thin section electron microscopy. Under thes...

Transmission EM of cotyledon of the double knockout oep16.1/16.4 of Arabidopsis thaliana grown in the dark and grown under a normal day/night light regime. Characteristic wildtype thylakoids are seen....

Transmission EM of cotyledons of wildtype Arabidopsis thaliana grown under a normal day/night light regime show the typical chloroplasts with thylakoid membranes organized as stacked grana and non-sta...

Transmission EM of cotyledons of the double knockout oep16.1/16.4 of Arabidopsis thaliana grown in the dark and then exposed to light for 16 hr. The development of characteristic wildtype thylakoids ...
