Peripheral reticulum in chloroplasts of plants differing in CO2 fixation pathways and photorespiration

The development of peripheral reticulum (PR) in chloroplasts varies in C3 and C4 plants. In general, PR is more extensive in C4 plants, but PR is also seen in the chloroplasts of some C3 plants. Within some C4 plants, PR is seen in the bundle sheath cells which predominantly use the C3 pathway. Thus...

Summary:The development of peripheral reticulum (PR) in chloroplasts varies in C3 and C4 plants. In general, PR is more extensive in C4 plants, but PR is also seen in the chloroplasts of some C3 plants. Within some C4 plants, PR is seen in the bundle sheath cells which predominantly use the C3 pathway. Thus, PR is not associated directly with the presence of the C4 pathway on a cellular basis. Its predominance in C4 plants must be related to some characteristic other than the method of CO2 fixation. Ultrastructural evidence suggests that PR is associated with the rapid transfer of substances into and out of chloroplasts and from mesophyll to bundle sheath cells.
