CD3 mutant wheat (deficient in chlorophyll b) was germinated and grown for 6 days in the dark, greened at high light intensity in the presence of chloramphenicol for 4 days, thylakoids prepared, plunge-frozen, and freeze-fracture replicas obtained and examined by transmission electron microscopy. This region shows the characteristic particle size and distribution found on the EFs and PFs membrane faces of stacked thylakoid membranes. This set of grouped images, which also shows thin sections, includes images of wild-type wheat.
