Plastidal differentiation in Acetabularia studied by fluorescence emission at 77° K. Examination of the 77° K fluorescence emission spectra provides a good criterion for distinguishing chloroplasts of the apical from those of the basal region of the stalk of Acetabularia cells at stage 4. Extraction increases the differences between the emission spectra of apical and basal chloroplasts. By using the 77° K fluorescence emission spectra technique, it is possible to show the differentiation of the plastids and to follow it during the regeneration of anucleate and nucleate fragments. © 1975.
