Abstract
When Euglena cells were irradiated only in the nuclear region with a UV microbeam apparatus, no bleached progeny were observed. Irradiation of the entire cell or only the cytoplasm caused bleaching of the progeny of the irradiated cells. It is concluded that the UV-sensitive factors which are concerned with the differentiation of the proplastids to chloroplasts are localized in the cytoplasm and not in the nucleus.
