Some observations on chlorophyll(ide) synthesis by isolated etioplasts.

Abstract

1. A modified procedure for the isolation of etioplasts from dark-grown barley is described and the regeneration of phototransformable protchlorophyll(ide) was demonstrated in the isolated plastids. 2. On exposure of the etioplasts to a long-term flash illumination, chlorophyll(ide) synthesis from a precursor pool, which includes all the protochlorophyllide, was demonstrated. 3. Added delta-aminolaevulinic acid failed to be significantly incorporated into chlorophyll(ide) in the etioplasts despite its extensive incorporation into porphyrin precursors of chlorophyll and haem compounds. The findings are discussed in terms of the inability of etioplasts to carry out the metal-insertion step in chlorophyll synthesis. 4. An elevated chlorophyll(ide) concentration was attained in the etioplasts by increasing the size of the utilizable precursor pool by pre-feeding whole plants with delta-aminolaevulinic acid, isolating the etioplasts and subjecting them to the flash illumination.
