Über die osmiophilen globulären Lipideinschlüsse der Chloroplasten

Abstract

The electromicroscopical structure and quinone composition of the osmiophilic, globular, lipiderich plastid inclusions were investigated in several plants. The localisation of the osmiophilic globuli in the plastid stromaand their behaviour toward fixation agents are described. The isolated globuli – here termed plastoglobuli – contain high amounts of lipophilic chloroplasts quinones and apparently no chlorophylls or carotenoid. There existconsiderable differences in the relative quinone concentrations of chloroplasts and isolatedplastoglobuli. The possible function of plastoglobuli is discussed. © 1966, IEEE.
