Abstrakt: Dark‐grown cells of mutant C‐2A' of Scenedesmus obliquus accumulate monovinyl‐and mainly divinyl‐protochlorophyllide (PChlide). Both PChlide‐forms are equally well photoconverted in vitro by the NADPH‐protochlorophyllide oxidoreductase of the light‐dependent greening mutant C‐2A’of Scenedesmus obliquus. The chlorophyllide (Chlide) resulting from this photoconversion in vivo has a predominantly monovinyl character. Only small traces of a transient Chlide‐form with divinyl fluorescence could be detected. [ABSTRACT FROM AUTHOR]
