 Title    Chloroplast Biogenesis, Its Inhibition and Modification by New Herbicide Compounds  
 Abstract    Biogenesis and developm ent o f chloroplasts are sum m arized in the light o f new findings; the interactions o f different groups o f photosynthetic herbicides with chloroplast developm ent are indicated. The effect o f two new active ingredients, m evin olin* and sethoxydim **, on chloroplast m odification and biogenesis are described. M evinolin blocks the cytoplasm ic HMG-CoA reductase and sterol accum ulation and m odifies chloroplast differentiation via the formation o f a sun-type chloroplast. Sethoxydim inhibits leaf growth in grasses and gram ineous crop plants and strongly affects chloroplast biogenesis and differentiation at all stages o f development from proplastids via prochloroplasts to young and mature chloroplasts. This applies to thylakoid formation and m ultiplication, grana form ation as well as chloroplast division and chlorophyll and carotenoid accumulation. The chlorophyll fluorescence induction kinetics (Kautsky effect) indicate that photosynthesis is not affected. At higher doses sethoxydim stops all growth responses o f maize plants and induces the accum ulation o f anthocyanins.
