An efficient method of selecting photoautotrophic cells from cultured heterogeneous cells

A new and efficient method was demonstrated for the establishmentof photoautotrophic cultures of plant cells. Leaf segments ofAtropa belladonna, Datura stramonium and Hyoscyamus niger wereinoculated on sugar-free Linsmaier-Skoog agar medium then aeratedwith 1% CO₂ enriched air under 3,000 to 5,000 lux of illumination.Under these regulated conditions we could select photoautotrophicgreen cells efficiently, and these cells subsequently have grownwell under photoautotrophic conditions. ¹Department of Horticulture and Agriculture, Faculty of Agriculture,Kobe University, Kobe 657, Japan (Received June 12, 1980; )
