Metabolism of Separated Leaf Cells: II. Uptake and Incorporation of Protein and Ribonucleic Acid Precursors by Tobacco Cells 1

Francki, R. I. B.
RESUMO
Enzymatically separated tobacco leaf cells took up amino acids, uracil, and uridine from the incubation medium and incorporated them into proteins and RNA, respectively, at a linear rate for approximately 30 hours. Both uptake and incorporation were light-dependent, although cells prepared from preilluminated plants or preillumination of cells allowed some uptake and incorporation to occur in the dark. The light was necessary to satisfy a photosynthetic requirement, but could be replaced in part by ATP in the medium.
