Abstract

The quantities of chloroplast proteins and chlorophyll were lower in oat plants treated 6 days with 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) than in the controls. Radioactive amino acid incorporation into chloroplasts indicated that the reduced levels of protein resulted from reduced synthesis. Glucose improved the amino acid incorporation in the treated tissue, but still the rate was reduced markedly by the simazine treatment. An effect of simazine even in darkness on amino acid incorporation into chloroplasts was suggested by the data. Total ribonucleic acid (RNA) content and synthesis as measured by incorporation of p32 were altered by simazine treatments.
