| Abstract: | Cycloheximide (CHI) at 1 µg/liter delayed the loss ofchlorophyll from detached Anacharis canadensis leaflets senescingin the dark. Chloramphenicol (CAP) and streptomycin (SM) slightlyaccelerated the loss. CHI was effective even during the laterstages of senescence in preventing further loss of chlorophyll.Senescence proceeded normally upon return of the leaflets intowater. The need for cytoplasmic protein synthesis during chloroplastsenescence and the types of proteins involved are discussed. (Received March 26, 1976; ) |
