Summary Leaves of Nicotiana rustica contain a 0.5 × 106 molecular weight RNA which is rapidly labeled during incubation of the leaves with 32Pi. This RNA is located only in the chloroplast fraction of the cell homogenate and bound to the membranes o

Summary Chloroplast rRNA is synthesized in all green leaves of Nicotiana rustica independent of their age and independent of the period of chloroplast differentiation. The chloroplast rRNA content of the leaves decreases during ageing. The RNA-polyme

The effects of a cytokinin (N(6)-benzyladenine, BA) and light on plastogenesis have been studied in detached Cucurbita cotyledons using the key enzyme of photosynthetic CO2 fixation, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCase), as an e

The 80 000 x g supernatants of spinach leaf homogenates contain polypeptides that are immunologically related to the ββ′, α and σ subunits of Escherichia coli RNA polymerase. The σ-like (90 kDa and 33 kDa) and α-like (38 kDa) polypeptides are

Using solid-phase `Sandwich' immunoassays we studied DNA-dependent RNA polymerase of spinach chloroplasts with regard to (i) polypeptide composition of the multimeric enzyme; (ii) immunological cross-reaction with Escherichia coli RNA polymerase; (ii

Summary In leaves of Nicotiana rustica the formation of ribosomal RNA is inhibited by FU at concentrations higher than 90 μg FU per g fresh weight.The synthesis of low molecular weight RNA and D-RNA is inhibited at concentrations more than 350μg FU

Treatment of etiolated and excisedCucurbita cotyledons with exogenous cytokinin (benzyladenine) in darkness or light results in a marked stimulation of Rubisco activity, content of enzyme protein, and incorporation of labelled precursors into it, ind

Summary RNA preparations from tobacco chloroplasts which were isolated by different methods besides 1.1 and 0.56 × 10 6 chloroplast rRNA’s contain always significant amounts of 1.3 and 0.7 × 10 6 cytoplasmic rRNA’s. Since the latter are of near
