“…Klein et al (21) and Holowinsky and O'Brien (unpublished), however, found no clear far red reversal of the red light induction of some structural changes during chloroplast development. The synthesis of several photosynthetic enzymes has been shown to be triggered or mediated by the phytochrome system (12,18,26,27).…”

“…The changes were much smaller if the dark-grown plants were irradiated either with red light followed by far red light, or with far red light alone. Thus continuous light is not essential for the production of ribosomal RNA in plastids, and the levels of ribosomal RNA found in chloroplasts can also be attained in etioplasts of pea leaves in the dark provided the leaf phytochrome is maintained in its active form.Evidence from several laboratories has shown that phytochrome mediates in photoregulating the synthesis of chloroplast proteins (3,5,(13)(14)(15)19). Thus activation of the phytochrome system in dark-grown pea seedlings by a brief irradiation with red light results in a marked increase in the synthesis of ribulose-1 ,5-diphosphate carboxylase and other chloroplast enzymes in the dark (3,19).…”

Dark-grown pea seedlings (Pisum sativum L.) were irradiated for a short period each day with low intensity red light (662 nm), red light immediately followed by far red light (730 nm), or far red light alone. Other plants were transferred to a white light regime (14 hours light/10 hours dark). There was no change in the amount of RNA in the tissue on a fresh weight basis after the various treatinents. However, compared with dark-grown seedlings, those plants irradiated with red light showed an increase in the net RNA content per stem apex. In addition there was a two-to threefold increase in ribosomal RNA of the etioplasts relative to the total ribosomal RNA. These increases were comparable to those found in plants grown in the white light regime. The changes were much smaller if the dark-grown plants were irradiated either with red light followed by far red light, or with far red light alone. Thus continuous light is not essential for the production of ribosomal RNA in plastids, and the levels of ribosomal RNA found in chloroplasts can also be attained in etioplasts of pea leaves in the dark provided the leaf phytochrome is maintained in its active form.Evidence from several laboratories has shown that phytochrome mediates in photoregulating the synthesis of chloroplast proteins (3,5,(13)(14)(15)19). Thus activation of the phytochrome system in dark-grown pea seedlings by a brief irradiation with red light results in a marked increase in the synthesis of ribulose-1 ,5-diphosphate carboxylase and other chloroplast enzymes in the dark (3,19). Continuous light then is not required for the synthesis of Calvin cycle enzymes, nor is it required for svnthesis of enzymes of the C4-dicarboxylic acid pathway of photosynthesis (4).At least some of these chloroplast proteins appear to be synthesized on chloroplast ribosomes (17,19,20), but it is not known whether the phytochrome-mediated increase in plastid protein synthesis involves an increase in the number of plastid ribosomes or whether these ribosomes are already present in the etioplasts of dark-grown plants. Continuous light is known to increase the amount of plastid rRNA (1,8,22) and also plastid RNA polymerase (2) In the experiments reported here, we have measured the amount of plastid and cytoplasmic rRNA in the apices of darkgrown pea seedlings and in seedlings subjected to various light regimes. The leaves of dark-grown seedlings contained lower amounts of chloroplast-type rRNA (16 S and 23 S) compared with green leaves, but after irradiating the seedlings with light at 662 nm for short periods, the 16 S and 23 S RNA increased to the levels found in the leaves of green plants of the same chronological age. MATERIALS AND METHODSPea seeds (Pisum sativum L., cv Greenfeast, obtained from Yates Seed Co., Sydney) which had not been treated with fungicide or preservatives were used. The seeds were washed in a dilute solution of detergent (1% Teepol, Shell Chemical Co.), soaked in 3% (v/v) Chlorize (Nightingale Chemical Co., Sydney) for 15 min and then washed...

“…A phytochrome-mediated regulation of NADP-GPD in etiolated tissue has been previously suggested (10,19,21,29). Contrary to this, Ireland and Bradbeer (15) favor the concept of a photosynthesis-dependent activation of NADP-GPD, as earlier proposed by Muller (27) for photosynthetic tissue.…”

“…The light-induced increase of NADP-GPD activity in etiolated seedlings, first demonstrated by Hageman and Arnon (11), has been shown to be independent of photosynthesis but dependent on phytochrome (10,19,21,29). Recently, however, a second activation mechanism mediated by photosynthesis has been proposed (27).…”

The development of NADP-and NAD-dependent glyceraldehyde 3-phosphate dehydrogenase and NADH-specific glyoxylate reductase was These results are consistent with the following conclusions. 1. The light-induced increase of the three enzyme activities is mediated by phytochrome and is independent of photosynthesis.2. The activities of the NADP-and NAD-glyceraldehyde 3-phosphate dehydrogenase are regulated differentially, indicating the existence of a NADP-specific enzyme in S. alba cotyledons.3. This differential regulation is in contrast to the apparent correlated regulation of the activities of NADP-glyceraldehyde 3-phosphate dehydrogenase and glyoxylate reductase. 4. The increase in activity of NADP-glyceraldehyde 3-phosphate dehydrogenase and glyoxylate reductase is dependent on both chloroplast and cytoplasmic protein synthesis, whereas the 1 This work was supported by a grant of the Studienstiftung des Deutschen Volkes and by the Deutsche Forschungsgemeinschaft (SFB 46). increase in activity of NAD-glyceraldehyde 3-phosphate dehydrogenase is only dependent on the latter.
