Characterization of protoheme levels in etiolated and greening plant tissues.
The protoheme content of etiolated, greening, and fully greened bean (Phaseolus vulgaris L. var. Light Red Kidney) leaves has been studied. The protoheme level in etiolated and fully greened leaf tissue stays relatively constant from age 7 to 14 days. In agreement with the studies reported for barley (Castelfranco and Jones 1975 Plant Physiol 55: 485-490), the protoheme content of greening bean...
متن کاملChanges in Lipid Composition during Greening of Etiolated Pea Seedlings.
After 7 days of germination in the dark, the three sections of pea seedlings studied (cotyledons, stems, and young leaves) are rich in linoleic acid; after illumination of the seedlings a very significant increase in linolenic acid is observed in the young leaves section, whereas only small variations are noted in the fatty acid composition of the other sections. The increase in linolenic acid ...
متن کاملDevelopment of the Primary Photochemical Apparatus of Photosynthesis during Greening of Etiolated Bean Leaves.
Seven-day-old dark-grown bean leaves were greened under continuous light. The amount of chlorophyll, the ratio of chlorophyll a to chlorophyll b, the O(2) evolving capacity and the primary photochemical activities of Photosystem I and Photosystem II were measured on the leaves after various times of greening. The primary photochemical activities were measured as the photo-oxidation of P(700), t...
متن کاملStable Membrane-Association of mRNAs in Etiolated, Greening and Mature Plastids
Chloroplast genes are transcribed as polycistronic precursor RNAs that give rise to a multitude of processing products down to monocistronic forms. Translation of these mRNAs is realized by bacterial type 70S ribosomes. A larger fraction of these ribosomes is attached to chloroplast membranes. This study analyzed transcriptome-wide distribution of plastid mRNAs between soluble and membrane frac...
متن کاملEffect of the hypocotyl hook on greening in etiolated cucumber cotyledons.
Four-day-old etiolated cucumber cotyledons (Cucumis sativus, L.) were excised and allowed to green in white fluorescent light at 28 C. Cotyledons excised with a full hypocotyl hook exhibited a lag phase of 1 hour before entering the rapid greening phase, whereas cotyledons excised without any hypocotyl hook exhibited a lag phase of 6 hours. Cotyledons excised with varying lengths of hypocotyl h...
