Development of Chloroplasts

1995
The central question in developmental physiology is the connection between genetic information and morphology (specific form): $$ DNA\; - - - - \mathop { - - - - \to }\limits^{mechanism} \;{\rm{specific form}}{\rm{.}} $$

Structural organization of developing chloroplasts inEuglena

Protoplasma, 1974
Dark-grownEuglena cells were exposed to light for 0, 6, 12, 24 and 48 hours. At each of these periods samples were taken for chlorophyll determination, measurements of O2 evolution and thin sectioning. For freeze-etching studies, plastids at the various developmental stages were separated on Urografin gradients.

Chloroplast ribosome release factor 1 (AtcpRF1) is essential for chloroplast development

Plant Molecular Biology, 2007
To study the functions of nuclear genes involved in chloroplast development, we systematically analyzed albino and pale green Arabidopsis thaliana mutants by use of the Activator/Dissociation (Ac/Ds) transposon tagging system. In this study, we focused on one of these albino mutants, designated apg3-1 (for a lbino or p ale g reen mutant 3).

Photoreactions in Chloroplast Development

1987
Chloroplast development in higher plants has a well known requirement for light. Chlorophyll, one of the most conspicuous components of chloroplasts is formed via a pathway (Fig. 1) which has its own specific light requirement. This is to satisfy the reactions involved in the synthesis of 5-aminolaevulinic acid (ALA) and the reduction of ...

Chloroplast Development in Rye Coleoptiles

Botanica Acta, 1994
AbstractIn the parenchyma cells of 1‐d‐old dark‐grown rye coleoptiles (Secale cereale) proplastids occurred which sometimes contained starch grains. During coleoptile growth in darkness starch‐filled amyloplasts are formed from the preexisting proplastids.

Phytochrome and chloroplast development

Endeavour, 1977
Abstract The regular development of plants depends upon their correct interpretation of photosignals from the environment. The most important sensor pigment involved in this process is the chromoprotein phytochrome. This article reviews the role of phytochrome with particular reference to experiments carried out with seedlings of the mustard plant ...

Phytochrome Control of Chloroplast Development

Biochemie und Physiologie der Pflanzen, 1986
Summary Of a number of light dependent responses that are modulated by phytochrome, one that has. incited interest in recent years is its control of other pigments, the chlorophylls and carotenoids. The light mediated transformation of etioplasts to chloroplasts involves, besides pigment acrumulation, ehanges in thr composition and structure of these

Chloroplast development: Energy transfer and structure

Archives of Biochemistry and Biophysics, 1961
Abstract Excitation energy absorbed by carotenoid pigments is not transferred to newly formed chlorophyll a in etiolated leaves. The capacity for energy transfer develops during a dark period following the photoconversion of protochlorophyll. This presumably is the time required for the formation of lamellae which incorporate both the carotenoid and ...

Evolutionary Development of Redox Regulation in Chloroplasts

Antioxidants & Redox Signaling, 2014
The post-translational modification of thiol groups stands out as a key strategy that cells employ for metabolic regulation and adaptation to changing environmental conditions. Nowhere is this more evident than in chloroplasts-the O2-evolving photosynthetic organelles of plant cells that are fitted with multiple redox systems, including the thioredoxin
