Biosynthesis of α-Tocopherol and Plastoquinone-9 in spinach chloroplasts [PDF]

open access: yes, 1980
Prenylation and methylation reaction in al biosynthesis is localized in the envelope membranes of the chloroplasts, while PQ-9 biosynthesis takes place in the envelope membranes and also in the thylakoid membranes.

Melatonin Improves the Photosynthetic Apparatus in Pea Leaves Stressed by Paraquat via Chlorophyll Breakdown Regulation and Its Accelerated de novo Synthesis

open access: yesFrontiers in Plant Science, 2017
The positive effect of melatonin on the function of the photosynthetic apparatus is known, but little is known about the specific mechanisms of melatonin's action in plants. The influence of melatonin on chlorophyll metabolism of 24-day-old Pisum sativum

Assembly of the precursor and processed light-harvesting chlorophyll a/b protein of Lemna into the light-harvesting complex II of barley etiochloroplasts. [PDF]

open access: yes, 1986
When the in vitro synthesized precursor of a light-harvesting chlorophyll a/b binding protein (LHCP) from Lemna gibba is imported into barley etiochloroplasts, it is processed to a single form.

Overexpression of beta-carotene hydroxylase enhances stress tolerance in Arabidopsis [PDF]

open access: yes, 2002
Plant stress caused by extreme environmental conditions is already a principal reason for yield reduction in crops. The threat of global environment change makes it increasingly important to generate crop plants that will withstand such conditions ...

Influence of lead on the chlorophyll content and on initial steps of its synthesis in greening cucumber seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
Lead uptake by young cucumber (Couches satires L.) seedlings growing in 10-4 and 10-3 M PbCl2 solution caused δ-aminolevulinic acid synthesis inhibition, reduced the activity of δ-aminolevulinic acid dehydratase and the chlorophyll centent in the ...

A separation of the reactions in photosynthesis by means of intermittent light [PDF]

open access: yes, 1932
Experiments on photosynthesis in intermittent light have been made on two occasions. Brown and Escombe, in 1905, made use of a rotating sector to study the effect of light intensity on the photosynthesis of leaves.

Functional and mutational analysis of the light-harvesting chlorophyll a/b protein of thylakoid membranes. [PDF]

open access: yes, 1986
The precursor for a Lemna light-harvesting chlorophyll a/b protein (pLHCP) has been synthesized in vitro from a single member of the nuclear LHCP multigene family. We report the sequence of this gene.

Plastid redox state and sugars: Interactive regulators of nuclear-encoded photosynthetic gene expression [PDF]

open access: yes, 2001
Feedback regulation of photosynthesis by carbon metabolites has long been recognized, but the underlying cellular mechanisms that control this process remain unclear.

Hamowanie syntezy chlorofilu i RNA w izolowanych liścieniach ogórka przez N-hydroksymocznik [Inhibition of chlorophyll and RNA synthesis by N-hydroxyurea in detached cucumber cotyledons]

open access: yesActa Societatis Botanicorum Poloniae, 2015
N-hydroxyurea (HU) at the concentration of 5 x 10-4 M decreased the content of chlorophyll in detached cucumber cotyledons; at this concentration it has no inhibitory effect on growth.
