Transmission Electron Microscopy for Tobacco Chloroplast Ultrastructure
Bio-Protocol, 2015 The chloroplast is the site of photosynthesis that enabled and sustains aerobic life on Earth. Chloroplasts are relatively large organelles with a diameter of ~5 μm and width of ~2.5 μm, and so can be readily analysed by electron microscopy.

Reciprocal regulation of protein synthesis and carbon metabolism for thylakoid membrane biogenesis [PDF]
, 2013 Metabolic control of gene expression coordinates the levels of specific gene products to meet cellular demand for their activities. This control can be exerted by metabolites acting as regulatory signals and/or a class of metabolic enzymes with dual ...

The FEBS Journal, EarlyView.Twin‐arginine translocation D (TatD) homologs are found across all kingdoms, with debated roles in DNA degradation and protein quality control in unicellular organisms. We characterize TATDN1, the mammalian TatD orthologue, as a proteostatic stress‐responsive cytosolic protein dispensable for DNA degradation.

The permeability of the thylakoid membrane for protons
FEBS Letters, 1984 Parallel measurements of light‐induced proton gradients and of electron transport rates were used to characterize proton efflux in lettuce chloroplasts. Proton efflux mediated by the chloroplast H+‐ATPase was resolved from nonspecific leakage, through its dependence on the ratio of internal to external proton concentrations; proton leakage was ...

Journal of Microscopy, EarlyView.Abstract Until recently, the lack of three‐dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER).

Kinetic models of photosystem II should accommodate the effect of donor side quenching on variable chlorophyll a fluorescence in the microseconds time [PDF]
, 2009 Quantitative data on laser flash-induced variable fluorescence in the 100 ns to 1 ms time range (Belyaeva et al. in Photosynth Res 98:105–119, 2008) confirming those of others (Steffen et al.

BMC Plant Biology, 2017 Background The preparation of functional thylakoid membranes from diatoms with a silica cell wall is still a largely unsolved challenge. Therefore, an optimized protocol for the isolation of oxygen evolving thylakoid membranes of the centric diatom ...

New Phytologist, EarlyView.Summary Light‐induced structural changes in thylakoid membranes have been reported for decades, with conflicting data regarding their shrinkage or expansion during dark–light transitions. Understanding these dynamics is important for both fundamental photosynthesis research and agricultural applications. This research investigated the temporal sequence

Uncoupling of Spinach Thylakoids by Gramine
Zeitschrift für Naturforschung C, 1984 Abstract The indol alkaloid gramine inhibited photophosphorylation, Pi-ATP exchange reaction and proton gradient, and enhanced electron transport in spinach thylakoids with I 50 around 0.2 mᴍ. It thus behaves as a typical uncoupler of photophosphorylation.

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]
, 1987 The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with
