Neglecting acclimation of photosynthesis under drought can cause significant errors in predicting leaf photosynthesis in wheat

Global Change Biology, Volume 29, Issue 2, Page 505-521, January 2023., 2023
Our study investigated how photosynthesis and its components acclimate to drought stress (DS) and growth temperature (Tgrowth) in wheat, and examined to what extent ignoring these acclimations would lead to errors in predicting photosynthesis. We found that both diffusional and biochemical parameters of photosynthesis and their thermal sensitivity ...

Thermoluminescence in Chloroplast Thylakoid [PDF]

, 2012
Luminescence occurs in almost all the materials absorbing photon energy and is a phenomenon of light emitting process. There are various types of luminescence, e.g. fluorescence, phosphorescence, delayed luminescence, chemiluminescence and thermoluminescence.

Construction of exact minimal parking garages: nonlinear helical motifs in optimally packed lamellar structures [PDF]

Proc. R. Soc. A 477 (2021) 20200891, 2020
Minimal surfaces arise as energy minimizers for fluid membranes and are thus found in a variety of biological systems. The tight lamellar structures of the endoplasmic reticulum and plant thylakoids are composed of such minimal surfaces in which right and left handed helical motifs are embedded in stoichiometry suggesting global pitch balance.

One-step isolation and biochemical characterization of a highlyactive plant PSII monomeric core [PDF]

, 2011
We describe a one-step detergent solubilization protocol for isolating a highly active form of Photosystem II (PSII) from Pisum sativum L. Detailed characterization of the preparation showed that the complex was a monomer having no light harvesting ...

New insights into the Tat protein transport cycle from characterizing the assembled Tat translocon

Molecular Microbiology, Volume 118, Issue 6, Page 637-651, December 2022., 2022
The Tat translocon transports folded proteins via a unique and enigmatic mechanism. The translocon assembles transiently, only in the presence of a substrate, a protonmotive force, and only at native expression levels, and for this reason is exceedingly difficult to access experimentally.

Light Adaptation in Phycobilisome antennas: Influence on the Rod Length and Structural Arrangement [PDF]

J. Phys. Chem. B 121, 9196 (2017), 2017
Phycobilisomes, the light-harvesting antennas of cyanobacteria, can adapt to a wide range of environments thanks to a composition and function response to stress conditions. We study how structural changes influence excitation transfer in these super-complexes.

Isolation of wheat thylakoids for protein analysis

MethodsX, 2023
Thylakoids host a large number of proteins to confer photosynthesis and chemical biosynthesis essential for plant survival and growth. Successful isolation of high-quality thylakoids is the first step to studying the compositions and function of ...

Charge regulation radically modifies electrostatics in membrane stacks [PDF]

Phys. Rev. E 100, 050601 (2019), 2019
Motivated by biological membrane-containing organelles in plants and photosynthetic bacteria, we study charge regulation in a model membrane stack. Considering (de)protonation as the simplest mechanism of charge equilibration between the membranes and with the bathing environment, we uncover a symmetry-broken charge state in the stack with a ...

Biogenesis and origin of thylakoid membranes

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2001
Thylakoids are photosynthetically active membranes found in Cyanobacteria and chloroplasts. It is likely that they originated in photosynthetic bacteria, probably in close connection to the occurrence of photosystem II and oxygenic photosynthesis. In higher plants, chloroplasts develop from undifferentiated proplastids.
