In particular, the symbionts' thylakoid membranes
appear to play an important role, with their stability compromised and their membranes dissolving at higher temperatures (Hill et al., 2009; Diaz-Almeyda et al, 2011; Downs et al., 2013).
As Mn plays very important role in photosynthetic activity, hence the objective of the study was to measure the effect of Mn application methods on Photosystem-II activity of the isolated thylakoid membranes
under saline conditions.
Plastoglobules are lipoprotein subcompartments of the chloroplast that are permanently coupled to thylakoid membranes
and contain biosynthetic enzymes.
Photosystem II (PSII) of the photosynthetic apparatus is a multi subunit pigment-protein complex in the thylakoid membrane
, which performs light-induced oxidation of water and reduction of plastoquinone.

and PS II complexes isolated from Chlamydomonas reinhardtii," Aquatic Toxicology, vol.
Carotenoids are integral constituents of the thylakoid membrane
and are usually well associated with many of the proteins that constitute the photosynthetic apparatus (SIKUKU et al., 2010).
Among the molecules that protect the thylakoid membranes
against singlet oxygen are carotenoids and tocopherols and it is proposed that a [beta]-carotene molecule located at the PSII reaction center serves to quench singlet oxygen that may there be produced.
Topics include the role of cyanobacteria in earth history, cyanobacterial evolution from comparative genetics, gene transfer to cyanobacteria in the lab and in nature, molecular ecology and environmental genomics of cyanobacteria, comparative genomics of marine cyanobacteria and phages, stress responses in Synechocystis, bioactive compounds produced by cyanobacteria, the cyanobacterial circadian clock and the KaiC phosphorylation cycle, molecular structure of the photosynthetic apparatus, membrane systems, thylakoid membranes
, carbon acquisition, nitrogen assimilation, responses to absences of fixed nitrogen, cyanobiological nitrogen fixing in the ocean and cyanobacterial-plant symbiosis.
It also has been shown that the phospholipid composition of chloroplast thylakoid membranes
changes during cold exposure, but the changes were not related to cold tolerance (Vigh et al., 1985).
In mesophyll cells of CF-treated leaves, ovoid chloroplasts were tightly appressed to cells walls and had thylakoid membranes
with parallel alignment.
It leads to better-developed thylakoid membranes
, and larger choloroplasts.
In an upcoming BIOELECTROCHEMISTRY AND BIOENERGETICS, Greenbaum will report a technique for making electrical contact with the electron transport chain by depositing platinum particles onto thylakoid membranes
that had been isolated from spinach cells and trapped on fiberglass filter paper.
