Quality control of photosystem II: lipid peroxidation accelerates photoinhibition under excessive illumination. [PDF]

PLoS ONE, 2012
Environmental stresses lower the efficiency of photosynthesis and sometimes cause irreversible damage to plant functions. When spinach thylakoids and Photosystem II membranes were illuminated with excessive visible light (100-1,000 µmol photons m(-1) s ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, EarlyView.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Correlation between spatial (3D) structure of pea and bean thylakoid membranes and arrangement of chlorophyll-protein complexes

BMC Plant Biology, 2012
Background The thylakoid system in plant chloroplasts is organized into two distinct domains: grana arranged in stacks of appressed membranes and non-appressed membranes consisting of stroma thylakoids and margins of granal stacks.

Multiscale Analysis and Optimisation of Photosynthetic Solar Energy Systems [PDF]

arXiv, 2014
This work asks how light harvesting in photosynthetic systems can be optimised for economically scalable, sustainable energy production. Hierarchy theory is introduced as a system-analysis and optimisation tool better able to handle multiscale, multiprocess complexities in photosynthetic energetics compared with standard linear-process analysis.

Thermal tolerance is linked to anatomical but not morphological leaf traits in woody species of Andean tropical montane forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.

The rotational model: a new hypothesis for thylakoid stacking

International Journal of Plant Biology, 2016
The most enigmatic feature of mature thylakoids of Angiosperms is the presence of piles of membranous discs forming the cylindrical structures known as grana.

Some adaptations of the anthocerophyte Megoceros pellucidus (Colenso) E.A.Hodgs. to extremely low light environments : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, Palmerston North, New Zealand [PDF]

, 2002
The New Zealand Anthocerophyte Megaceros pellucidus (Colenso) is found in wet, cool temperate rain forest and is associated with extremely low light habitats (0.5-7 μmoles photons m−² s−¹). The light available to M.

Conservation of core complex subunits shaped the structure and function of photosystem I in the secondary endosymbiont alga Nannochloropsis gaditana [PDF]

, 2017
Photosystem I (PSI) is a pigment protein complex catalyzing the light-driven electron transport from plastocyanin to ferredoxin in oxygenic photosynthetic organisms.

Diatom triacylglycerol metabolism: from carbon fixation to lipid droplet degradation

Biological Reviews, EarlyView.
ABSTRACT Diatoms are a prominent microalgae family that has attracted interest for its production of molecules of biotechnological interest. Their fatty acid profile is rich in health‐beneficial omega‐3 eicosapentaenoic acid (EPA). Furthermore, under nutrient‐deprived conditions, many diatom species, notably Phaeodactylum tricornutum, Thalassiosira ...

Photoelectrochemical cells based on photosynthetic systems: a review [PDF]

Biofuel Research Journal, 2015
Photosynthesis is a process which converts light energy into energy contained in the chemical bonds of organic compounds by photosynthetic pigments such as chlorophyll (Chl a, b, c, d, f) or bacteriochlorophyll. It occurs in phototrophic organisms, which
