Consequences of Decreased Light Harvesting Capability on Photosystem II Function in Synechocystis sp. PCC 6803

Life, 2014
Cyanobacteria use large pigment-protein complexes called phycobilisomes to harvest light energy primarily for photosystem II (PSII). We used a series of mutants with partial to complete reduction of phycobilisomes to examine the effects of antenna ...

Assessing plant water status: Part 1 – Classical methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

Sustained diurnal stimulation of cyclic electron flow in two tropical tree species Erythrophleum guineense and Khaya ivorensis

Frontiers in Plant Science, 2016
The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown.

Biochemical and biotechnological approaches as basis for structure determination of pigment-protein complexes of oxygenic photosynthesis [PDF]

, 2009
Today the structure of photosystem II, which is the enzyme responsible for the evolution of molecular oxygen by plants, algae and cyanobacteria, is known up to a resolution of about 3.0 Å in cyanobacteria (Loll et al., 2005).

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...

Trehalose as a tool for studying the molecular mechanisms of electron transfer in photosynthetic systems

Frontiers in Photobiology
In this review, we consider the effects of trehalose on charge transfer processes in three distinct photosynthetic systems under different conditions, namely: (i) the effect of relative hydration of the trehalose glassy matrix on forward and backward ...

Interaction of photosystem I from Phaeodactylum tricornutum with plastocyanins as compared with its native cytochrome c6: Reunion with a lost donor [PDF]

, 2015
In the Phaeodactylum tricornutum alga, as in most diatoms, cytochrome c6 is the only electron donor to photosystem I, and thus they lack plastocyanin as an alternative electron carrier.

Polymeric nano‐delivery of gibberellic acid enhances fruit quality, yield and pedicel strength in grapevine (Vitis vinifera L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Nanoparticulate systems offer an effective strategy for the targeted delivery of agrochemicals and for enhancing their efficacy. This study aimed to synthesize and characterize gibberellic acid (GA3)‐loaded poly(d,l‐lactic‐co‐glycolic acid) nanoparticles (PLGA NPs) and to evaluate the effects of their application on the flower ...

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.
