A Commonly Used Photosynthetic Inhibitor Fails to Block Electron Flow to Photosystem I in Intact Systems

open access: yesFrontiers in Plant Science, 2020
In plant science, 2,4-dinitrophenylether of iodonitrothymol (DNP-INT) is frequently used as an alternative to 2,5-dibromo-6-isopropyl-3-methyl-1,4-benzoquinone (DBMIB) to examine the capacity of plastoquinol and semiquinone to reduce O2.

Interaction of flavodoxin with cyanobacterial thylakoids

open access: yesPhotosynthesis Research, 1993
Flavodoxin from the cyanobacterium Anabaena PCC 7119 has been shown to mediate, under illumination, the transfer of electrons from the thylakoidal membranes that were isolated from the same organism, to both the enzyme ferredoxin-NADP(+) reductase and cytochrome c.

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

open access: yesBMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

A structure of the relict phycobilisome from a thylakoid-free cyanobacterium

open access: yesNature Communications, 2023
Phycobilisomes (PBS) are antenna megacomplexes that transfer energy to photosystems II and I in thylakoids. PBS likely evolved from a basic, inefficient form into the predominant hemidiscoidal shape with radiating peripheral rods.

Biogenesis and origin of thylakoid membranes

open access: yesBiochimica 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.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Symbiotic Germination Technique of an Endangered Epiphytic Orchid Dendrobium sinominutiflorum: A Promising Conservation Application 濒危附生兰科植物勐海石斛 (Dendrobium sinominutiflorum) 的共生萌发技术:一种具有应用前景的保护策略

open access: yesIntegrative Conservation, EarlyView.
We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Thylakoid membrane function in heterocysts

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2016
Multicellular cyanobacteria form different cell types in response to environmental stimuli. Under nitrogen limiting conditions a fraction of the vegetative cells in the filament differentiate into heterocysts. Heterocysts are specialized in atmospheric nitrogen fixation and differentiation involves drastic morphological changes on the cellular level ...
