Subcellular Mechanisms of Se(IV) Reduction in Stenotrophomonas bentonitica: Linking Environmental Detoxification and Antimicrobial Activity of Se Nanostructures Within a Circular Economy Framework

open access: yesMicrobial Biotechnology, Volume 18, Issue 12, December 2025.
Stenotrophomonas bentonitica reduces Se(IV) via compartment‐specific pathways in the cytoplasm and membrane, yielding amorphous SeNPs coated with a protein‐rich organic corona. Biogenic SeNPs trigger strain‐specific toxicity: ROS‐mediated oxidative and genotoxic stress in Escherichia coli, and early membrane disruption in Staphylococcus aureus ...

Expression of the minor isoform pea ferredoxin in tobacco alters photosynthetic electron partitioning and enhances cyclic electron flow [PDF]

open access: yes, 2012
Ferredoxins (Fds) are ferrosulfoproteins that function as low-potential electron carriers in plants. The Fd family is composed of several isoforms that share high sequence homology but differ in functional characteristics.

Bacterial fitness for plant colonization is influenced by plant growth substrate

open access: yesNew Phytologist, Volume 248, Issue 6, Page 3168-3190, December 2025.
Summary Despite advances in our understanding of bacterial plant colonization, the extent to which growth substrate influences the molecular mechanisms enabling bacteria to efficiently colonize plants remains poorly understood. To address this, we used randomly barcoded transposon mutagenesis sequencing (RB‐TnSeq) in Paraburkholderia graminis OAS925 ...

Photosynthesis [PDF]

open access: yes, 2016
Photosynthesis sustains virtually all life on planet Earth providing the oxygen we breathe and the food we eat; it forms the basis of global food chains and meets the majority of humankind's current energy needs through fossilized photosynthetic fuels ...

Proteomic insights on root and tuber crops’ response to abiotic stress—A review

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract Root and tuber crops are a good source of food energy on a global scale, particularly in African and Asian nations. Nevertheless, these crops can be susceptible to abiotic stresses such as excessive heat, high salinity, drought, and nutrient deficiencies, which have detrimental effects on the physiological and metabolic processes of the plants,

A General Tool for Engineering the NAD/NADP Cofactor Preference of Oxidoreductases [PDF]

open access: yes, 2017
The ability to control enzymatic nicotinamide cofactor utilization is critical for engineering efficient metabolic pathways. However, the complex interactions that determine cofactor-binding preference render this engineering particularly challenging ...

Iron physiology and metabolism of model phytoplankton taxa in a western boundary continental shelf ecosystem

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3335-3354, November 2025.
Abstract Continental shelf ecosystems support diverse phytoplankton communities that contribute to global primary productivity. Iron is an important micronutrient controlling the growth of marine phytoplankton, but its role in influencing phytoplankton ecophysiology in western boundary continental shelf ecosystems is understudied.

Photosynthetic electron transport activity in heat-treated barley leaves: The role of internal alternative electron donors to photosystem II [PDF]

open access: yes, 2007
Electron transport processes were investigated in barley leaves in which the oxygen-evolution was fully inhibited by a heat pulse (48 °C, 40 s).

Hidden protein disorder: Deciphering the structural organisation and dynamics of a non‐canonical CP12 from the diatom Thalassiosira pseudonana

open access: yesThe FEBS Journal, Volume 292, Issue 21, Page 5855-5870, November 2025.
The Alphafold model of the atypical CP12 protein from the diatom Thalassiosira pseudonana did not correspond to small‐angle X‐ray scattering (SAXS) data. By combining site‐directed spin labelling electron paramagnetic resonance experiments (SDSL‐EPR) and molecular dynamics (MD) simulations, we deciphered the structural dynamics of this CP12, revealing ...
