This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Structures and proton-pumping strategies of mitochondrial respiratory enzymes [PDF]
Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the energy made available from electron transfer reactions to transport protons across the inner mitochondrial membrane and create an electrochemical gradient used for the ...

The multidimensional regulation roles and mechanisms of calcium in fruit quality
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

A FAMILY OF CATION ATPASE-LIKE MOLECULES FROM PLASMODIUM-FALCIPARUM [PDF]
. We report the nucleotide and derived amino acid sequence of the ATPase 1 gene from Plasmodium falciparum. The amino acid sequence shares homology with the family of "P-type cation transloeating ATPases in conserved regions important for nucleotide

The Role of Oxidative Stress in Periodontitis
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

On the chimerical nature of the membrane-bound ATPase from halobacterium saccharovorum [PDF]
A series of experiments are described that were carried out with the goal of determining how the membrane-bound ATPase from H. saccharovorum is related to V- and F-type ATPases.

ubiquinone oxidoreductase (complex I) in Escherichia coli [PDF]
The proton-pumping NADH:ubiquinone oxidoreductase, respiratory complex I, couples the electron transfer from NADH to ubiquinone with the translocation of protons across the membrane.

Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

A new type of Na+-driven ATP synthase membrane rotor with a two-carboxylate ion-coupling motif [PDF]
: The anaerobic bacterium Fusobacterium nucleatum uses glutamate decarboxylation to generate a transmembrane gradient of Na+. Here, we demonstrate that this ion-motive force is directly coupled to ATP synthesis, via an F1Fo-ATP synthase with a novel Na ...

Optimization of photobiomodulation therapy for spinal cord injury: A review
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...
