The NAD kinase OsNADK1 affects the intracellular redox balance and enhances the tolerance of rice to drought

BMC Plant Biology, 2020
Background NAD kinases (NADKs) are the only known enzymes that directly phosphorylate NAD(H) to generate NADP(H) in different subcellular compartments. They participate in multiple life activities, such as modulating the NADP/NAD ratio, maintaining the ...

Indirect Export of Reducing Equivalents From the Chloroplast to Resupply NADP for C3 Photosynthesis—Growing Importance for Stromal NAD(H)?

Frontiers in Plant Science, 2021
Plant productivity greatly relies on a flawless concerted function of the two photosystems (PS) in the chloroplast thylakoid membrane. While damage to PSII can be rapidly resolved, PSI repair is complex and time-consuming. A major threat to PSI integrity

USP5 Stabilizes TGFBR1 to Drive Vascular Smooth Muscle Cell Senescence and Atherosclerosis

Advanced Science, EarlyView.
This study reveals that USP5 drives vascular smooth muscle cell senescence and atherosclerosis by stabilizing TGFBR1, suppressing IDH2, and promoting glycolytic reprogramming, identifying the USP5‐TGFBR1‐IDH2 axis as a potential therapeutic target. ABSTRACT Vascular smooth muscle cell (VSMC) senescence contributes importantly to atherosclerotic plaque ...

Production of flavour compounds by wine yeasts is dependent on the management of their intracellular redox balance

IVES Technical Reviews, 2023
Wine yeasts produce ethanol and a myriad of other metabolites during fermentation that give the final wine its unique organoleptic fingerprint. The complex network of metabolic pathways leading to the production of these flavour compounds is largely ...

The effects of abiotic stresses on the NADP-dependent malic enzyme in the leaves of the hexaploid wheat

, 2011
The objective of this study was to examine the effects of different abiotic stresses on the activity of an NADP-dependent malic enzyme (NADP-ME) and the corresponding gene transcription in the leaves of the hexaploid wheat (Triticum aestivum L.) The ...

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

Advanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

Structural backgrounds for the formation of a catalytically competent complex with NADP(H) during hydride transfer in ferredoxin–NADP+ reductases [PDF]

, 2012
The role of the highly conserved C266 and L268 of pea ferredoxin–NADP+ reductase (FNR) in formation of the catalytically competent complex of the enzyme with NADP(H) was investigated.

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice

Advanced Science, EarlyView.
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

A Partial C4 Photosynthetic Biochemical Pathway in Rice

Frontiers in Plant Science, 2020
Introduction of a C4 photosynthetic pathway into C3 rice (Oryza sativa) requires installation of a biochemical pump that concentrates CO2 at the site of carboxylation in modified bundle sheath cells. To investigate the feasibility of this, we generated a
