PagHCF106 negatively regulates drought stress tolerance in poplar (Populus alba × Populus glandulosa) by modulating stomatal aperture.

Modulation of stomatal development and movement is a promising approach for creating water-conserving plants. Here, we identified and characterized the PagHCF106 gene of poplar (Populus alba × Populus glandulosa). The PagHCF106 protein localized predominantly to the chloroplast, and the PagHCF106 gene exhibited tissue-specific expression pattern.

ELONGATED HYPOCOTYL 5 promotes root growth by maintaining redox homeostasis and repressing oxidative stress response.

Oxidative stress is a major threat to plant growth and survival. To understand how plants cope with oxidative stress, we carried out a genetic screen for Arabidopsis (Arabidopsis thaliana) mutants with altered response to hydrogen peroxide (H2O2) in root growth. Herein, we report the characterization of one of the hypersensitive mutants obtained.

DNDMH enabled C(sp)-H nitration of aryl alkenes.

C(sp)-H bond nitration provides facile access to nitro compounds that are inaccessible through traditional nitration pathways. This work describes a C(sp)-H bond nitration of aryl alkenes using DNDMH, a nitration reagent developed previously in our lab. Notably, this novel nitration process presents excellent regioselectivity and chemoselectivity between C(sp)-H nitration and C(sp)-H nitration.

Extending Badger's rule. I. The relationship between energy and structure in hydrogen bonds.

We derive a new expression for the strength of a hydrogen bond (VHB) in terms of the elongation of the covalent bond of the donor fragment participating in the hydrogen bond (ΔrHB) and the intermolecular coordinates R (separation between the heavy atoms) and θ (deviation of the hydrogen bond from linearity). The expression includes components describing the covalent D-H bond of the hydrogen bond donor via a Morse potential, the Pauli repulsion, and electrostatic interactions between the constituent fragments using a linear expansion of their dipole moment and a quadratic expansion of their polarizability tensor. We fitted the parameters of the model using ab initio electronic structure results for six hydrogen bonded dimers, namely, NH3-NH3, H2O-H2O, HF-HF, H2O-NH3, HF-H2O, and HF-NH3, and validated its performance for extended parts of their potential energy surfaces, resulting in a mean absolute error ranging from 0.

Predicting phage-host interaction via hyperbolic Poincaré graph embedding and large-scale protein language technique.

Bacteriophages (phages) are increasingly viewed as a promising alternative for the treatment of antibiotic-resistant bacterial infections. However, the diversity of host ranges complicates the identification of target phages. Existing computational tools often fail to accurately identify phages across different bacterial species.

Evidence of a 4.33 billion year age for the Moon's South Pole-Aitken basin.

The Moon's farside South Pole-Aitken (SPA) basin is the largest and oldest visible impact basin in the inner Solar System. Determining the timing of this catastrophic event is key to understanding the onset of the lunar basin-forming epoch, with implications for understanding the impact bombardment history of the inner Solar System. Despite this, the formation age of the SPA basin remains poorly constrained.

U in a Conserved Pseudotetrahedral Imidophosphorane Coordination Sphere.

While several ligand systems support uranium across a range of oxidation states, spanning more than two oxidation states in a conserved coordination geometry is uncommon among structurally authenticated complexes. Imidophosphorane ligands significantly stabilize high-valent lanthanide and actinide complexes. Here, we report a series of homoleptic uranium imidophosphorane complexes, spanning the +4, +5 and +6 oxidation states in a four-coordinate pseudotetrahedral ligand field.

Clin-STAR Corner: Rehabilitation for Older Adults With Heart Failure.

Heart failure is a major contributor to morbidity, mortality, and healthcare costs, especially among older adults. Despite a large body of evidence supporting the benefits of cardiac rehabilitation, less than 30% of eligible Medicare beneficiaries participate in cardiac rehabilitation. Thus, it is essential to examine alternatives, such as physical rehabilitation, a rehabilitation approach that focuses on physical activity and function.

Determination of Pathogens in Surgical Site Infections in Ankle Fractures and Implications for Empirical Antibiotic Treatment.

Surgical site infections (SSIs) are the most common complication after surgery for ankle fractures. This retrospective study aimed to determine the pathogens cultured in SSI and their antimicrobial susceptibility patterns to provide a recommendation for empirical therapy. Patients who underwent surgical treatment for an ankle fracture were included.

CaML: Chemistry-informed machine learning explains mutual changes between protein conformations and calcium ions in calcium-binding proteins using structural and topological features.

Proteins' flexibility is a feature in communicating changes in cell signaling instigated by binding with secondary messengers, such as calcium ions, associated with the coordination of muscle contraction, neurotransmitter release, and gene expression. When binding with the disordered parts of a protein, calcium ions must balance their charge states with the shape of calcium-binding proteins and their versatile pool of partners depending on the circumstances they transmit. Accurately determining the ionic charges of those ions is essential for understanding their role in such processes.

Organic manure and fertilizer N management strategies improve soil health at different growth stages of pearl millet under pearl millet-wheat sequence.

Background: Incorporating organic manure improves soil properties and crop productivity. A long-term study started in October 1967 examined the effects of farmyard manure and nitrogen fertilization on the soil at key growth stages of pearl millet in a pearl millet-wheat cropping system over its 51st cycle.

Results: Applying 15 Mg of farmyard manure (FYM) per hectare in both growing seasons significantly boosted soil organic carbon (SOC), dissolved organic carbon (DOC), and key nutrients compared to one-season application.

Petrophysical assessment of the Hammam Faraun, Matulla and Nubia Reservoirs in the Ashrafi Oil Field, Gulf of Suez.

The Hammam Faraun, Matulla, and Nubia formations in the Ashrafi oil field, in the southern Gulf of Suez, Egypt, are key hydrocarbon reservoirs with significant economic importance. These formations, characterized by their favorable reservoir properties and structural settings, play a crucial role in oil and gas accumulation. Their study provides valuable insights into regional petroleum systems and guides exploration and production activities.

Impacts of irrigation expansion on moist-heat stress based on IRRMIP results.

Irrigation rapidly expanded during the 20 century, affecting climate via water, energy, and biogeochemical changes. Previous assessments of these effects predominantly relied on a single Earth System Model, and therefore suffered from structural model uncertainties. Here we quantify the impacts of historical irrigation expansion on climate by analysing simulation results from six Earth system models participating in the Irrigation Model Intercomparison Project (IRRMIP).

Posttranslational modifications in cardiac metabolic remodeling mediated by metabolites: Implications for disease pathology and therapeutic potential.
