In this study, an exterior T-DNA was randomly inserted into the genome of M.

The Thermodynamic and Kinetic Properties of the dA-rU DNA-RNA Hybrid Base Pair Investigated via Molecular Dynamics Simulations.

DNA-RNA hybrid duplexes play essential roles during the reverse transcription of RNA viruses and DNA replication. The opening and conformation changes of individual base pairs are critical to their biological functions. However, the microscopic mechanisms governing base pair closing and opening at the atomic level remain poorly understood.

Palladium-catalyzed C-H bond activation and decarboxylation for the assembly of indolo[1,2-]phenanthridine.

A direct and convenient strategy for the assembly of indolo[1,2-]phenanthridine a Pd-catalyzed tandem cyclization reaction is presented. The current strategy delivers a range of indolo[1,2-]phenanthridine derivatives by utilizing readily available 1-(2-iodophenyl)-1-indole and commercially available -bromobenzoic acids as the starting materials. The reaction features the formation of two C-C bonds through Pd-catalyzed C-H bond activation and decarboxylation.

Integrated transcriptomics, metabolomics and physiological analyses reveal differential response mechanisms of wheat to cadmium and/or salinity stress.

Many soils face dual challenges of cadmium (Cd) contamination and salinization. However, the response of crops, especially wheat, to combined Cd and salinity stress is not understood. Here, wheat was grown in a hydroponic model for 14 days under single and combined Cd and NaCl stresses.

An Unexpected Access to Phospholene Fused β-Phosphinolactams by the Reaction of α-C-Bridged Biphospholes and Nitrones.

An efficient and practical method for the preparation of the phospholene fused β-phosphinolactam skeleton from α-C-bridged biphospholes and nitrones is described. The dissociation of biphospholes generates transient 1-phosphafulvenes, followed by oxidation with nitrones to give the 1-phosphafulvene oxides. The oxidation of 1-phosphafulvene boosts its reactivity toward imine, leading to the isolated products.

Catalyst-free regioselective sulfonylation of phenoxazine with sulfonyl hydrazides in HO/HFIP.

A facile catalyst-free sulfonylation of phenoxazine with sulfonyl hydrazides was efficiently developed in HO/HFIP without any catalyst. This metal- and catalyst-free protocol is suitable for aromatic and aliphatic reagents to afford the corresponding sulfones in moderate to high yields. A gram-scale experiment was performed to assess the practicability of the method.

Biocontrol mechanisms of poplar leaf blight due to Nigrospora oryzae.

Nigrospora oryzae, a newly identified pathogen, is responsible for poplar leaf blight, causing significant harm to poplar growth. Here, we describe, for the first time, a biological control method for the control of poplar leaf blight via the applications of 3 dominant Trichoderma strains/species. In this study, dominant Trichoderma species/strains with the potential for biocontrol were identified and then further characterised via dual culture assays, volatile organic compounds (VOCs), and culture filtrates.

A strategy involving the use of 3D self-supporting B·N co-doped carbon nanofiber composite solid polymer electrolytes to stabilize the interface between polymer electrolytes and lithium metal.

Prediction of individual performance and verbal intelligence scores from resting-state fMRI in children and adolescents.

The neuroimaging basis of intelligence remains elusive; however, there is a growing body of research employing connectome-based predictive modeling to estimate individual intelligence scores, aiming to identify the optimal set of neuroimaging features for accurately predicting an individual's cognitive abilities. Compared to adults, the disparities in cognitive performance among children and adolescents are more likely to captivate individuals' interest and attention. Limited research has been dedicated to exploring neuroimaging markers of intelligence specifically in the pediatric population.
