State of the Art of Low-Frequency Acoustic Modulation: Intensity Enhancement and Directional Control.

High-intensity low-frequency acoustic sources with directivity play a significant role in various fields such as medical treatment, underwater communication, and environmental monitoring. However, the long wavelengths, strong penetration, and their tendency to easily diffract of low-frequency acoustic waves make it challenging to achieve directional control and intensity enhancement. Thanks to the development of acoustic metamaterials, acoustic devices can now effectively manipulate low-frequency acoustic waves at subwavelength scales with excellent acoustic performance.

Comparison of Soil Microbial Composition in Rhizospheres Between Wilt Disease-Resistant and Susceptible Melon Varieties.

To screen out the bio-control soil microorganisms for preventing melon wilt, soil microbial compositions in rhizospheres between wilt-resistant and susceptible melon varieties were analyzed. The results showed that the soil fungal richness in rhizospheres of wilt-resistant melon varieties (MT) was significantly higher than that of wilt-susceptible melon varieties (MS). Additionally, in comparison with MS, soil bacterial compositions, such as Proteobacteria, Bacteroidota, , etc.

Synthesis and crystal structure of (1,8-naphth-yridine-κ ,')[2-(1-pyrazol-1-yl)phenyl-κ , ]iridium(III) hexa-fluorido-phosphate di-chloro-methane monosolvate.

The solvated title salt, [Ir(CHN)(CHN)]PF·CHCl, was obtained from the reaction between 1,8-naphthyridine (NAP) and an orthometalated iridium(III) precursor containing a 1-phenyl-pyrazole (ppz) ligand. The asymmetric unit comprises one [Ir(ppz)(NAP)] cation, one PF counter-ion and one CHCl solvent mol-ecule. The central Ir atom of the [Ir(ppz)(NAP)] cation is distorted-octa-hedrally coordinated by four N atoms and two C atoms, whereby two N atoms stem from the NAP ligand while the ppz ligands ligate through one N and one C atom each.

Ubiquitin Extension Protein UEP1 Modulates Cell Death and Resistance to Various Pathogens in Tobacco.

Ubiquitin (Ub) extension proteins (UEPs) are fusion proteins of a Ub at the N terminus to a ribosomal protein. They are the main source of Ub and the only source of extension ribosomal protein. Although important roles of the Ub-26S proteasome system in various biological processes have been well established, direct evidence for the role of genes in plant defense is rarely reported.
