Summary: This study identified a MYB transcription factor gene, PlMYB308, which plays an important regulatory role in the senescence process of herbaceous peony flowers. PlMYB308 is regulated by endogenous hormones and modulates flower senescence by regulating hormone levels. PlMYB308 specifically binds the promoter of PlACO1 and further regulates ethylene production. Modulation of PlMYB308 and PlACO1 can delay flower senescence and extend the vase life of the flowers.

Summary: Biomolecules-mediated biomimetic mineralization has been extensively studied and applied to fabricate nano-assemblies with unique hierarchical architectures and properties. In this research, a confined diffusion method was used to mimic the in vivo condition, resulting in the formation of hydroxyapatite nanoflower assemblies (HNAs) with delicate hierarchical architectures. The study revealed that strong interactions between ions and hyaluronan played a crucial role in the nucleation and aggregation of hydroxyapatite, and the self-assembling process was induced by external diffusion field and internal multiple interactions. Moreover, HNAs showed colloid stability and excellent biocompatibility, making them a promising carrier for intranuclear delivery.

The study also investigated the effects of catalyst dosage, pH values, inorganic anions, and capture agents on the photodegradation performance of rhodamine B.

Summary: The rational design of catalysts with 3D open structures is crucial for improving catalytic performance. In this study, a hierarchical flower-like Ni-Mo bimetallic catalyst was synthesized using levulinic acid as the template reaction and nitrogen-rich dual ligand MOF as the sacrificial template. The Ni-Mo bimetallic component was uniformly dispersed on petal-shaped nanosheets due to the anchoring effect of N-C defects. The introduction of doped Mo enhanced the dispersion of Ni species and acidity of the catalyst, resulting in the excellent performance of the catalyst for the valorization of levulinic acid to gamma-valerolactone.

Summary: In this study, a synthetic electrozyme was coupled with a supramolecule-assembled nanoarchitecture to mimic mitochondrial oxidative phosphorylation and achieve enhanced bioenergy transformation. The metal-free electrozyme, a semiconducting polymer deposited on an electrode, exhibited a well-matched electrocatalytic property that allowed the oxidation of reduced nicotinamide adenine dinucleotide (NADH) to release protons at a much lower electric potential. As a result, a proton gradient was generated and drove the rotary catalysis of adenosine 5'-triphosphate (ATP) synthase in a lipid membrane, resulting in the production of ATP. Significantly, the electrochemical bioenergy conversion of NADH to ATP in this bio-like system was much more efficient compared to natural mitochondria. This work integrates synthetic and natural catalytic chemistry, facilitating enhanced bioenergy transformation and greatly improving prospects in ATP-fueled bioapplications.

Summary: The self-assembling behavior of peptides and derivatives plays a crucial role in constructing architectures and achieving specific functions in nature. However, the surface or interfacial self-assembly, especially on micro- or nanoparticles, has been less systematically studied. In this study, uniform porous CaCO3 micro particles with different surfaces were used to investigate the self-assembling behavior of dipeptides with various sequences. The experimental results showed that dipeptides with a negative charge preferentially self-assembled on the hydrophobic and positively charged surface of CaCO3 particles, and dipeptides with high Log p values had a significant effect on the self-assembling behavior on the surface of porous CaCO3.
