Characterization and structural analysis of a versatile aromatic prenyltransferase for imidazole-containing diketopiperazines.

Prenylation modifications of natural products play essential roles in chemical diversity and bioactivities, but imidazole modification prenyltransferases are not well investigated. Here, we discover a dimethylallyl tryptophan synthase family prenyltransferase, AuraA, that catalyzes the rare dimethylallylation on the imidazole moiety in the biosynthesis of aurantiamine. Biochemical assays validate that AuraA could accept both cyclo-(L-Val-L-His) and cyclo-(L-Val-DH-His) as substrates, while the prenylation modes are completely different, yielding C2-regular and C5-reverse products, respectively.

Sodium dodecyl sulfate-coated silver nanoparticles accelerate antimicrobial potentials by targeting amphiphilic membranes.

Compelling concerns about antimicrobial resistance and the emergence of multidrug-resistant pathogens call for novel strategies to address these challenges. Nanoparticles show promising antimicrobial activities; however, their actions are hindered primarily by the bacterial hydrophilic-hydrophobic barrier. To overcome this, we developed a method of electrochemically anchoring sodium dodecyl sulfate (SDS) coatings onto silver nanoparticles (AgNPs), resulting in improved antimicrobial potency.

CRISPR/Cas9-mediated knockout of GhAMS11 and GhMS188 reveals key roles in tapetal development and pollen exine formation in upland cotton.

The ABORTED MICROSPORES (AMS) gene is crucial for tapetal cell development and pollen formation, but its role in Upland cotton (Gossypium hirsutum) has not been previously documented. This study identified GhAMS11 as a key transcription factor, with its high expression specifically observed during the S4-S6 stages of anther development, a critical period for tapetal activity and pollen formation. Subcellular localization confirmed that GhAMS11 was located in the nucleus.

Analysis of 92,967 AAGs in , , and 74 other plant species shows that 45.69% of AAGs are polyploidy-related, highlighting polyploidy's role in linking autophagy to plant-specific functions.

Comprehensive multi-tissue epigenome atlas in sheep: A resource for complex traits, domestication, and breeding.

Comprehensive functional genome annotation is crucial to elucidate the molecular mechanisms of agronomic traits in livestock, yet systematic functional annotation of the sheep genome is lacking. Here, we generated 92 transcriptomic and epigenomic data sets from nine major tissues, along with whole-genome data from 2357 individuals across 29 breeds worldwide, and 4006 phenotypic data related to tail fat weight. We constructed the first multi-tissue epigenome atlas in terms of functional elements, chromatin states, and their functions and explored the utility of the functional elements in interpreting phenotypic variation during sheep domestication and improvement.

The South China Sea Mooring Array and its applications in exploring oceanic multiscale dynamics.

The South China Sea (SCS) is abundant with complex multiscale dynamic processes but their spatiotemporal variations, generation and evolution mechanisms, and mutual interactions remain inadequately understood due to the lack of long-term in situ observations. To explore oceanic multiscale dynamics in the SCS, the SCS Mooring Array (SCSMA) was began to be constructed since 2009. The SCSMA consists of ∼40 moorings and is the largest in situ ocean observing system in marginal seas worldwide.

Machine learning-based forecasting of ground surface settlement induced by metro shield tunneling construction.

Urban rail transit systems, represented by subways, have significantly alleviated the traffic pressure brought by urbanization and have addressed issues such as traffic congestion. However, as a commonly used construction method for subway tunnels, shield tunneling inevitably disturbs the surrounding soil, leading to uneven ground surface settlement, which can impact the safety of nearby buildings. Therefore, it is crucial to promptly obtain and predict the ground surface settlement induced by shield tunneling construction to enable safety warnings and evaluations.

The effect of calf muscular vein thrombosis on the prognosis within one year postoperatively of geriatric hip fracture patients: a propensity score-matched analysis.

Introduction: Calf muscular vein thrombosis (CMVT) is a type of distal deep vein thrombosis, which is common in geriatric hip fracture patients. However, studies focusing on whether the orthopedic operation has an impact on the prognosis of geriatric hip fracture patients with CMVT are very limited.
