The D380 residue in MCO1 regulates neural iron homeostasis and fitness in Drosophila

Iron dyshomeostasis has been implicated in the aging and pathogenesis of numerous neurodegenerative diseases, however, the underlying mechanisms are largely unknown. Previously, we determined that Drosophila melanogaster multicopper oxidase-1 (MCO1) has dual-functional catalytic...

Parameter Optimization of Companion Particles and Anti-Blocking Mechanism for Sesame Seed Metering in a Binary Sesame–Companion Particle System

Sesame seeds are small, irregularly shaped, and poorly flowable, often causing insufficient filling and unstable discharge in external fluted-roller seed-metering devices. This study developed a sesame–companion-particle binary seed-metering system to improve metering stability....

CFD-DEM Evaluation of Particle Circulation and High-Percentile Contact Loading in a Draft-Tube Fluidized-Bed Seed Coater for Chinese Cabbage Seeds

Stable circulation and limited mechanical loading are key requirements in the fluidized-bed coating of small vegetable seeds. For Chinese cabbage seeds, their small mass, irregular geometry, and mechanical sensitivity make it difficult to evaluate operating conditions using only...

Environmental modulation of competition effects on intra-seasonal radial growth in planted larch forests of north China

Competition and hydrothermal conditions jointly regulate tree growth, yet competitive effects are commonly assumed to be temporally constant and are usually assessed at annual scales. Such approaches may obscure periods within the growing season when competition becomes growth-li...

Discovery of 3-Carboxyl-4-pyrazolamides as Promising Herbicidal Scaffolds Targeting Dihydroorotate Dehydrogenase

Abstract Enhancing innovation in herbicide discovery is imperative to combat weed resistance and safeguard global food security. To develop novel herbicide targeting dihydroorotate dehydrogenase (DHODH), a series of 3-carboxy-4-pyrazole amide lead scaffold bearing ester or acid s...

Research on seedling grading of Platycladus orientalis based on fuzzy C-means clustering algorithm improved by genetic sparrow family search optimization

Platycladus orientalis has high ecological and economic value, but the quality of Platycladus orientalis seedlings varies greatly. The original quality grading standard is relatively simple and the grading boundary is not clear. It is of great significance to use the in-situ Elec...

Early Compound Nutritional Intervention Improves Hair Follicle Development in Northwest Xizang White Cashmere Goats: An Analysis Based on Skin Multi-Omics

The Northwest Xizang White Cashmere goat has a high global reputation for good goat cashmere germplasm characteristics, and its cashmere industry is the economic pillar of the herdsmen in the northwest plateau of Xizang. Cashmere is produced by the secondary hair follicles of the...

DualSlim-YOLO: A Lightweight Detection Model Based on Unmanned Aerial Vehicle Imagery for Cauliflower Seedling Identification and Growth Assessment

Cauliflower emergence rate and seedling growth are key indicators of field conditions and varietal potential. Traditional manual surveys are unsuitable for continuous monitoring across multiple varieties. This study integrates UAV RGB imagery with the DualSlim-YOLO model to estim...

Natural variation in the PmbHLH162 promoter regulates anthocyanin biosynthesis and accumulation in Prunus mume

Anthocyanin accumulation is a vital agronomic and ornamental trait, as it not only contributes to adaptation to environmental stress but also enhances ornamental value. In this study, a genome-wide association study (GWAS) was conducted using 328 accessions of mei (Prunus mume) t...

Design and Testing of a Dual Air-Guiding Variable-Rate Spraying System Based on Vision Perception and Control

A dual air-guiding variable-rate spraying system based on vision perception and control was developed to address two limitations of conventional air-assisted sprayers in high-spindle, high-density apple orchards: insufficient airflow to the upper canopy, which results in poor spr...

Root Ion flux and transcriptomic analyses reveal the response mechanisms of Gleditsia sinensis seedlings to salt stress

Abstract Gleditsia sinensis Lam. is a widely distributed tree species in China characterized by its remarkable tolerance to barrenness and salinity, making it a valuable candidate for the ecological restoration of saline-alkali lands. Understanding its ion regulatory mechanisms i...

High-Quality Complete Genome Assembly of Bacillus velezensis BV2007 and Genomic Insights Into Its Potential for Biocontrol of Apple Valsa Canker

The previous studies in our laboratory have shown that Bacillus velezensis strain BV2007 exhibits a significant biocontrol effect against apple tree canker. In this study, the complete genomic sequence and annotation information of the strain were obtained by using PacBio Revio p...

Artificial intelligence (AI) offers new opportunities for evidence retrieval, data interpretation, experimentation, feedback, and evidence-based problem solving in engineering education. This study developed a theoretically grounded “One Core, Two Channels, and Four-Dimensional D...

A Robust Mitochondria‐Targeted Photosensitizer Synergizes With Cisplatin Chemotherapy for Enhanced Antitumor Immunity

ABSTRACT Chemotherapy remains a major strategy for cancer treatment, with cisplatin widely used as a first‐line agent for diverse malignancies. Although cisplatin efficiently induces tumor cell death through DNA damage, its therapeutic efficacy is often limited by the development...

Genome-wide characterization of the SnRK gene family in jujube (Ziziphus jujuba Mill.) reveals that ZjSnRK7 and ZjSnRK9 may contribute to salt stress tolerance

During the plant life cycle, biotic and abiotic stresses critically influence survival and development. Sucrose non-fermenting 1-related protein kinases (SnRKs)-a conserved class of key signaling regulators-play a central role in stress response mechanisms shaped by long-term pla...
