Genome-wide association analyses reveal genetic loci associated with cold responses in Miscanthus under non-acclimated and cold-acclimated conditions

Miscanthus species are C4 perennial bioenergy crops with broad environmental adaptability, yet episodic freezing events can constrain establishment and productivity. We evaluated cold-response variation in a 144-accession panel comprising 73 M. sacchariflorus and 71 M. lutariorip...

The greenhouse equipped with 29-mesh insect-proof nets and a zipper door enhances insect pest control and yield of bok choy

Abstract The use of insect-proof nets (IPNs) are an environmentally friendly physical method for preventing insect pests from entering the greenhouse and damaging the vegetables. Bok choy Brassica rapa L. subs. chinensis Brassicaceae, a widely cultivated vegetable in China, is co...

Multi-Stage Transcriptomics Reveals TF- and lncRNA-Mediated Regulatory Networks Governing Glyphosate Resistance in Cyperus rotundus

Abstract Glyphosate resistance in Cyperus rotundus, a globally invasive weed, is increasingly threatening crop production, yet its molecular mechanisms remain unclear. Here, we performed multi-stage RNA sequencing of tubers from glyphosate-resistant and -susceptible populations a...

Pleiotropic effects of arnT deletion on colistin resistance, virulence, and stress tolerance in Aeromonas hydrophila are associated with impaired outer membrane homeostasis

Aeromonas hydrophila is a widespread zoonotic and aquatic pathogen posing growing challenges in aquaculture and public health due to increasing antimicrobial resistance and virulence. The arnT gene has been regarded primarily as a mediator of colistin resistance via lipopolysacch...

Lecithin Exhibits Rapid Contact Toxicity Against Bemisia tabaci and Is Associated with Structural and Molecular Responses

Bemisia tabaci is a globally important crop pest and virus vector with widespread resistance to conventional insecticides. We evaluated the insecticidal activity of a soybean-derived lecithin preparation and associated physiological responses. Leaf-surface, dried-residue contact,...

Natural variation in SL6 determines fatty acid components and seed longevity in rice

Seed longevity (SL) is vital for ensuring food security worldwide. However, the genetic basis of SL has been scarcely documented. Here, we report the cloning of a major SL locus, qSL6 , encoding a fatty acyl-ACP thioesterase type B. SL6 is functionally conserved in regulating pal...

Kiwifruit Bacterial Canker Susceptibility of 86 Accessions and Their Physiological Response to Psa Inoculation

Kiwifruit bacterial canker, caused by Pseudomonas syringae pv. actinidiae (Psa), severely restricts the sustainable development of the kiwifruit industry. Screening stable resistant germplasm and establishing efficient disease resistance evaluation methods are core prerequisites...

Spinetoram‐based seed‐pelleting with synergistic mixtures enhances control of the diamondback moth

BACKGROUND: The diamondback moth, Plutella xylostella, is one of the most destructive pests of cruciferous crops worldwide. Its high fecundity, stress tolerance and seasonal migration often render traditional spray control ineffective. In this study, we propose an alternative met...

Attractancy Potentialof Terpinen-4-ol against Bactrocera dorsalis (Hendel) and Its SynergisticAttractant Effects Evaluation

Abstract Bactrocera dorsalis is a major fruit and vegetable pest with limited effective attractants. Our previous work identified Melaleuca quinquenervia essential oil (MQEO) as a strong attractant. Guided by an olfactory transcriptome- and molecular docking-informed screening st...

Establishing a Semen Cryobank for Yan Goose: Optimized Collection and Cryopreservation

Yan goose, a representative Chinese local breed, requires genetic resource conservation. To address this, we optimized a semen cryopreservation protocol for Yan geese and validated its feasibility in large-scale cryobank production. Using motility of frozen-thawed sperm (MFS) as...
