Genotypic Distribution, Resistance Effects, and Breeding Implications of Rice Blast Resistance Genes in 120 Cultivars Released Over the Past Five Decades

Abstract Rice blast, caused by Magnaporthe oryzae , is a destructive disease worldwide. Deployment of broad-spectrum resistance ( R ) genes is an effective strategy for sustainable disease control, but the actual resistance effects of individual genes and their combinations in co...

Visual and Equipment-Minimized Detection of Avian Metapneumovirus Subtype C by RT-RPA-CRISPR/Cas12a Coupled with Lateral Flow Dipstick

Avian metapneumovirus (aMPV) is the main etiological agent of turkey rhinotracheitis, causing respiratory distress and economic losses in turkeys. While its impact in broilers and laying hens is relatively limited, aMPV subtype C (aMPV/C) is an important pathogen in ducks and wat...

Growth and Metal Partitioning of the High-Biomass Grass Cultivar Minmu 6 Under Graded Cadmium and Lead Exposure

Phytoremediation requires plants that combine high biomass production with tolerance to metal stress. The responses of Pennisetum americanum (L.) Leeke × Pennisetum purpureum Schumach. ‘Minmu 6’ were evaluated in separate pot experiments with Cd at 0 (CK), 1.5 (L-Cd), 10 (M-Cd),...

OsRVE1 and OsRVE2 Promote Salinity Tolerance in Rice by Directly Activating OsSAPK5 and Modulating ABA Signalling

ABSTRACT Soil salinity severely limits rice productivity, yet the transcriptional mechanisms connecting salt stress with abscisic acid (ABA) signalling remain incompletely understood. Here, we identify the MYB‐related transcription factors OsRVE1 and OsRVE2 as positive regulators...

Pan‐genomic analysis of alternative polyadenylation reveals a 3′UTR remodeling regulatory layer controlling salt tolerance in rice

Alternative polyadenylation (APA) generates mRNA isoforms with variable 3'UTR lengths, yet its genetic basis and functional significance at the population level remain unexplored in plants. Here, we present the population-level APA landscape and the APA quantitative trait loci (3...

Integrated Bulk and Single-Nucleus Transcriptomics Characterizes the Developmental and Regional Specialization of Chicken Abdominal Fat-Associated Tissue

Excessive abdominal fat deposition reduces feed efficiency and edible carcass yield in chickens, yet its developmental and regional specialization remains poorly understood. We generated 93 bulk RNA sequencing (RNA-seq) libraries from 15 fat-associated anatomical regions at embry...

Inhibitory Effects and Mechanisms of Thymol Against Fusarium oxysporum, a Pathogen of Stem Base Rot

Background/Objectives: Stem base rot caused by Fusarium oxysporum is a devastating soil-borne disease, yet long-term chemical pesticide application has raised serious environmental and ecological concerns. Thymol, a plant-derived fungicide, demonstrates a favorable safety profile...

Zinc Fertilization Mitigates Boron Toxicity in Citrus: Plant Growth, Tissue Mineral Composition and Antioxidant Enzyme Activity

Boron (B) toxicity is a common issue in Citrus production regions worldwide. Zinc (Zn) has been reported to mitigate B toxicity in plants, but the underlying regulatory mechanisms remain poorly elucidated in Citrus. In this study, ’Sweet orange’ (Citrus sinensis) and ’Sour pomelo...

Genome-Wide Identification of the LdARF Gene Family in Lilium davidii var. unicolor and Transient Functional Analysis of LdARF17 in Bulblet Regeneration

Auxin response factors (ARFs) are key transcriptional regulators of the auxin signaling pathway and play important roles in plant organogenesis and regeneration. However, the functions of ARF family genes in lily scale-derived bulblet regeneration remain largely unclear. In this...

2',4′-dimethylacetophenone from Streptomyces roseofulvus St29 suppresses tobacco bacterial wilt by targeting virulence regulation and membrane integrity of Ralstonia solanacearum

Tobacco bacterial wilt, caused by Ralstonia solanacearum , is a destructive soil-borne disease that severely threatens global tobacco production. In this study, fifteen actinobacteria-like strains were isolated from the rhizosphere soil of healthy tobacco plants. Among them, ten...

Ultrasonic Degradation Improves the In Vitro Utilization of Oolong Tea Pectic Polysaccharides: Structure Characterization and Multi-Omics Insights

Pectic polysaccharides from tea residues represent a promising class of prebiotic dietary fibers. This study aimed to optimize the extraction of Oolong tea (Camellia sinensis ‘Foshou’) polysaccharides (FCTP), elucidate the structural alterations induced by ultrasonic degradation,...
