Effects of Tillage Practices and Plastic Film Mulching on Soil Temperature, Dry Matter Production, and Yield Formation of Maize in a Cool Region

Limited thermal resources in the cool regions of Northeast China restrict maize growth and yield formation. A two-year field experiment was conducted in Dunhua, Jilin Province, China, during 2024–2025 using four tillage practices—deep rotary tillage (SX), deep harrowing (SB), dee...

Integrated Soil–Crop System Management Promotes Microbial Necromass and Soil Organic Carbon Sequestration in Black Soil Through Microbial Transformation and Aggregate Protection

Long-term intensive cultivation has degraded soil structure and reduced soil organic carbon (SOC) retention in the black soils of Northeast China. However, the processes underlying SOC accumulation under integrated soil–crop system management (ISSM) remain poorly understood. An 1...

Biological Characteristics and Research Progress of the Rice Leaf Beetle Oulema oryzae (Coleoptera: Chrysomelidae: Criocerinae)

The rice leaf beetle, Oulema oryzae, is a pest across eastern Asia and eastern Russia; both its larval and adult stages cause considerable yield losses through foliar consumption. Its obligate diapause ensures population persistence through adverse seasons, but this strategy also...

Evaluating net energy value of fermented citrus pulp and its effects on performance and egg quality in laying hens

Two experiments were conducted to determine the apparent metabolisable energy (AME), nitrogen-corrected apparent metabolisable energy (AMEn), and net energy (NE) values of fermented citrus pulp (FCP) for layers and to evaluate its effects on performance and egg quality. In Experi...

Strip Tillage with Straw Retention Alters the Associations Between Maize Yield Components and Grain Yield Across Seven Soil Types

Soil degradation constrains cropland productivity in Northeast China, where conservation tillage has been widely adopted to improve soil structure and sustain maize (Zea mays L.) production. However, previous studies have focused mainly on single soil types or regional-scale asse...

A Stacking-Fusion Feature Selection Framework for Cross-Year and Cross-Cultivar Leaf Hyperspectral Rice Yield Estimation

Single-criterion feature selection for hyperspectral crop yield estimation suffers from methodological bias and limited generalisation. This study proposes a stacking-fusion feature selection framework with a ridge-regression meta-learner (STACKING_FUSION) that transfers the stac...

A Gapless T2T Genome and Population-Scale Resequencing of Adzuki Bean Reveal Centromere Evolution and Accelerate Molecular Breeding

Abstract The adzuki bean (Vigna angularis) is an economically and nutritionally significant legume species. Using a multi-strategy sequencing approach, a gapless, telomere-to-telomere (T2T) genome assembly of an elite cultivar, Jihong 16 (JH16), was generated. The genome size was...

Genome-wide identification of the chalcone synthase (CHS) family in tigernut and function analysis of cechs57 in drought stress response

Drought stress is a major abiotic constraint that severely impairs crop growth and reduces yield globally. Identification of drought-tolerant candidate genes and their application in molecular breeding represent effective strategies to alleviate drought-induced losses. Genome-wid...

Transcriptomic profiling and differential alternative splicing of citrus in response to infestation by Asian citrus psyllid, Diaphorina citri

The Asian citrus psyllid, Diaphorina citri Kuwayama, is the principal vector of huanglongbing pathogens and poses a severe threat to citrus production worldwide. Transcriptional and post-transcriptional regulation mediated by alternative splicing (AS) are well-established mechani...
