Carbohydr Polym

November 2025

State Key Laboratory of Crop Gene Resources and Breeding, National Key Facility for Crop Gene Resources and Genetic Improvement, Institute of Crop Science, Chinese Academy of Agricultural Sciences, Beijing 100081, China. Electronic address:

Amylose content (AC) is a key determinant of wheat quality, and the TaWaxy gene determined amylose synthesis with a dose-dependent effect on AC. In this study, the TaWOX5 gene, which significantly enhances wheat transformation efficiency, was combined with CRISPR/SpCas9 system to generate TaWaxy mutants in a commercial winter wheat Jimai 22. Seven transgene-free mutant types were produced, compared to only three transgene-free mutants in the spring wheat variety Ningchun 4.

The inefficiency of traditional pesticides leads to significant resource waste, severe environmental pollution, and potential threats to human health. Pesticide microcapsules present a promising strategy for developing environmentally friendly, safe, and sustained-release formulations. In this study, we produced degradable starch nanocrystals (SNCs) via acid hydrolysis and employed octenyl succinic anhydride-modified SNCs (O-SNCs) to fabricate pesticide microcapsules.

Risk prediction and driver tracking based on watershed resilience dynamics: A case study in Dahei River Basin, China.

Environ Res

September 2025

Key Laboratory for Mechanics in Fluid Solid Coupling Systems, Institute of Mechanics, Chinese Academy of Sciences, Beijing, 100190, China.

The watersheds face increasing pressure from both human activities and natural factors, which exacerbate potential risks and pose significant challenges to integrated watershed management. This study developed an effective methodology to evaluate watershed sustainability and predict potential risks based on watershed resilience dynamics by combining catastrophe theory, adaptive cycle theory, and the Copula-Bayesian Network. Taking the Dahei River Basin (DRB) in China as a case study, we systematically evaluated the resilience dynamics, diagnosed risks, and tracked key driving factors to propose management strategies.

LlLRP1, an SHI/SRS transcription factor, mediates bulbil formation in Lilium lancifolium via regulation by LlWOX11 and response to NaCl stress.

Int J Biol Macromol

September 2025

State Key Laboratory of Vegetable Biobreeding, Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, Beijing, 100081, China; College of Landscape Architecture and Horticulture Sciences, Southwest Forestry University, Kunming, Yunnan, 650224, China. Electronic address: mingju

Bulbil formation in Lilium lancifolium represents a pivotal vegetative reproduction strategy, yet the transcriptional regulatory network governing this process remains largely uncharacterized. Here, we identify LlLRP1 by full-length cloning, sequence analysis and subcellular localization, an SHI/SRS family transcription factor, as a key mediator of bulbil morphogenesis. Transcriptomic profiling revealed that LlLRP1 is a downstream target of LlWOX11, with its promoter harboring conserved binding motifs (AAAG, AGTA) validated by yeast one-hybrid, dual-luciferase reporter, and electrophoretic mobility shift assays.

State Key Laboratory for Quality and Safety of Agro-Products, Institute of Quality Standards and Testing Technology for Agro-Products, Chinese Academy of Agricultural Sciences, Beijing 100081, China. Electronic address:

Cattle-yaks are increasingly cultivated to boost yak dairy production while reports claim that will decrease the nutritional value of yak milk. However, studies on protein composition differences, especially functional proteins, between yak and cattle-yak milk are limited. This study explores these differences using data-independent acquisition (DIA) proteomics to compare whey proteins and milk fat globule membrane (MFGM) proteins in both types of milk.

September 2025

State Key Laboratory of High-efficiency Utilization of Coal and Green Chemical Engineering, College of Chemistry and Chemical Engineering, Ningxia University, Yinchuan, Ningxia, 750021, P. R. China.

Electrochemical CO reduction (CORR) to carbon monoxide (CO) offers a sustainable pathway for carbon utilization, yet challenges remain in terms of improving selectivity and activity. Herein, we report a Ni/NC catalyst synthesized via a milling - pyrolysis method, in which Ni particles anchored on nitrogen-doped carbon (NC) are electrochemically activated under an Ar atmosphere, leading to their structural evolution into single-atom Ni sites. After activation in Ar atmosphere, the current density nearly doubles (from ≈30 to ≈60 mA cm), and concurrently, the Faradaic efficiency of CO stays at ∼90% with the potential set to -0.

September 2025

State Key Laboratory for Quality and Safety of Agro-Products, Institute of Quality Standards and Testing Technology for Agro-Products, Chinese Academy of Agricultural Sciences, Beijing 100081, People's Republic of China.

As a newly recognized type of emerging contaminant, liquid crystal monomers (LCMs) are widely distributed in the environment and human consumptions and their effects on visual systems and the underlying mechanisms are yet to be elucidated. Therefore, this study investigated the visual-neuro influence of 3cH2B (a frequently detected LCM) under environmentally relevant concentrations in zebrafish. The findings revealed that 40 μg/L 3cH2B induced visual behaviors after 40 days of exposure, which was accompanied by decreased retinoic acid (RA) levels and retinal structural deformation in the eyes.

September 2025

Laboratory of Advanced Breeding Technologies, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Beijing 100101, China.

Polyploidization is a driving force of wheat (Triticum aestivum) evolution and speciation, yet its impact on epigenetic regulation and gene expression remains unclear. Here, we constructed a high-resolution epigenetic landscape across leaves, spikes, and roots of hexaploid wheat and its tetraploid and diploid relatives. Inter-species stably expressed genes exhibited conserved amino acid sequences under strong purifying selection, while dynamically expressed genes were linked to species-specific adaptation.

Residues 27T and 297A in VP2 contribute to the enhanced replication and pathogenicity of raccoon dog parvovirus.

J Virol

September 2025

Key Laboratory of Special Animal Epidemic Disease, Ministry of Agriculture, Chinese Academy of Agricultural Sciences, Institute of Special Animal and Plant Sciences, Changchun, China.

Raccoon dog parvovirus (RDPV) is a highly contagious pathogen causing severe hemorrhagic enteritis that is fatal in young raccoon dogs. Since 2016, epidemiological investigations have documented recurrent outbreaks of RDPV, exhibiting heightened virulence; however, the molecular mechanisms driving this increased pathogenicity remain poorly understood. In this study, an alignment of 67 complete RDPV sequences identified two high-frequency amino acid mutations at positions 27 and 297 in the VP2 capsid protein that distinguish RDPV strains from before and after the 2016 outbreak.

Chinese Academy of Agriculture Mechanization Sciences Group Co., Ltd., Beijing, China.

Intercropping maize and soybean with distinct plant heights is a typical practice in diversified cropping systems, where shadows cast by taller maize plants onto soybean rows pose significant challenges for image based recognition. This study conducted experiments throughout the entire soybean-maize intercropping period to address illumination variation. Based on the height difference between crops, solar elevation angle, and light intensity at the top of the soybean canopy, an illumination compensation regression model was developed.

Abiotic stresses severely threaten global food security, underscoring the need for resilient crop varieties. We identified OsSPT38, a previously uncharacterized SUMO E3 ligase in rice, and discovered a rare gain-of-function mutation (Gly212Asp) that enhances both stress resilience and yield. This phenotype was validated in 18 additional independent mutants and by base editing in the elite indica cultivar Huanghuazhan.

This study investigates how agricultural disturbance influences arbuscular mycorrhizal (AM) fungal diversity, biomass, and community niche structure. Utilizing niche concepts, we show that the AM fungal communities in intensively managed soils exhibited larger niche volumes and an increased proportion of culturable taxa, which negatively impacted biomass production. This process was primarily driven by the reduction in specialist taxa, indicating a functional homogenization of the community.
