Threshold-window framework reveals management-sensitive controls of CH4 and N2O emissions in flooded rice

Lulu Yue, Xiangyu Xu, Jianing Wang, Zhang Xian et autres

Rice paddies are major sources of methane (CH 4 ) and nitrous oxide (N 2 O), yet co-managing water and nitrogen (N) to limit both gases remains challenging because emissions arise from non-linear interactions among multiple drivers. We combined a two-year field …

Widespread non-target-site resistance in Setaria viridis to four classes of herbicide

Thomas H. Pendergast, Sailaja Maddali, Srinivasa R. Chaluvadi, Qi Peng et autres

KEY MESSAGE: Although herbicide resistance in Setaria is rampant and cosmopolitian across four herbicide families, we encountered little evidence of target-site resistance, indicating diverse non-target mechanisms of metabolizing, sequestering, and overwhelming herbicides. Setaria viridis is a cosmopolitan weed and model genetic system …

Establishment of Laboratory Bioassay System for Phyllotreta striolata Larvae and Screening of Novel Bt Cry Proteins

Leqi Wang, Z Liu, Ivan M. Dubovskiy, Changlong Shu et autres

Phyllotreta striolata is a global pest of cruciferous vegetables, and controlling its soil-dwelling larvae is challenging. The lack of standardized larval bioassay methods hinders the screening of effective biocontrol agents. In this study, we established a stable and standardized laboratory-efficacy trial system …

Multimodal cross-attention network for overgrowth detection in strawberry seedlings

Zhenzhen Cheng, Yifan Cheng, Tingting Fang, Man Zhu et autres

Early warning of overgrowth in strawberry seedlings is essential to balance vegetative and reproductive growth. However, existing monitoring methods face major challenges, including subtle visual symptoms and limited abnormal samples. To address this, we propose MM-CAPNet, a multimodal fusion framework for early …

Elevation Information Extraction Scheme Based on Sub‐Aperture Correlation Using Airborne Circular Synthetic Aperture Radar Imaging

Hongtu Xie, Qi Peng, Yangyang Xiao, Nannan Zhu

ABSTRACT Airborne circular synthetic aperture radar (CSAR) enables multiangle observation and high‐resolution imaging, which can extract the elevation information. However, the traditional elevation extraction methods are limited by the low elevation extraction accuracy and complicated processing flow. Thus, an elevation information extraction …

High‐Precision Airborne Circular SAR Imaging Method Based on Sub‐Aperture Autofocusing Combined With Terrain Undulation Error Compensation

Hongtu Xie, Qi Peng, Yangyang Xiao, Nannan Zhu

ABSTRACT Airborne circular synthetic aperture radar (CSAR) has the ability of multiangle observation and high‐resolution imaging in remote sensing applications, but its imaging performance is often degraded by the platform motion error and terrain undulation error. To address this issue, a high‐precision …

Comprehensive evaluation and analysis of production performance and nutritional value of 12 Medicago sativa varieties in the Hexi Corridor

LU Yufu, He ZengGuo, ZHAO Jun, Xiaoping Wang et autres

This experiment aimed to screen Medicago sativa varieties suitable for cultivation in the Hexi Corridor region. Twelve domestic and international Medicago sativa varieties were selected, and their agronomic traits, forage yield, and nutritional quality indicators were measured to comprehensively evaluate the production …

Development of a Reverse-Transcription Loop-Mediated Isothermal Amplification Assay for Detecting Brassica Yellows Virus in China

Linlin Du, Feng Zhu, Qi Peng, Tao Li et autres

Brassica yellows virus (BrYV) mainly infects cruciferous crops and has been widely prevalent across China. To develop a rapid and highly sensitive method for detecting BrYV in oilseed rape, a reverse-transcription loop-mediated isothermal amplification (RT-LAMP) assay was established. Four specific primers were …

Long-Term Nitrogen Addition Promotes Microbial Mineralization of Organic Phosphorus Supporting Phosphorus Uptake in Spring Wheat

Huaqiang Li, Qi Peng, Xiaojiao Wang, Ryan W. Gan et autres

The mechanism of microbial-mediated mineralization of organic phosphorus (P) under nitrogen (N) addition in farmland soil is still unclear. To determine the effects of N addition on the composition, structure, and P transformation function of microbial community and soil P fractions in …
