Tsinghua Science and Technology 2024年第4期29卷 1194-1205页

Deep learning based techniques are broadly used in various applications, which exhibit superior performance compared to traditional methods. One of the mainstream topics in computer vision is the image super-resolution task. In recent deep learning neural networks, the number of parameters in each convolution layer has increased along with more layers and feature maps, resulting in better image super-resolution performance. In today’s era, numerous service providers offer super-resolution services to users, providing them with remarkable convenience. However, the availability of open-source super-resolution services exposes service providers to the risk of copyright infringement, as the complete model could be vulnerable to leakage. Therefore, safeguarding the copyright of the complete model is a non-trivial concern. To tackle this issue, this paper presents a lightweight model as a substitute for the original complete model in image super-resolution. This research has identified smaller networks that can deliver impressive performance, while protecting the original model’s copyright. Finally, comprehensive experiments are conducted on multiple datasets to demonstrate the superiority of the proposed approach in generating super-resolution images even using lightweight neural networks.

Structure, variation and assembly processes of bacterial communities in different root-associated niches of tomato under periodic drought and nitrogen addition

引用

Pedosphere 2024年第5期34卷 892-904页

作者： Dan he Ruifeng GAO Honghong DONG Xiaodi LIU Lijuan REN Qinglong WU Qing YAO honghui ZHU Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou) Key Laboratory of Agricultural Microbiomics and Precision Application (MARA) State Key Laboratory of Applied Microbiology Southern China Institute of Microbiology Guangdong Academy of Sciences College of Plant Protection South China Agricultural University Department of Ecology Institute of Hydrobiology Jinan University College of Horticulture South China Agricultural University

Root-associated bacteria play a vital role in the growth and adaptation of host plants to drought stress. These bacteria can be classified as rhizoplane and rhizosphere bacteria based on their distance from the root surface. Tomato plants are often exposed to periodic drought and nitrogen (N) addition throughout their life cycle, but the impacts of these factors on the plant and root-associated bacteria are not well understood. To gain insight into this relationship, we conducted an experiment to monitor the effects of periodic drought and N addition on rhizoplane and rhizosphere bacteria of tomato plants. Drought and N addition had interactive effects on plant and soil properties, which varied with the timing of drought. There were clear divergences in community traits such as alpha diversity, beta diversity, and network topological features between the two types of bacteria. The rhizoplane bacteria showed lower alpha diversity but higher beta diversity and were more sensitive to drought and N addition than the rhizosphere bacteria. Nitrogen addition could downsize the effects of drought on rhizoplane bacterial community compositions. The higher proximity to the root might induce a community to develop more cooperation between different members to cope with plant metabolites, as revealed by the more connected and modularized community network of the rhizoplane bacteria. Drought at the seedling stage had great legacy effects on plant and soil properties. It may enhance selection, cause the dominance of deterministic processes in the assembly of rhizoplane bacteria, and reduce bacterial community network complexity. In conclusion, N addition could interact with drought in affecting tomato plants and their root-associated bacteria, depending on the timing of drought and the fineness of root niches. The higher sensitivity of rhizoplane bacteria to drought and N addition calls for more research due to their higher proximity and importance to plants in future environment
