Restoring such images is therefore crucial for reliable spore identification and downstream analysis. However, microscopic defocus is a spatially varying process that severely suppresses high-frequency structures, causing natural-image deblurring models to generalize poorly. In addition, optical constraints of microscopy make realistic sharp-blur pairs difficult to obtain, further limiting learning-based restoration. To address these challenges, we propose MicroDeblurNet, a single-image deblurring network specifically designed for microscopic defocus restoration. The model incorporates a convolutional block attention module to enhance spatial selectivity toward key pathogen structures, and employs depthwise over-parameterized convolutions to capture locally varying blur patterns more effectively, enabling spatially consistent and structurally coherent restoration. Furthermore, a spatial-frequency consistency loss is proposed to strengthen high-frequency detail recovery while maintaining color fidelity and morphological integrity. To support high-fidelity supervision, we propose a paired-data construction strategy based on Laplacian-pyramid fusion and construct a clear-blur microscopic dataset for cucumber downy mildew. The restored outputs of MicroDeblurNet are further applied to sporangia detection and semantic segmentation to evaluate their impact on high-level visual tasks. Finally, we build an integrated microscopic analysis platform that delivers standardized high-quality data and automated pathogen-structure recognition and analysis to support disease assessment and management. Experimental results demonstrate that MicroDeblurNet achieves an optimal balance across pixel-level, structure-level, and perception-level metrics, reaching a PSNR of 42.48 dB and SSIM of 0.9839, outperforming advanced state-of-the-art methods. In downstream tasks, MicroDeblurNet delivers higher detection recall and segmentation accuracy in challenging scenarios involving sporangia adhesion and background impurities, demonstrating its ability to enhance target discernibility, preserve structural completeness, and improve robustness under complex microscopic conditions.</p>","PeriodicalId":20100,"journal":{"name":"Plant Methods","volume":" ","pages":"16"},"PeriodicalIF":4.4,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12888288/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145960017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate species identification is crucial for management but is traditionally based on morphological traits that require expert knowledge, limiting accessibility and early detection. Hyperspectral imaging, a technique that captures detailed reflectance information across hundreds of narrow and contiguous wavelength bands, offers the potential to non-invasively monitor plant health with high precision. This study aimed to explore whether hyperspectral imaging, combined with machine learning algorithms, can accurately differentiate between host plant tissue and parasitic Cuscuta species and further distinguish among different species within the genus. RESULTS: Hyperspectral images were collected in both the visible-near infrared and short-wave infrared ranges, followed by preprocessing and segmentation of plant material from the background. The Normalized Difference Vegetation Index method yielded the most consistent segmentation performance. Random Forest and Neural Network models trained on segmented pixels achieved high classification accuracy and balanced F1 scores of approximately 0.97 in both binary (host versus parasite) and multiclass (species-level) classification. Feature selection using a genetic algorithm and an iterative elbow method successfully reduced the number of spectral bands needed for accurate predictions, identifying key wavelengths associated with chlorophyll content and other biochemical markers. CONCLUSIONS: This study demonstrates the effectiveness of hyperspectral imaging combined with machine learning for identifying and classifying parasitic Cuscuta species.

This species has evolved a unique single-cell C4 (SCC4) photosynthetic pathway, where both C4 and C3 cycles are compartmentalized within a single cell, and demonstrates superior photosynthetic efficiency. This distinctive physiological adaptation makes S. aralocaspica an intriguing model for investigating the photosynthetic mechanism and its environmental adaptation in plants. However, efficient and rapid transformation systems are still lacking for this species. This gap has significantly hindered the dissection of the molecular regulatory networks underlying the SCC4 photosynthetic structure formation and the stress resistance mechanisms. RESULTS: Through systematic optimization of enzymatic digestion parameters and leaf pretreatment methods, we developed an efficient protoplast isolation and transient transformation system for S. aralocaspica. The highest protoplast yield (1.1 × 105/g FW) and viability (64%) were obtained from young leaves under optimized condition: enzyme solution containing 0.75% cellulase R-10 and 0.25% macerozyme R-10, 1.3 M glucose as osmotic regulator, with transverse/longitudinal leaf sectioning combined with epidermal peeling. Protoplast quality was verified by organelle fluorescence staining using different organelle markers. The highest transfection efficiency (75%) was achieved using protoplasts isolated under optimal conditions and transfected with 2400 ng/µL plasmid (5 µg total). Subcellular localization analysis revealed localization of key photosynthetic enzyme SaPEPC1 in the cytoplasm and chloroplasts, and nuclear localization of transcription factor SabHLH169. CONCLUSIONS: In summary, we established a simple and efficient system for isolating and transiently transforming S. aralocaspica chlorenchyma protoplasts. This system is shown to express exogenous proteins with the proper subcellular localization, and it provides a platform for further research on S. aralocaspica, including potential applications in somatic cell fusion, genome editing, and signal transduction and transcriptional regulation studies.
