To date, this soilborne disease could only be effectively controlled by planting resistant peanut cultivars. However, the relatively lower yield potential of the available BW-resistant peanut cultivars is a key reason restricting productivity in most epidemic regions naturally infested with the pathogen. Even small pods or seeds and low number per plant has been regarded as the key factor for the low yield potential both in BW-resistant peanut germplasm lines and available released cultivars, whether the resistance is closely linked with key yield components remains unclear. In this study, the relationship between pod weight and BW resistance was analyzed by using a recombinant inbred lines (RIL) population derived from a crossing combination between a high yielding cultivar Xuhua 13 and a BW-resistant cultivar Zhonghua 6. From the experiments, it was found that the BW resistance was not significantly correlated with pod number per plant (PNP), hundred pod weight (HPW) and pod weight per plant (PWP) in the RIL population. Based on linkage analysis, the quantitative trait locus (QTL)s related to PNP were identified on A06, A07, A08 and B03. The QTLs for HPW were detected on A05 and A07, and the QTLs for PWP were on A06, A07 and B03. However, the QTL for BW resistance identified on B02. These results indicated that the BW resistance and the pod number per plant as well as pod weight were inherited independently. Two recombined lines (QT0944 and QT1028) with high level BW resistance and large pods (hundred pod weight over 185g) were identified from the RILs, and they possessed the favored alleles of identified QTLs from both parents, which could be used in peanut breeding for high yield and high level disease resistance.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 1","pages":"Pages 64-69"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, scRNA-seq data are often accompanied by problems such as high noise, high dimensionality and batch effect, resulting in a large number of low-expressed genes and variants, which seriously affect the accuracy and reliability of data analysis. This not only increases the complexity of data processing, but also limits the effectiveness of feature selection and downstream analysis. Although several statistical inference and machine learning methods have been used to address these challenges, the existing methods still have limitations in cell type identification, feature selection, and batch effect correction, which are difficult to meet the needs of complex biological research. In this study, we proposes an innovative single-cell classification method, scIC (single-cell image classification), which converts scRNA-seq data into image form and combines it with deep learning techniques for cell classification. Through this image conversion, we are able to capture complex patterns in the data more efficiently, and then construct efficient classification models using convolutional neural networks (CNN) and residual networks (ResNet). After testing scRNA-seq data from four cell types (mouse skin basal cells, mouse lymphocytes, human neuronal cells, and mouse spinal cord cells), the accuracy of the classification models exceeded 94%, with the mouse skin basal cell dataset achieving a classification accuracy of 99.8% when using the ResNet50 model. These results indicate that image transformation of scRNA-seq data and combining it with deep learning techniques can significantly improve the classification accuracy, providing new ideas and effective tools for solving key challenges in single-cell data analysis.

This change requires innovative and environmentally conscious methods, such as symbiotic-microorganisms-based products. Among these organisms, the genus <em>Trichoderma</em> stands out, as these fungal endophytes reside within many plant species including those in the Brassicaceae family and interact with them positively. Brassicaceae encompass numerous taxa of special agricultural and food interest, such as those known as oilseed brassicas (OSBs). Among these group are crops for obtaining canola and mustard seeds, commonly used for oil and spices production, respectively. OSBs are of greater interest for food because they are rich source of vitamins and minerals, and have also a great antimicrobial, antioxidant and antitumor potential application. Therefore, the improvement of these plant species (or of their cultivation methods) may ultimately lead to an improvement in human food and, accordingly, human health. This progress could go hand in hand with the <em>Trichoderma</em> fungal genus, either based on transgenesis with some of their genes, or using these fungi to formulate and produce bioinoculants. In relation to transgenesis, the most widely studied are those based on <em>Trichoderma</em> genes encoding endochitinases and Kelch-like family proteins, in both cases to achieve an antifungal effect against pathogenic fungi. With regard to <em>Trichoderma</em>-based products, these can be aimed at promoting plant growth, protecting crops against pathogens by acting as biological control agents (BCAs), or even reducing contaminants in the soil, such as heavy metals.
