“…The dual culture technique was used to screen isolates with antagonistic activity against FocTR4 14,013 strain and other pathogens, such as Alternaria alternata, Calonectria ilicicola (Chen et al, 2022), Colletotrichum gloeosporioides, F. oxysporum from Morinda officinalis (Dong et al, 2019), Helminthosporium maydis, Lasiodiplodia pseudotheobromae (Chen et al, 2020), and Stagonosporopsis pogostemonis (Luo et al, 2022). All of the strains were cultured by PDA plates at 28°C.…”

Fusarium oxysporum f. sp. cubense tropical race 4 (FocTR4) is a devastating phytopathogen responsible for significant losses in banana production worldwide. Trichoderma and other biocontrol agents (BCAs) have been used as suitable disease control methods for banana Fusarium wilt. In this study, the endophytic T. koningiopsis Tk905 strain was isolated from the roots of dendrobe plants and identified utilizing morphological and molecular analyses. Antifungal activity tests revealed that Tk905 effectively inhibited mycelial growth with inhibition rates ranging from 26.52 to 75.34%. Additionally, Tk905 covered the pathogen mycelia, and spores were observed on or around the pathogen hyphae. The average root and shoot fresh weights and plant height, of Tk905-inoculated plants were significantly higher than those of the untreated plants. Furthermore, Tk905 treatment significantly increased the activity of antioxidant enzymes, such as catalase (CAT), phenylalanine ammonia-lyase (PAL), polyphenol oxidase (PPO), and peroxidase (POD), suggesting that Tk905 may enhance plant defence systems by activating their antioxidant mechanisms. Most importantly, Tk905-treated plants inoculated by three methods exhibited significantly lower disease incidence and severity than untreated plants. The protective effects of Tk905 against FocTR4 infection were not only observed in the early stages of infection but persisted throughout the experiment, suggesting that T. koningiopsis Tk905 can provide long-lasting protection against Fusarium wilt.

“…The sequence showed 1930 and 1718 putative secretory proteins in F018 and Ci14017, respectively. Based on the genome information, Chen et al (2022) identified 46 virulence-associated genes in Ci14017 through a comparison of transcriptomes and proteomes between resistant and susceptible peanut cultivars. These genome information resources will greatly facilitate studies on the pathobiology of C. ilicicola and inform an effective RCR management strategy.…”

“…The whole genome sequence of C . ilicicola has been decoded recently using the F018 strain isolated from diseased soybean plants (Liu et al, 2021) and the Ci14017 strain isolated from diseased peanut plants (Chen et al, 2022); the size of the whole genome comprised 66 Mb, encoding 17,308 and 18,366 hypothetical proteins, respectively. The sequence showed 1930 and 1718 putative secretory proteins in F018 and Ci14017, respectively.…”

Soybean red crown rot: Current knowledge and future challenges

Soybean red crown rot (RCR) is caused by the soilborne fungal pathogen Calonectria ilicicola. It causes root rot, leaf senescence, early defoliation, plant wilting and even death, often resulting in a severe reduction in seed yield and quality. C. ilicicola is an extremely difficult pathogen to control owing to its wide host range and long survival in soil and plant debris. Currently, no practically effective fungicide for this pathogen is available. Breeding for resistance is considered the most effective and environmentally acceptable means of disease management, but no C. ilicicola‐resistant soybean variety has yet been identified. Given this situation, it is necessary to promote our understanding of the mechanism of RCR incidence and the development of a comprehensive and sustainable RCR management strategy urgently.

tvBOT is a user-friendly and efficient web application for visualizing, modifying, and annotating phylogenetic trees. It is highly efficient in data preparation without requiring redundant style and syntax data. Tree annotations are powered by a data-driven engine that only requires practical data organized in uniform formats and saved as one table file. A layer manager is developed to manage annotation dataset layers, allowing the addition of a specific layer by selecting the columns of a corresponding annotation data file. Furthermore, tvBOT renders style adjustments in real-time and diversified ways. All style adjustments can be made on a highly interactive user interface and are available for mobile devices. The display engine allows the changes to be updated and rendered in real-time. In addition, tvBOT supports the combination display of 26 annotation dataset types to achieve multiple formats for tree annotations with reusable phylogenetic data. Besides several publication-ready graphics formats, JSON format can be exported to save the final drawing state and all related data, which can be shared with other users, uploaded to restore the final drawing state for re-editing or used as a style template for quickly retouching a new tree file. tvBOT is freely available at: https://www.chiplot.online/tvbot.html.
